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 baseline badge status on your project page! The baseline badge status looks like this: Baseline badge level for project 12767 is baseline-3 Here is how to embed the baseline badge:

    The README at https://github.com/the-sarge/cpace clearly states: “CPace draft-irtf-cfrg-cpace-21 implementation for the CPACE-RISTR255-SHA512 suite, written in Go. It provides an auditable draft implementation that is not yet production-ready.”

    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.

    Enough for a badge!

    When a CI/CD task is executed with no permissions specified, the CI/CD system MUST default the task's permissions to the lowest permissions granted in the pipeline. [OSPS-AC-04.01]
    Configure the project's settings to assign the lowest available permissions to new pipelines by default, granting additional permissions only when necessary for specific tasks.

    GitHub Actions workflows for this project follow the principle of least privilege. When permissions are not explicitly defined at the job level, the workflows default to the minimum required permissions (read-only where possible). The project’s CI security policy and practices are documented in docs/ci-policy.md.

    When an official release is created, that release MUST be assigned a unique version identifier. [OSPS-BR-02.01]
    Assign a unique version identifier to each release produced by the project, following a consistent naming convention or numbering scheme. Examples include SemVer, CalVer, or git commit id.

    Official releases are created using Git tags with unique version identifiers following semantic versioning (e.g. v0.1.0, v0.2.0). Each release is documented in CHANGELOG.md and follows the release process defined in docs/release-checklist.md.

    When an official release is created, that release MUST contain a descriptive log of functional and security modifications. [OSPS-BR-04.01]
    Ensure that all releases include a descriptive change log. It is recommended to ensure that the change log is human-readable and includes details beyond commit messages, such as descriptions of the security impact or relevance to different use cases. To ensure machine readability, place the content under a markdown header such as "## Changelog".

    When a build and release pipeline ingests dependencies, it MUST use standardized tooling where available. [OSPS-BR-05.01]
    Use a common tooling for your ecosystem, such as package managers or dependency management tools to ingest dependencies at build time. This may include using a dependency file, lock file, or manifest to specify the required dependencies, which are then pulled in by the build system.

    The project uses Go modules as the standardized tooling for ingesting dependencies. All builds, tests, and CI pipelines use the official Go toolchain (go mod, go build, go test, etc.) via go.mod and go.sum.

    Enough for a badge!

    When an official release is created, that release MUST be signed or accounted for in a signed manifest including each asset's cryptographic hashes. [OSPS-BR-06.01]
    Sign all released software assets at build time with a cryptographic signature or attestations, such as GPG or PGP signature, Sigstore signatures, SLSA provenance, or SLSA VSAs. Include the cryptographic hashes of each asset in a signed manifest or metadata file.

    Official releases are signed annotated Git tags, verified with git verify-tag. The project currently publishes no attached binary release assets; future release assets will be signed directly or listed in a signed hash manifest. No binary release assets are attached. Users can verify the release with git verify-tag vX.Y.Z.

    When the project has made a release, the project documentation MUST include a description of how the project selects, obtains, and tracks its dependencies. [OSPS-DO-06.01]
    It is recommended to publish this information alongside the project's technical & design documentation on a publicly viewable resource such as the source code repository, project website, or other channel.

    The project uses Go modules for selecting, obtaining, and tracking dependencies via go.mod and go.sum. The process for reviewing and managing dependencies is documented in docs/dependency-review.md.

    The project documentation MUST include instructions on how to build the software, including required libraries, frameworks, SDKs, and dependencies. [OSPS-DO-07.01]
    It is recommended to publish this information alongside the project's contributor documentation, such as in CONTRIBUTING.md or other developer task documentation. This may also be documented using Makefile targets or other automation scripts.

    Build instructions are provided via Taskfile.yml (commands such as task quick, task check, task check:changed) and the README. The project uses the standard Go toolchain and documents validation steps. Full build documentation will be expanded as the project approaches production readiness.

    While active, the project documentation MUST include a list of project members with access to sensitive resources. [OSPS-GV-01.01]
    Document project participants and their roles through such artifacts as members.md, governance.md, maintainers.md, or similar file within the source code repository of the project. This may be as simple as including names or account handles in a list of maintainers, or more complex depending on the project's governance.

    The project is currently maintained by a single individual (the repository owner the-sarge). This person has administrative access to all sensitive resources (repository settings, secrets, branch protection, etc.). There are no additional project members or collaborators with access to sensitive resources at this time.


    Enough for a badge!

    While active, the project documentation MUST include descriptions of the roles and responsibilities for members of the project. [OSPS-GV-01.02]
    Document project participants and their roles through such artifacts as members.md, governance.md, maintainers.md, or similar file within the source code repository of the project.

    The project is maintained by a single individual who serves as the primary maintainer and owner. Key responsibilities include code development and review, release management, security oversight, dependency management, responding to issues and vulnerability reports, and maintaining project documentation.


    Enough for a badge!

    While active, the project documentation MUST include a guide for code contributors that includes requirements for acceptable contributions. [OSPS-GV-03.02]
    Extend the CONTRIBUTING.md or CONTRIBUTING/ contents in the project documentation to outline the requirements for acceptable contributions, including coding standards, testing requirements, and submission guidelines for code contributors. It is recommended that this guide is the source of truth for both contributors and approvers.

    The project maintains a detailed contributor guide in CONTRIBUTING.md that outlines the contribution process, coding standards, and requirements for acceptable contributions.
    https://github.com/the-sarge/cpace/blob/main/CONTRIBUTING.md


    Enough for a badge!

    While active, the version control system MUST require all code contributors to assert that they are legally authorized to make the associated contributions on every commit. [OSPS-LE-01.01]
    Include a DCO in the project's repository, requiring code contributors to assert that they are legally authorized to commit the associated contributions on every commit. Use a status check to ensure the assertion is made. A CLA also satisfies this requirement. Some version control systems, such as GitHub, may include this in the platform terms of service.

    The project requires DCO signoff for contributions. GitHub web-based commit signoff is enabled, CONTRIBUTING.md documents git commit -s, the repository includes the DCO text, and pull requests are checked by a required DCO GitHub Actions status that verifies every PR commit has a Signed-off-by trailer.

    When a commit is made to the primary branch, any automated status checks for commits MUST pass or be manually bypassed. [OSPS-QA-03.01]
    Configure the project's version control system to require that all automated status checks pass or require manual acknowledgement before a commit can be merged into the primary branch. It is recommended that any optional status checks are NOT configured as a pass or fail requirement that approvers may be tempted to bypass.

    Branch protection rules are enabled on the primary branch (main). All automated status checks from the CI pipeline (including tests and security scans) must pass before changes can be merged to the primary branch. Administrators may manually bypass checks when necessary.

    Enough for a badge!

    Prior to a commit being accepted, the project's CI/CD pipelines MUST run at least one automated test suite to ensure the changes meet expectations. [OSPS-QA-06.01]
    Automated tests should be run prior to every merge into the primary branch. The test suite should be run in a CI/CD pipeline and the results should be visible to all contributors. The test suite should be run in a consistent environment and should be run in a way that allows contributors to run the tests locally. Examples of test suites include unit tests, integration tests, and end-to-end tests.

    The project’s GitHub Actions CI pipeline automatically runs the full test suite (go test ./..., vector tests, fuzz tests, and validation via Taskfile.yml) on every pull request before changes are merged to the primary branch.

    When the project has made a release, the project MUST perform a security assessment to understand the most likely and impactful potential security problems that could occur within the software. [OSPS-SA-03.01]
    Performing a security assessment informs both project members as well as downstream consumers that the project understands what problems could arise within the software. Understanding what threats could be realized helps the project manage and address risk. This information is useful to downstream consumers to demonstrate the security acumen and practices of the project. Ensure this is updated for new features or breaking changes.

    The project has conducted a security assessment, documented in docs/security-assessment.md, which identifies the most likely and impactful potential security problems along with associated mitigations and controls.
