プロジェクトの歴史

The gittuf repository was opened in 2022, with the project describing itself as a platform-agnostic Git security system. Its README states that repository maintainers can use gittuf to protect repository contents from unauthorized or malicious changes and to avoid making a Git forge the single point of trust.

The first GitHub release, v0.1.0, was published in October 2023. The roadmap shows the project evolving through alpha and beta milestones, policy files, a reference state log, metadata synchronization, and dogfooding of the gittuf repository itself.

The design expanded beyond basic reference protection into supply-chain attestations. The roadmap records in-toto attestation support as reached by April 2024 and describes work on Git forge integration, including a GitHub app that records code-review and merge attestations and reports verification status on pull requests.

採用の歴史

gittuf's adoption story is institutional as well as technical: the README identifies it as an incubating Open Source Security Foundation project in the Supply Chain Integrity Working Group. Packaging across Homebrew, Debian, Nix, and WinGet gives the tool the installation surface expected for security tooling that may be evaluated by teams on different operating systems.

The project sits near Sigstore, gitsign, in-toto, and SLSA in the software supply-chain ecosystem. Its distinguishing role is source-control policy verification that can be checked outside any one forge.

使われ方

A typical workflow starts by generating keys, initializing a Git repository, running `gittuf trust init`, adding policy keys, creating policy rules for protected branches or files, staging and applying policy metadata, and recording reference changes in the reference state log.

Practitioners use `gittuf verify-ref` to check whether a reference follows policy, `gittuf sync` or the `git-remote-gittuf` transport to move gittuf metadata with remote repositories, and manual Git ref pushes or fetches for environments that prefer explicit metadata handling.

パッケージ好きにとっての重要性

gittuf matters to package nerds because it frames source repository state as an input to downstream package trust. It complements artifact signing and provenance by asking whether the Git branch, tag, or file path that produced a package was changed by an authorized identity under an auditable policy.
