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 14451 is baseline-2 Here is how to embed the baseline badge:
You can show your baseline badge status by embedding this in your markdown file:

    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 defaults new workflows to read-only and Blanc grants write scopes only to jobs that require them. Evidence: https://github.com/bnfy/blanc/blob/main/docs/security-project-safeguards-2026-09-04.md


    Enough for a badge!

    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.

    Every release uses a unique SemVer package version and immutable matching Git tag. Current evidence: https://github.com/bnfy/blanc/releases/tag/v1.17.0


    Enough for a badge!

    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".

    Each GitHub release and repository release note has a human-readable changelog of functional and security-relevant changes. Current note: https://github.com/bnfy/blanc/blob/main/docs/press/release-notes/v1.17.0.md


    Enough for a badge!

    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.

    Blanc uses npm manifests and committed lockfiles; CI and release jobs install with npm ci. Dependency evidence and SBOM generation are documented at https://github.com/bnfy/blanc/blob/main/compliance/README.md


    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.

    v1.17.0 publishes a Sigstore-authenticated SHA256SUMS covering every release asset, plus platform signatures and provenance. Evidence: https://github.com/bnfy/blanc/blob/main/docs/release-incidents/2026-09-13-v1.17.0.md


    Enough for a badge!

    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.

    Committed npm lockfiles select and obtain dependencies; weekly Dependabot proposals track them; policy, SBOM generation, and license review are documented at https://github.com/bnfy/blanc/blob/main/compliance/README.md


    Enough for a badge!

    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.

    Node.js 22, npm ci, local run, build, test, site, dependency, and platform-validation instructions are documented at https://github.com/bnfy/blanc/blob/main/CONTRIBUTING.md


    Enough for a badge!

    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 sole human maintainer and the sensitive project-resource domains they can access are listed at https://github.com/bnfy/blanc/blob/main/docs/governance.md


    Enough for a badge!

    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 maintainer's project, review, security, release, infrastructure, and support responsibilities are documented at https://github.com/bnfy/blanc/blob/main/docs/governance.md


    Enough for a badge!

    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.

    Contribution scope, setup, validation, testing, generated-artifact, PR, review, licensing, and conduct requirements are documented at https://github.com/bnfy/blanc/blob/main/CONTRIBUTING.md


    Enough for a badge!

    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.

    All contributions are made through GitHub. GitHub Terms section D.6 states that each repository contribution is licensed under the repository license and the contributor agrees they have the right to license it. Blanc's contributor guide repeats the authorization requirement. https://docs.github.com/en/site-policy/github-terms/github-terms-of-service#6-contributions-under-repository-license


    Enough for a badge!

    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.

    Protected main requires an up-to-date PR with substrate, acceptance-wiring, oauth-compatibility, and CodeQL javascript checks; admins are included and bypasses remain visible. Evidence: https://github.com/bnfy/blanc/blob/main/docs/security-project-safeguards-2026-09-04.md


    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.

    Required PR CI runs unit, compliance, acceptance-wiring, OAuth compatibility, and CodeQL checks before merge. Contributors can run the same tests locally: https://github.com/bnfy/blanc/blob/main/CONTRIBUTING.md


    Enough for a badge!

    When the project has made a release, the project documentation MUST include design documentation demonstrating all actions and actors within the system. [OSPS-SA-01.01]
    Include designs in the project documentation that explains the actions and actors. Actors include any subsystem or entity that can influence another segment in the system. Ensure this is updated for new features or breaking changes.

    The v1.17.0 security assessment identifies people, untrusted sites, privileged renderers/processes, operating-system integrations, services, and release actors with their actions and trust transitions: https://github.com/bnfy/blanc/blob/main/docs/security-assessment.md


    Enough for a badge!

    When the project has made a release, the project documentation MUST include descriptions of all external software interfaces of the released software assets. [OSPS-SA-02.01]
    Document all software interfaces (APIs) of the released software assets, explaining how users can interact with the software and what data is expected or produced. Ensure this is updated for new features or breaking changes.

    Desktop protocols, local origins, consumed services, Worker HTTP APIs, MCP and companion interfaces, payloads, responses, and data flows are indexed at https://github.com/bnfy/blanc/blob/main/docs/security-assessment.md#released-external-interfaces


    Enough for a badge!

    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 current assessment records likely high-impact threats, existing controls, residual risks, v1.17.0 release evidence, and review triggers: https://github.com/bnfy/blanc/blob/main/docs/security-assessment.md


    Enough for a badge!

    The project documentation MUST include a policy for coordinated vulnerability disclosure (CVD), with a clear timeframe for response. [OSPS-VM-01.01]
    Create a SECURITY.md file at the root of the directory, outlining the project's policy for coordinated vulnerability disclosure. Include a method for reporting vulnerabilities. Set expectations for how the project will respond and address reported issues.

    SECURITY.md defines coordinated private reporting, two-day acknowledgement and five-day assessment targets, severity-based remediation targets, disclosure coordination, and safe harbor: https://github.com/bnfy/blanc/blob/main/SECURITY.md


    Enough for a badge!

    The project documentation MUST provide a means for private vulnerability reporting directly to the security contacts within the project. [OSPS-VM-03.01]
    Provide a means for security researchers to report vulnerabilities privately to the project. This may be a dedicated email address, a web form, VCS specialized tools, email addresses for security contacts, or other methods.

    Security researchers can report privately to support@blanc.day with Security in the subject under https://github.com/bnfy/blanc/blob/main/SECURITY.md


    Enough for a badge!

    The project documentation MUST publicly publish data about discovered vulnerabilities. [OSPS-VM-04.01]
    Provide information about known vulnerabilities in a predictable public channel, such as a CVE entry, blog post, or other medium. To the degree possible, this information should include affected version(s), how a consumer can determine if they are vulnerable, and instructions for mitigation or remediation.

    Confirmed vulnerabilities are published through GitHub Security Advisories and linked or summarized in release notes with affected/fixed versions, impact, and update guidance. Earlier findings are public in the assessment. Policy: https://github.com/bnfy/blanc/blob/main/SECURITY.md#public-vulnerability-record
