Hammunition

Projects that follow the best practices below can voluntarily self-certify and show that they've achieved an Open Source Security Foundation (OpenSSF) best practices badge.

There is no set of practices that can guarantee that software will never have defects or vulnerabilities; even formal methods can fail if the specifications or assumptions are wrong. Nor is there any set of practices that can guarantee that a project will sustain a healthy and well-functioning development community. However, following best practices can help improve the results of projects. For example, some practices enable multi-person review before release, which can both help find otherwise hard-to-find technical vulnerabilities and help build trust and a desire for repeated interaction among developers from different companies. To earn a badge, all MUST and MUST NOT criteria must be met, all SHOULD criteria must be met OR be unmet with justification, and all SUGGESTED criteria must be met OR unmet (we want them considered at least). If you want to enter justification text as a generic comment, instead of being a rationale that the situation is acceptable, start the text block with '//' followed by a space. Feedback is welcome via the GitHub site as issues or pull requests There is also a mailing list for general discussion.

We gladly provide the information in several locales, however, if there is any conflict or inconsistency between the translations, the English version is the authoritative version.
If this is your project, please show your badge status on your project page! The badge status looks like this: Badge level for project 15243 is passing Here is how to embed it:

 Basics 13/13 ●

  • General

    Note that other projects may use the same name.

    Hammunition turns an existing Debian-family install into an amateur radio, SDR, and RF experimentation workstation. A declarative YAML catalog of software and hardware, kept strictly separate from the Python engine that installs it: idempotent, --dry-run accurate, a transaction log, and honest per-distro capability reporting. Primary target Parrot OS; also Debian, Ubuntu, Kali, Linux Mint and Raspberry Pi OS. Every download is verified by a pinned sha256 or refused.

    Please use SPDX license expression format; examples include "Apache-2.0", "BSD-2-Clause", "BSD-3-Clause", "GPL-2.0+", "LGPL-3.0+", "MIT", and "(BSD-2-Clause OR Ruby)". Do not include single quotes or double quotes.
    If there is more than one language, list them as comma-separated values (spaces optional) and sort them from most to least used. If there is a long list, please list at least the first three most common ones. If there is no language (e.g., this is a documentation-only or test-only project), use the single character "-". Please use a conventional capitalization for each language, e.g., "JavaScript".
    The Common Platform Enumeration (CPE) is a structured naming scheme for information technology systems, software, and packages. It is used in a number of systems and databases when reporting vulnerabilities.

    Engine under src/ is GPL-3.0-or-later; the catalog under catalog/ is CC0-1.0 so any other engine may read it. Part of a suite (Hammunition Hill, Devices, Bunker, GPS tether) under the same organization; CI for all of it is the shared, hardened reusable workflows at https://github.com/ChiefGyk3D/git-your-ship-together

  • Basic project website content


    Enough for a badge!

    The project website MUST succinctly describe what the software does (what problem does it solve?). [description_good]
    This MUST be in language that potential users can understand (e.g., it uses minimal jargon).

    https://renegade-penguin.github.io/Hammunition/ states what it does in the first paragraph, in plain language.


    Enough for a badge!

    The project website MUST provide information on how to: obtain, provide feedback (as bug reports or enhancements), and contribute to the software. [interact]

    Obtain: https://renegade-penguin.github.io/Hammunition/getting-started/ (install from a tagged release; checksums and Sigstore bundles on every asset). Feedback: https://github.com/Renegade-Penguin/Hammunition/issues (bugs and enhancements); https://github.com/Renegade-Penguin/Hammunition/security/policy (vulnerabilities, private reporting enabled). Contribute: https://github.com/Renegade-Penguin/Hammunition/blob/main/CONTRIBUTING.md and https://renegade-penguin.github.io/Hammunition/contributing/manifests/


    Enough for a badge!

    The information on how to contribute MUST explain the contribution process (e.g., are pull requests used?) (URL required) [contribution]
    We presume that projects on GitHub use issues and pull requests unless otherwise noted. This information can be short, e.g., stating that the project uses pull requests, an issue tracker, or posts to a mailing list (which one?)

    Work on a branch, merged to main by pull request only; issues on GitHub; CI runs on every pull request. https://github.com/Renegade-Penguin/Hammunition/blob/main/CONTRIBUTING.md


    Enough for a badge!

    The information on how to contribute SHOULD include the requirements for acceptable contributions (e.g., a reference to any required coding standard). (URL required) [contribution_requirements]

    CONTRIBUTING.md ("Before you open a pull request") states the requirements: ruff check and ruff format --check clean; mypy --strict clean (a CI gate); tests pass in the target containers; every pull request that changes src/, catalog/ or docs/guides/ carries a changelog fragment under changelog.d/ (test-enforced); a commit-msg hook and a CI job refuse a commit whose message claims a change the diff does not contain; small, logically scoped commits; documentation is part of the change. https://github.com/Renegade-Penguin/Hammunition/blob/main/CONTRIBUTING.md#before-you-open-a-pull-request and https://renegade-penguin.github.io/Hammunition/contributing/ci/


  • FLOSS license


    Enough for a badge!

    The software produced by the project MUST be released as FLOSS. [floss_license]
    FLOSS is software released in a way that meets the Open Source Definition or Free Software Definition. Examples of such licenses include the CC0, MIT, BSD 2-clause, BSD 3-clause revised, Apache 2.0, Lesser GNU General Public License (LGPL), and the GNU General Public License (GPL). For our purposes, this means that the license MUST be: The software MAY also be licensed other ways (e.g., "GPLv2 or proprietary" is acceptable).

    Engine GPL-3.0-or-later; catalog CC0-1.0. Both OSI/FSF-recognised free licenses. https://github.com/Renegade-Penguin/Hammunition/tree/main/LICENSES


    Enough for a badge!

    It is SUGGESTED that any required license(s) for the software produced by the project be approved by the Open Source Initiative (OSI). [floss_license_osi]
    The OSI uses a rigorous approval process to determine which licenses are OSS.

    GPL-3.0-or-later is OSI-approved. CC0-1.0 is FSF-recognised as free and acceptable to Debian main and Fedora (OSI declined to list it, which is why the engine's license is the GPL).


    Enough for a badge!

    The project MUST post the license(s) of its results in a standard location in their source repository. (URL required) [license_location]
    One convention is posting the license as a top-level file named LICENSE or COPYING, which MAY be followed by an extension such as ".txt" or ".md". An alternative convention is to have a directory named LICENSES containing license file(s); these files are typically named as their SPDX license identifier followed by an appropriate file extension, as described in the REUSE Specification. Note that this criterion is only a requirement on the source repository. You do NOT need to include the license file when generating something from the source code (such as an executable, package, or container). For example, when generating an R package for the Comprehensive R Archive Network (CRAN), follow standard CRAN practice: if the license is a standard license, use the standard short license specification (to avoid installing yet another copy of the text) and list the LICENSE file in an exclusion file such as .Rbuildignore. Similarly, when creating a Debian package, you may put a link in the copyright file to the license text in /usr/share/common-licenses, and exclude the license file from the created package (e.g., by deleting the file after calling dh_auto_install). We encourage including machine-readable license information in generated formats where practical.

    LICENSE at the top level and a REUSE-style LICENSES/ directory holding GPL-3.0-or-later.txt and CC0-1.0.txt; SPDX headers on source files, enforced by tests/test_licensing.py. https://github.com/Renegade-Penguin/Hammunition/tree/main/LICENSES


  • Documentation


    Enough for a badge!

    The project MUST provide basic documentation for the software produced by the project. [documentation_basics]
    This documentation must be in some media (such as text or video) that includes: how to install it, how to start it, how to use it (possibly with a tutorial using examples), and how to use it securely (e.g., what to do and what not to do) if that is an appropriate topic for the software. The security documentation need not be long. The project MAY use hypertext links to non-project material as documentation. If the project does not produce software, choose "not applicable" (N/A).

    Install, first profile and first contact: https://renegade-penguin.github.io/Hammunition/getting-started/ ; task guides: https://renegade-penguin.github.io/Hammunition/guides/ ; secure use (what the consent gates refuse, what runs as root and why, how to inspect and reverse every system change) is written into each guide and into https://renegade-penguin.github.io/Hammunition/reference/cli/


    Enough for a badge!

    The project MUST provide reference documentation that describes the external interface (both input and output) of the software produced by the project. [documentation_interface]
    The documentation of an external interface explains to an end-user or developer how to use it. This would include its application program interface (API) if the software has one. If it is a library, document the major classes/types and methods/functions that can be called. If it is a web application, define its URL interface (often its REST interface). If it is a command-line interface, document the parameters and options it supports. In many cases it's best if most of this documentation is automatically generated, so that this documentation stays synchronized with the software as it changes, but this isn't required. The project MAY use hypertext links to non-project material as documentation. Documentation MAY be automatically generated (where practical this is often the best way to do so). Documentation of a REST interface may be generated using Swagger/OpenAPI. Code interface documentation MAY be generated using tools such as JSDoc (JavaScript), ESDoc (JavaScript), pydoc (Python), devtools (R), pkgdown (R), and Doxygen (many). Merely having comments in implementation code is not sufficient to satisfy this criterion; there needs to be an easy way to see the information without reading through all the source code. If the project does not produce software, choose "not applicable" (N/A).

    The CLI (every verb, flag, exit code and what it refuses): https://renegade-penguin.github.io/Hammunition/reference/cli/ . Every --json output document, field by field: https://renegade-penguin.github.io/Hammunition/reference/json-interface/ (generated from the engine's own dataclasses by scripts/gen_json_reference.py; a test fails the build when page and code disagree). The input format, the catalog manifest schema: src/hammunition/manifest/schema.py and https://renegade-penguin.github.io/Hammunition/contributing/manifests/


  • Other


    Enough for a badge!

    The project sites (website, repository, and download URLs) MUST support HTTPS using TLS. [sites_https]
    This requires that the project home page URL and the version control repository URL begin with "https:", not "http:". You can get free certificates from Let's Encrypt. Projects MAY implement this criterion using (for example) GitHub pages, GitLab pages, or SourceForge project pages. If you support HTTP, we urge you to redirect the HTTP traffic to HTTPS.

    Site, repository and release downloads are HTTPS only; GitHub Pages enforces HTTPS.


    Enough for a badge!

    The project MUST have one or more mechanisms for discussion (including proposed changes and issues) that are searchable, allow messages and topics to be addressed by URL, enable new people to participate in some of the discussions, and do not require client-side installation of proprietary software. [discussion]
    Examples of acceptable mechanisms include archived mailing list(s), GitHub issue and pull request discussions, Bugzilla, Mantis, and Trac. Asynchronous discussion mechanisms (like IRC) are acceptable if they meet these criteria; make sure there is a URL-addressable archiving mechanism. Proprietary JavaScript, while discouraged, is permitted.

    GitHub issues and pull requests: searchable, URL-addressable, open to anyone with an account, no proprietary client. https://github.com/Renegade-Penguin/Hammunition/issues


    Enough for a badge!

    The project SHOULD provide documentation in English and be able to accept bug reports and comments about code in English. [english]
    English is currently the lingua franca of computer technology; supporting English increases the number of different potential developers and reviewers worldwide. A project can meet this criterion even if its core developers' primary language is not English.

    All documentation, issues, commit messages and code comments are in English; bug reports in English are accepted.


    Enough for a badge!

    The project MUST be maintained. [maintained]
    As a minimum, the project should attempt to respond to significant problem and vulnerability reports. A project that is actively pursuing a badge is probably maintained. All projects and people have limited resources, and typical projects must reject some proposed changes, so limited resources and proposal rejections do not by themselves indicate an unmaintained project.

    When a project knows that it will no longer be maintained, it should set this criterion to "Unmet" and use the appropriate mechanism(s) to indicate to others that it is not being maintained. For example, use “DEPRECATED” as the first heading of its README, add “DEPRECATED” near the beginning of its home page, add “DEPRECATED” to the beginning of its code repository project description, add a no-maintenance-intended badge in its README and/or home page, mark it as deprecated in any package repositories (e.g., npm deprecate), and/or use the code repository's marking system to archive it (e.g., GitHub's "archive" setting, GitLab’s "archived" marking, Gerrit's "readonly" status, or SourceForge’s "abandoned" project status). Additional discussion can be found here.

    Active daily development: v0.21.0 released 2026-10-04, the organisation move 2026-10-05, and a public project board showing current work at https://github.com/orgs/Renegade-Penguin/projects/1 . Issues are triaged and answered by the maintainer.


 Change Control 9/9 ●

  • Public version-controlled source repository


    Enough for a badge!

    The project MUST have a version-controlled source repository that is publicly readable and has a URL. [repo_public]
    The URL MAY be the same as the project URL. The project MAY use private (non-public) branches in specific cases while the change is not publicly released (e.g., for fixing a vulnerability before it is revealed to the public).

    Repository on GitHub, which provides public git repositories with URLs.


    Enough for a badge!

    The project's source repository MUST track what changes were made, who made the changes, and when the changes were made. [repo_track]

    Repository on GitHub, which uses git. git can track the changes, who made them, and when they were made.


    Enough for a badge!

    To enable collaborative review, the project's source repository MUST include interim versions for review between releases; it MUST NOT include only final releases. [repo_interim]
    Projects MAY choose to omit specific interim versions from their public source repositories (e.g., ones that fix specific non-public security vulnerabilities, may never be publicly released, or include material that cannot be legally posted and are not in the final release).

    Every change reaches main by pull request between releases; the history holds every interim commit, not only tagged releases. https://github.com/Renegade-Penguin/Hammunition/commits/main and https://github.com/Renegade-Penguin/Hammunition/pulls?q=is%3Apr+is%3Amerged


    Enough for a badge!

    It is SUGGESTED that common distributed version control software be used (e.g., git) for the project's source repository. [repo_distributed]
    Git is not specifically required and projects can use centralized version control software (such as subversion) with justification.

    Repository on GitHub, which uses git. git is distributed.


  • Unique version numbering


    Enough for a badge!

    The project results MUST have a unique version identifier for each release intended to be used by users. [version_unique]
    This MAY be met in a variety of ways including a commit IDs (such as git commit id or mercurial changeset id) or a version number (including version numbers that use semantic versioning or date-based schemes like YYYYMMDD).

    Semantic versions on annotated git tags (v0.21.0 current); pyproject.toml carries the same version and a release check refuses a tag whose version disagrees with it. https://github.com/Renegade-Penguin/Hammunition/tags


    Enough for a badge!

    It is SUGGESTED that the Semantic Versioning (SemVer) or Calendar Versioning (CalVer) version numbering format be used for releases. It is SUGGESTED that those who use CalVer include a micro level value. [version_semver]
    Projects should generally prefer whatever format is expected by their users, e.g., because it is the normal format used by their ecosystem. Many ecosystems prefer SemVer, and SemVer is generally preferred for application programmer interfaces (APIs) and software development kits (SDKs). CalVer tends to be used by projects that are large, have an unusually large number of independently-developed dependencies, have a constantly-changing scope, or are time-sensitive. It is SUGGESTED that those who use CalVer include a micro level value, because including a micro level supports simultaneously-maintained branches whenever that becomes necessary. Other version numbering formats may be used as version numbers, including git commit IDs or mercurial changeset IDs, as long as they uniquely identify versions. However, some alternatives (such as git commit IDs) can cause problems as release identifiers, because users may not be able to easily determine if they are up-to-date. The version ID format may be unimportant for identifying software releases if all recipients only run the latest version (e.g., it is the code for a single website or internet service that is constantly updated via continuous delivery).

    Enough for a badge!

    It is SUGGESTED that projects identify each release within their version control system. For example, it is SUGGESTED that those using git identify each release using git tags. [version_tags]

    Each release is an annotated git tag v<version>; a repository ruleset makes v* tags immutable (no deletion, no force-push). https://github.com/Renegade-Penguin/Hammunition/tags


  • Release notes


    Enough for a badge!

    The project MUST provide, in each release, release notes that are a human-readable summary of major changes in that release to help users determine if they should upgrade and what the upgrade impact will be. The release notes MUST NOT be the raw output of a version control log (e.g., the "git log" command results are not release notes). Projects whose results are not intended for reuse in multiple locations (such as the software for a single website or service) AND employ continuous delivery MAY select "N/A". (URL required) [release_notes]
    The release notes MAY be implemented in a variety of ways. Many projects provide them in a file named "NEWS", "CHANGELOG", or "ChangeLog", optionally with extensions such as ".txt", ".md", or ".html". Historically the term "change log" meant a log of every change, but to meet these criteria what is needed is a human-readable summary. The release notes MAY instead be provided by version control system mechanisms such as the GitHub Releases workflow.

    CHANGELOG.md keeps a human-readable section per release, assembled at release time from per-change fragments (never a git log), and each GitHub release carries the same notes. https://github.com/Renegade-Penguin/Hammunition/blob/main/CHANGELOG.md and https://github.com/Renegade-Penguin/Hammunition/releases


    Enough for a badge!

    The release notes MUST identify every publicly known run-time vulnerability fixed in this release that already had a CVE assignment or similar when the release was created. This criterion may be marked as not applicable (N/A) if users typically cannot practically update the software themselves (e.g., as is often true for kernel updates). This criterion applies only to the project results, not to its dependencies. If there are no release notes or there have been no publicly known vulnerabilities, choose N/A. [release_notes_vulns]
    This criterion helps users determine if a given update will fix a vulnerability that is publicly known, to help users make an informed decision about updating. If users typically cannot practically update the software themselves on their computers, but must instead depend on one or more intermediaries to perform the update (as is often the case for a kernel and low-level software that is intertwined with a kernel), the project may choose "not applicable" (N/A) instead, since this additional information will not be helpful to those users. Similarly, a project may choose N/A if all recipients only run the latest version (e.g., it is the code for a single website or internet service that is constantly updated via continuous delivery). This criterion only applies to the project results, not its dependencies. Listing the vulnerabilities of all transitive dependencies of a project becomes unwieldy as dependencies increase and vary, and is unnecessary since tools that examine and track dependencies can do this in a more scalable way.

    No vulnerability with a CVE or equivalent has been reported against the project to date. When one is, the release that fixes it names it in CHANGELOG.md and the release notes.


 Reporting 8/8 ●

  • Bug-reporting process


    Enough for a badge!

    The project MUST provide a process for users to submit bug reports (e.g., using an issue tracker or a mailing list). (URL required) [report_process]

    Bugs and enhancements: https://github.com/Renegade-Penguin/Hammunition/issues (CONTRIBUTING.md says so). Vulnerabilities: https://github.com/Renegade-Penguin/Hammunition/security/policy


    Enough for a badge!

    The project SHOULD use an issue tracker for tracking individual issues. [report_tracker]

    GitHub issues, one issue per problem; every issue and pull request is also carded on the project board https://github.com/orgs/Renegade-Penguin/projects/1


    Enough for a badge!

    The project MUST acknowledge a majority of bug reports submitted in the last 2-12 months (inclusive); the response need not include a fix. [report_responses]

    Every bug report in the tracker's history has been acknowledged and triaged by the maintainer (labelled, carded on the board, fixed or answered). https://github.com/Renegade-Penguin/Hammunition/issues?q=is%3Aissue


    Enough for a badge!

    The project SHOULD respond to a majority (>50%) of enhancement requests in the last 2-12 months (inclusive). [enhancement_responses]
    The response MAY be 'no' or a discussion about its merits. The goal is simply that there be some response to some requests, which indicates that the project is still alive. For purposes of this criterion, projects need not count fake requests (e.g., from spammers or automated systems). If a project is no longer making enhancements, please select "unmet" and include the URL that makes this situation clear to users. If a project tends to be overwhelmed by the number of enhancement requests, please select "unmet" and explain.

    Enhancement requests receive a response: accepted onto the board with a priority, deferred with a reason, or declined with the reasoning recorded in docs/DECISIONS.md. https://github.com/Renegade-Penguin/Hammunition/issues?q=is%3Aissue


    Enough for a badge!

    The project MUST have a publicly available archive for reports and responses for later searching. (URL required) [report_archive]

    https://github.com/Renegade-Penguin/Hammunition/issues?q=is%3Aissue (open and closed, searchable) and https://github.com/Renegade-Penguin/Hammunition/pulls?q=is%3Apr for review discussions.


  • Vulnerability report process


    Enough for a badge!

    The project MUST publish the process for reporting vulnerabilities on the project site. (URL required) [vulnerability_report_process]
    Projects hosted on GitHub SHOULD consider enabling privately reporting a security vulnerability. Projects on GitLab SHOULD consider using its ability for privately reporting a vulnerability. Projects MAY identify a mailing address on https://PROJECTSITE/security, often in the form security@example.org. This vulnerability reporting process MAY be the same as its bug reporting process. Vulnerability reports MAY always be public, but many projects have a private vulnerability reporting mechanism.

    https://github.com/Renegade-Penguin/Hammunition/security/policy (SECURITY.md): how to report privately, what to include, what is in scope, what to expect.


    Enough for a badge!

    If private vulnerability reports are supported, the project MUST include how to send the information in a way that is kept private. (URL required) [vulnerability_report_private]
    Examples include a private defect report submitted on the web using HTTPS (TLS) or an email encrypted using OpenPGP. If vulnerability reports are always public (so there are never private vulnerability reports), choose "not applicable" (N/A).

    GitHub private vulnerability reporting is enabled and is the published channel: https://github.com/Renegade-Penguin/Hammunition/security/advisories/new (HTTPS, visible only to the maintainer until disclosure). SECURITY.md asks reporters to use it and never a public issue.


    Enough for a badge!

    The project's initial response time for any vulnerability report received in the last 6 months MUST be less than or equal to 14 days. [vulnerability_report_response]
    If there have been no vulnerabilities reported in the last 6 months, choose "not applicable" (N/A).

    No vulnerability report has been received in the last 6 months. SECURITY.md commits to an acknowledgement within a week, inside the 14-day bound.


 Quality 13/13 ●

  • Working build system


    Enough for a badge!

    If the software produced by the project requires building for use, the project MUST provide a working build system that can automatically rebuild the software from source code. [build]
    A build system determines what actions need to occur to rebuild the software (and in what order), and then performs those steps. For example, it can invoke a compiler to compile the source code. If an executable is created from source code, it must be possible to modify the project's source code and then generate an updated executable with those modifications. If the software produced by the project depends on external libraries, the build system does not need to build those external libraries. If there is no need to build anything to use the software after its source code is modified, select "not applicable" (N/A).

    pip install . builds and installs the engine from pyproject.toml; the Makefile wraps the developer workflow (make venv, make test, make types, make lint, make docs, make check). The catalog is data and needs no build. https://github.com/Renegade-Penguin/Hammunition/blob/main/Makefile


    Enough for a badge!

    It is SUGGESTED that common tools be used for building the software. [build_common_tools]
    For example, Maven, Ant, cmake, the autotools, make, rake (Ruby), or devtools (R).

    Standard Python packaging (pyproject.toml, pip, setuptools) and GNU make.


    Enough for a badge!

    The project SHOULD be buildable using only FLOSS tools. [build_floss_tools]

    Python 3.11+, pip, setuptools, GNU make, MkDocs for the site. No proprietary tool anywhere in the build, the tests or the documentation.


  • Automated test suite


    Enough for a badge!

    The project MUST use at least one automated test suite that is publicly released as FLOSS (this test suite may be maintained as a separate FLOSS project). The project MUST clearly show or document how to run the test suite(s) (e.g., via a continuous integration (CI) script or via documentation in files such as BUILD.md, README.md, or CONTRIBUTING.md). [test]
    The project MAY use multiple automated test suites (e.g., one that runs quickly, vs. another that is more thorough but requires special equipment). There are many test frameworks and test support systems available, including Selenium (web browser automation), Junit (JVM, Java), RUnit (R), testthat (R).

    A pytest suite under tests/, released under the project licence, run by CI on every pull request and push, and in containers for seven target distributions (Parrot, Debian 13, Debian 13 arm64, Kali, Linux Mint, Ubuntu 24.04, Ubuntu 26.04). How to run it: make test (or pytest) per CONTRIBUTING.md and https://renegade-penguin.github.io/Hammunition/contributing/ci/ ; make containers (scripts/run-targets.sh) runs the container matrix locally with rootless Podman.


    Enough for a badge!

    A test suite SHOULD be invocable in a standard way for that language. [test_invocation]
    For example, "make check", "mvn test", or "rake test" (Ruby).

    make check runs everything CI runs except the containers (lint, types, tests, docs); make test and plain pytest run the suite. https://github.com/Renegade-Penguin/Hammunition/blob/main/Makefile


    Enough for a badge!

    It is SUGGESTED that the test suite cover most (or ideally all) the code branches, input fields, and functionality. [test_most]

    The suite covers every CLI verb and every JSON document (the JSON reference is generated from the code and tested against it), every install backend (apt, source, git, binary, venv, node, apt_repo, data) with each one VM-verified, the manifest schema and every manifest in the catalog, the hardware catalog, every generated document (each generator has a --check the tests run), repository hygiene, licensing headers and the site build. Parsers are additionally fuzzed with Atheris under fuzz/.


    Enough for a badge!

    It is SUGGESTED that the project implement continuous integration (where new or changed code is frequently integrated into a central code repository and automated tests are run on the result). [test_continuous_integration]

    GitHub Actions on every pull request and push to main through the shared reusable workflows at https://github.com/ChiefGyk3D/git-your-ship-together ; CI green plus the seven container jobs, the docs link check, repository hygiene, the site build and the fuzz job are required checks on main.


  • New functionality testing


    Enough for a badge!

    The project MUST have a general policy (formal or not) that as major new functionality is added to the software produced by the project, tests of that functionality should be added to an automated test suite. [test_policy]
    As long as a policy is in place, even by word of mouth, that says developers should add tests to the automated test suite for major new functionality, select "Met."

    Written policy: "Every project here gets working CI and a real test suite, and their absence is a defect to fix" (CLAUDE.md, section "CI and tests are not optional"). CONTRIBUTING.md requires tests to pass in the target containers before a pull request is opened and a changelog fragment for every change to src/, catalog/ or docs/guides/.


    Enough for a badge!

    The project MUST have evidence that the test_policy for adding tests has been adhered to in the most recent major changes to the software produced by the project. [tests_are_added]
    Major functionality would typically be mentioned in the release notes. Perfection is not required, merely evidence that tests are typically being added in practice to the automated test suite when new major functionality is added to the software produced by the project.

    v0.21.0 (2026-10-04) shipped 28 changes, each with tests (CHANGELOG.md). The fuzzing rollout found 14 parser bugs across the suite and each fix landed with a regression test (for example the station list values fix, Hammunition #341). https://github.com/Renegade-Penguin/Hammunition/pulls?q=is%3Apr+is%3Amerged


    Enough for a badge!

    It is SUGGESTED that this policy on adding tests (see test_policy) be documented in the instructions for change proposals. [tests_documented_added]
    However, even an informal rule is acceptable as long as the tests are being added in practice.

    CONTRIBUTING.md "Before you open a pull request" and CLAUDE.md "CI and tests are not optional" ("Put checks in the test suite; let CI run the test suite", "A check must be falsifiable").


  • Warning flags


    Enough for a badge!

    The project MUST enable one or more compiler warning flags, a "safe" language mode, or use a separate "linter" tool to look for code quality errors or common simple mistakes, if there is at least one FLOSS tool that can implement this criterion in the selected language. [warnings]
    Examples of compiler warning flags include gcc/clang "-Wall". Examples of a "safe" language mode include JavaScript "use strict" and perl5's "use warnings". A separate "linter" tool is simply a tool that examines the source code to look for code quality errors or common simple mistakes. These are typically enabled within the source code or build instructions.

    ruff (rule sets E, F, W, I, UP, B, SIM, ANN, RUF) and mypy --strict, both CI gates, configured in pyproject.toml; shellcheck on the shell scripts through the shared bash-ci workflow.


    Enough for a badge!

    The project MUST address warnings. [warnings_fixed]
    These are the warnings identified by the implementation of the warnings criterion. The project should fix warnings or mark them in the source code as false positives. Ideally there would be no warnings, but a project MAY accept some warnings (typically less than 1 warning per 100 lines or less than 10 warnings).

    Zero warnings: ruff check, ruff format --check and mypy --strict must all pass for CI green, which is a required check on main.


    Enough for a badge!

    It is SUGGESTED that projects be maximally strict with warnings in the software produced by the project, where practical. [warnings_strict]
    Some warnings cannot be effectively enabled on some projects. What is needed is evidence that the project is striving to enable warning flags where it can, so that errors are detected early.

    mypy --strict across src/, scripts/ and tests/; ruff with bugbear, simplify, annotations and pyupgrade rule sets on top of the defaults.


 Security 16/16 ●

  • Secure development knowledge


    Enough for a badge!

    The project MUST have at least one primary developer who knows how to design secure software. (See ‘details’ for the exact requirements.) [know_secure_design]
    This requires understanding the following design principles, including the 8 principles from Saltzer and Schroeder:
    • economy of mechanism (keep the design as simple and small as practical, e.g., by adopting sweeping simplifications)
    • fail-safe defaults (access decisions should deny by default, and projects' installation should be secure by default)
    • complete mediation (every access that might be limited must be checked for authority and be non-bypassable)
    • open design (security mechanisms should not depend on attacker ignorance of its design, but instead on more easily protected and changed information like keys and passwords)
    • separation of privilege (ideally, access to important objects should depend on more than one condition, so that defeating one protection system won't enable complete access. E.G., multi-factor authentication, such as requiring both a password and a hardware token, is stronger than single-factor authentication)
    • least privilege (processes should operate with the least privilege necessary)
    • least common mechanism (the design should minimize the mechanisms common to more than one user and depended on by all users, e.g., directories for temporary files)
    • psychological acceptability (the human interface must be designed for ease of use - designing for "least astonishment" can help)
    • limited attack surface (the attack surface - the set of the different points where an attacker can try to enter or extract data - should be limited)
    • input validation with allowlists (inputs should typically be checked to determine if they are valid before they are accepted; this validation should use allowlists (which only accept known-good values), not denylists (which attempt to list known-bad values)).
    A "primary developer" in a project is anyone who is familiar with the project's code base, is comfortable making changes to it, and is acknowledged as such by most other participants in the project. A primary developer would typically make a number of contributions over the past year (via code, documentation, or answering questions). Developers would typically be considered primary developers if they initiated the project (and have not left the project more than three years ago), have the option of receiving information on a private vulnerability reporting channel (if there is one), can accept commits on behalf of the project, or perform final releases of the project software. If there is only one developer, that individual is the primary developer. Many books and courses are available to help you understand how to develop more secure software and discuss design. For example, the Secure Software Development Fundamentals course is a free set of three courses that explain how to develop more secure software (it's free if you audit it; for an extra fee you can earn a certificate to prove you learned the material).

    The primary developer is a working cybersecurity engineer (CISSP) whose profession is defensive security engineering. The design record (docs/DECISIONS.md) applies the principles explicitly: least privilege (root only for apt and udev, everything else as the user; one root helper behind one polkit action); fail-safe defaults (consent gates that --yes cannot satisfy; transmit-capable tooling behind opt-in); complete mediation (every download verified against a pinned sha256 or refused); open design (every system change printed before it is made, and recorded in a transaction log); economy of mechanism (apt via subprocess, standard library wherever possible); limited attack surface (services bind loopback only, no inbound ports); allowlist validation (manifest schema, regex-validated device paths, fixed vocabularies).


    Enough for a badge!

    At least one of the project's primary developers MUST know of common kinds of errors that lead to vulnerabilities in this kind of software, as well as at least one method to counter or mitigate each of them. [know_common_errors]
    Examples (depending on the type of software) include SQL injection, OS injection, classic buffer overflow, cross-site scripting, missing authentication, and missing authorization. See the CWE/SANS top 25 or OWASP Top 10 for commonly used lists. Many books and courses are available to help you understand how to develop more secure software and discuss common implementation errors that lead to vulnerabilities. For example, the Secure Software Development Fundamentals course is a free set of three courses that explain how to develop more secure software (it's free if you audit it; for an extra fee you can earn a certificate to prove you learned the material).

    The developer knows the CWE/SANS Top 25 and OWASP Top 10 classes relevant to this software (OS command injection, path traversal, unsafe deserialisation, TOCTOU on files, supply-chain substitution, privilege escalation through helpers) and the project mitigates each by design: subprocess argv lists with no shell, paths validated against fixed roots, YAML loaded safely, atomic root-owned writes under a lock, a privileged helper that takes no unit as an argument, and no unverified download anywhere. CodeQL, Semgrep and Snyk Code findings are triaged with written reasons; zero open.


  • Use basic good cryptographic practices

    Note that some software does not need to use cryptographic mechanisms. If your project produces software that (1) includes, activates, or enables encryption functionality, and (2) might be released from the United States (US) to outside the US or to a non-US-citizen, you may be legally required to take a few extra steps. Typically this just involves sending an email. For more information, see the encryption section of Understanding Open Source Technology & US Export Controls.

    Enough for a badge!

    The software produced by the project MUST use, by default, only cryptographic protocols and algorithms that are publicly published and reviewed by experts (if cryptographic protocols and algorithms are used). [crypto_published]
    These cryptographic criteria do not always apply because some software has no need to directly use cryptographic capabilities.

    Only standard primitives through standard libraries: SHA-256 (hashlib) for every download and artefact check; TLS from the platform OpenSSL for every fetch; OpenPGP key fingerprints parsed per RFC 4880 to pin third-party apt signing keys; Sigstore (Fulcio and Rekor) for release signatures. Nothing is invented.


    Enough for a badge!

    If the software produced by the project is an application or library, and its primary purpose is not to implement cryptography, then it SHOULD only call on software specifically designed to implement cryptographic functions; it SHOULD NOT re-implement its own. [crypto_call]

    The project implements no cryptography; it calls hashlib, the platform TLS stack and Sigstore tooling.


    Enough for a badge!

    All functionality in the software produced by the project that depends on cryptography MUST be implementable using FLOSS. [crypto_floss]
    See the Open Standards Requirement for Software by the Open Source Initiative.

    All of it is implementable with FLOSS (OpenSSL, Python's hashlib, Sigstore).


    Enough for a badge!

    The security mechanisms within the software produced by the project MUST use default keylengths that at least meet the NIST minimum requirements through the year 2030 (as stated in 2012). It MUST be possible to configure the software so that smaller keylengths are completely disabled. [crypto_keylength]
    These minimum bitlengths are: symmetric key 112, factoring modulus 2048, discrete logarithm key 224, discrete logarithmic group 2048, elliptic curve 224, and hash 224 (password hashing is not covered by this bitlength, more information on password hashing can be found in the crypto_password_storage criterion). See https://www.keylength.com for a comparison of keylength recommendations from various organizations. The software MAY allow smaller keylengths in some configurations (ideally it would not, since this allows downgrade attacks, but shorter keylengths are sometimes necessary for interoperability).

    Hashes are SHA-256 (256 bits, above the 224 minimum). The project holds no keys of its own; third-party apt keys are the distribution's or vendor's and are pinned by full fingerprint, never generated or shortened.


    Enough for a badge!

    The default security mechanisms within the software produced by the project MUST NOT depend on broken cryptographic algorithms (e.g., MD4, MD5, single DES, RC4, Dual_EC_DRBG), or use cipher modes that are inappropriate to the context, unless they are necessary to implement an interoperable protocol (where the protocol implemented is the most recent version of that standard broadly supported by the network ecosystem, that ecosystem requires the use of such an algorithm or mode, and that ecosystem does not offer any more secure alternative). The documentation MUST describe any relevant security risks and any known mitigations if these broken algorithms or modes are necessary for an interoperable protocol. [crypto_working]
    ECB mode is almost never appropriate because it reveals identical blocks within the ciphertext as demonstrated by the ECB penguin, and CTR mode is often inappropriate because it does not perform authentication and causes duplicates if the input state is repeated. In many cases it's best to choose a block cipher algorithm mode designed to combine secrecy and authentication, e.g., Galois/Counter Mode (GCM) and EAX. Projects MAY allow users to enable broken mechanisms (e.g., during configuration) where necessary for compatibility, but then users know they're doing it.

    No broken algorithm is used by default. SHA-1 appears in one place: computing an OpenPGP v4 key fingerprint, which RFC 4880 defines as SHA-1 (an interoperable protocol); it identifies a key the operator typed, and the integrity of what is installed rests on the distribution's signatures and SHA-256 checks, not on that identifier. Documented in docs/DECISIONS.md (D-040).


    Enough for a badge!

    The default security mechanisms within the software produced by the project SHOULD NOT depend on cryptographic algorithms or modes with known serious weaknesses (e.g., the SHA-1 cryptographic hash algorithm or the CBC mode in SSH). [crypto_weaknesses]
    Concerns about CBC mode in SSH are discussed in CERT: SSH CBC vulnerability.

    As above: the only SHA-1 is the RFC 4880 v4 fingerprint format, used as a key identifier. No CBC-in-SSH or similar; TLS is the platform's.


    Enough for a badge!

    The security mechanisms within the software produced by the project SHOULD implement perfect forward secrecy for key agreement protocols so a session key derived from a set of long-term keys cannot be compromised if one of the long-term keys is compromised in the future. [crypto_pfs]

    The project implements no key agreement protocol; TLS is provided by the platform stack.


    Enough for a badge!

    If the software produced by the project causes the storing of passwords for authentication of external users, the passwords MUST be stored as iterated hashes with a per-user salt by using a key stretching (iterated) algorithm (e.g., Argon2id, Bcrypt, Scrypt, or PBKDF2). See also OWASP Password Storage Cheat Sheet. [crypto_password_storage]
    This criterion applies only when the software is enforcing authentication of users using passwords for external users (aka inbound authentication), such as server-side web applications. It does not apply in cases where the software stores passwords for authenticating into other systems (aka outbound authentication, e.g., the software implements a client for some other system), since at least parts of that software must have often access to the unhashed password.

    The software authenticates no external users and stores no passwords.


    Enough for a badge!

    The security mechanisms within the software produced by the project MUST generate all cryptographic keys and nonces using a cryptographically secure random number generator, and MUST NOT do so using generators that are cryptographically insecure. [crypto_random]
    A cryptographically secure random number generator may be a hardware random number generator, or it may be a cryptographically secure pseudo-random number generator (CSPRNG) using an algorithm such as Hash_DRBG, HMAC_DRBG, CTR_DRBG, Yarrow, or Fortuna. Examples of calls to secure random number generators include Java's java.security.SecureRandom and JavaScript's window.crypto.getRandomValues. Examples of calls to insecure random number generators include Java's java.util.Random and JavaScript's Math.random.

    The software generates no cryptographic keys or nonces.


  • Secured delivery against man-in-the-middle (MITM) attacks


    Enough for a badge!

    The project MUST use a delivery mechanism that counters MITM attacks. Using https or ssh+scp is acceptable. [delivery_mitm]
    An even stronger mechanism is releasing the software with digitally signed packages, since that mitigates attacks on the distribution system, but this only works if the users can be confident that the public keys for signatures are correct and if the users will actually check the signature.

    All downloads are over HTTPS; every non-apt artefact is verified against a sha256 pinned in the catalog (held in git, not fetched) and refused when absent; apt packages are verified by the distribution's signatures; release assets carry SHA256SUMS and Sigstore bundles. https://github.com/Renegade-Penguin/Hammunition/releases


    Enough for a badge!

    A cryptographic hash (e.g., a sha1sum) MUST NOT be retrieved over http and used without checking for a cryptographic signature. [delivery_unsigned]
    These hashes can be modified in transit.

    No hash is retrieved over http. Checksums live in the git history (catalog manifests) or in a SHA256SUMS file that is itself Sigstore-signed on every release.


  • Publicly known vulnerabilities fixed


    Enough for a badge!

    There MUST be no unpatched vulnerabilities of medium or higher severity that have been publicly known for more than 60 days. [vulnerabilities_fixed_60_days]
    The vulnerability must be patched and released by the project itself (patches may be developed elsewhere). A vulnerability becomes publicly known (for this purpose) once it has a CVE with publicly released non-paywalled information (reported, for example, in the National Vulnerability Database) or when the project has been informed and the information has been released to the public (possibly by the project). A vulnerability is considered medium or higher severity if its Common Vulnerability Scoring System (CVSS) base qualitative score is medium or higher. In CVSS versions 2.0 through 3.1, this is equivalent to a CVSS score of 4.0 or higher. Projects may use the CVSS score as published in a widely-used vulnerability database (such as the National Vulnerability Database) using the most-recent version of CVSS reported in that database. Projects may instead calculate the severity themselves using the latest version of CVSS at the time of the vulnerability disclosure, if the calculation inputs are publicly revealed once the vulnerability is publicly known. Note: this means that users might be left vulnerable to all attackers worldwide for up to 60 days. This criterion is often much easier to meet than what Google recommends in Rebooting responsible disclosure, because Google recommends that the 60-day period start when the project is notified even if the report is not public. Also note that this badge criterion, like other criteria, applies to the individual project. Some projects are part of larger umbrella organizations or larger projects, possibly in multiple layers, and many projects feed their results to other organizations and projects as part of a potentially-complex supply chain. An individual project often cannot control the rest, but an individual project can work to release a vulnerability patch in a timely way. Therefore, we focus solely on the individual project's response time. Once a patch is available from the individual project, others can determine how to deal with the patch (e.g., they can update to the newer version or they can apply just the patch as a cherry-picked solution).

    No publicly known vulnerability of medium or higher severity is unpatched; none has been reported against the project to date. Dependabot alerts and security updates are enabled.


    Enough for a badge!

    Projects SHOULD fix all critical vulnerabilities rapidly after they are reported. [vulnerabilities_critical_fixed]

    SECURITY.md: acknowledgement within a week and a fix or written assessment as soon as practical; a critical issue is released as soon as its fix is verified.


  • Other security issues


    Enough for a badge!

    The public repositories MUST NOT leak a valid private credential (e.g., a working password or private key) that is intended to limit public access. [no_leaked_credentials]
    A project MAY leak "sample" credentials for testing and unimportant databases, as long as they are not intended to limit public access.

    No credential has ever been committed: gitleaks scans the full history on every push and pull request in CI, GitHub secret scanning with push protection is enabled, and the project's CI holds no long-lived secrets at all (Doppler over OIDC; no GitHub Actions secrets).


 Analysis 8/8 ●

  • Static code analysis


    Enough for a badge!

    At least one static code analysis tool (beyond compiler warnings and "safe" language modes) MUST be applied to any proposed major production release of the software before its release, if there is at least one FLOSS tool that implements this criterion in the selected language. [static_analysis]
    A static code analysis tool examines the software code (as source code, intermediate code, or executable) without executing it with specific inputs. For purposes of this criterion, compiler warnings and "safe" language modes do not count as static code analysis tools (these typically avoid deep analysis because speed is vital). Some static analysis tools focus on detecting generic defects, others focus on finding specific kinds of defects (such as vulnerabilities), and some do a combination. Examples of such static code analysis tools include cppcheck (C, C++), clang static analyzer (C, C++), SpotBugs (Java), FindBugs (Java) (including FindSecurityBugs), PMD (Java), Brakeman (Ruby on Rails), lintr (R), goodpractice (R), Coverity Quality Analyzer, SonarQube, Codacy, and HP Enterprise Fortify Static Code Analyzer. Larger lists of tools can be found in places such as the Wikipedia list of tools for static code analysis, OWASP information on static code analysis, NIST list of source code security analyzers, and Wheeler's list of static analysis tools. If there are no FLOSS static analysis tools available for the implementation language(s) used, you may select 'N/A'.

    CodeQL (Python and Actions), Semgrep and Snyk Code run on every push to main and weekly, so before every release; results land in GitHub code scanning. https://github.com/Renegade-Penguin/Hammunition/security/code-scanning


    Enough for a badge!

    It is SUGGESTED that at least one of the static analysis tools used for the static_analysis criterion include rules or approaches to look for common vulnerabilities in the analyzed language or environment. [static_analysis_common_vulnerabilities]
    Static analysis tools that are specifically designed to look for common vulnerabilities are more likely to find them. That said, using any static tools will typically help find some problems, so we are suggesting but not requiring this for the 'passing' level badge.

    CodeQL's security query suite, Semgrep's security rules and Snyk Code are all vulnerability-oriented analysers.


    Enough for a badge!

    All medium and higher severity exploitable vulnerabilities discovered with static code analysis MUST be fixed in a timely way after they are confirmed. [static_analysis_fixed]
    A vulnerability is considered medium or higher severity if its Common Vulnerability Scoring System (CVSS) base qualitative score is medium or higher. In CVSS versions 2.0 through 3.1, this is equivalent to a CVSS score of 4.0 or higher. Projects may use the CVSS score as published in a widely-used vulnerability database (such as the National Vulnerability Database) using the most-recent version of CVSS reported in that database. Projects may instead calculate the severity themselves using the latest version of CVSS at the time of the vulnerability disclosure, if the calculation inputs are publicly revealed once the vulnerability is publicly known. Note that criterion vulnerabilities_fixed_60_days requires that all such vulnerabilities be fixed within 60 days of being made public.

    Zero open code-scanning alerts; every finding was fixed or dismissed with a written reason (triage 2026-10-03 to 2026-10-05).


    Enough for a badge!

    It is SUGGESTED that static source code analysis occur on every commit or at least daily. [static_analysis_often]

    On every push and pull request, and weekly on a schedule.


  • Dynamic code analysis


    Enough for a badge!

    It is SUGGESTED that at least one dynamic analysis tool be applied to any proposed major production release of the software before its release. [dynamic_analysis]
    A dynamic analysis tool examines the software by executing it with specific inputs. For example, the project MAY use a fuzzing tool (e.g., American Fuzzy Lop) or a web application scanner (e.g., OWASP ZAP or w3af). In some cases the OSS-Fuzz project may be willing to apply fuzz testing to your project. For purposes of this criterion the dynamic analysis tool needs to vary the inputs in some way to look for various kinds of problems or be an automated test suite with at least 80% branch coverage. The Wikipedia page on dynamic analysis and the OWASP page on fuzzing identify some dynamic analysis tools. The analysis tool(s) MAY be focused on looking for security vulnerabilities, but this is not required.

    Coverage-guided fuzzing with Atheris (libFuzzer) runs in CI on every pull request (30 s per target) and weekly (600 s per target) over the parsers (manifests, station file, repeater importers, Maidenhead and NMEA); the rollout found 14 real parser bugs across the suite, all fixed with regression tests. https://github.com/Renegade-Penguin/Hammunition/tree/main/fuzz


    Enough for a badge!

    It is SUGGESTED that if the software produced by the project includes software written using a memory-unsafe language (e.g., C or C++), then at least one dynamic tool (e.g., a fuzzer or web application scanner) be routinely used in combination with a mechanism to detect memory safety problems such as buffer overwrites. If the project does not produce software written in a memory-unsafe language, choose "not applicable" (N/A). [dynamic_analysis_unsafe]
    Examples of mechanisms to detect memory safety problems include Address Sanitizer (ASAN) (available in GCC and LLVM), Memory Sanitizer, and valgrind. Other potentially-used tools include thread sanitizer and undefined behavior sanitizer. Widespread assertions would also work.

    Pure Python; no memory-unsafe language in the project's own software.


    Enough for a badge!

    It is SUGGESTED that the project use a configuration for at least some dynamic analysis (such as testing or fuzzing) which enables many assertions. In many cases these assertions should not be enabled in production builds. [dynamic_analysis_enable_assertions]
    This criterion does not suggest enabling assertions during production; that is entirely up to the project and its users to decide. This criterion's focus is instead to improve fault detection during dynamic analysis before deployment. Enabling assertions in production use is completely different from enabling assertions during dynamic analysis (such as testing). In some cases enabling assertions in production use is extremely unwise (especially in high-integrity components). There are many arguments against enabling assertions in production, e.g., libraries should not crash callers, their presence may cause rejection by app stores, and/or activating an assertion in production may expose private data such as private keys. Beware that in many Linux distributions NDEBUG is not defined, so C/C++ assert() will by default be enabled for production in those environments. It may be important to use a different assertion mechanism or defining NDEBUG for production in those environments.

    The fuzz targets assert the parsers' invariants on every input (what is accepted round-trips; what is refused raises the documented error type) and the test suite runs with assertions on.


    Enough for a badge!

    All medium and higher severity exploitable vulnerabilities discovered with dynamic code analysis MUST be fixed in a timely way after they are confirmed. [dynamic_analysis_fixed]
    If you are not running dynamic code analysis and thus have not found any vulnerabilities in this way, choose "not applicable" (N/A). A vulnerability is considered medium or higher severity if its Common Vulnerability Scoring System (CVSS) base qualitative score is medium or higher. In CVSS versions 2.0 through 3.1, this is equivalent to a CVSS score of 4.0 or higher. Projects may use the CVSS score as published in a widely-used vulnerability database (such as the National Vulnerability Database) using the most-recent version of CVSS reported in that database. Projects may instead calculate the severity themselves using the latest version of CVSS at the time of the vulnerability disclosure, if the calculation inputs are publicly revealed once the vulnerability is publicly known.

    Every fuzz-found defect was fixed in the next release (v0.21.0 and the sibling releases of 2026-10-04 and 05); none was a vulnerability of medium or higher severity, all were parser robustness bugs.
