history

Project history and usage

gitsign is a Sigstore tool for keyless signing of Git commits and tags. It uses OpenID Connect identities and Sigstore infrastructure instead of long-lived local signing keys.

Project history

The gitsign repository was created in May 2022 under the Sigstore organization. Its README says the tool was heavily inspired by GitHub's smimesign, but substitutes keyless Sigstore signing with a GitHub or other OIDC identity.

Adoption history

gitsign belongs to the broader Sigstore supply-chain security ecosystem alongside Fulcio, Rekor, and Cosign. Its adoption story is tied to the move from personal key management toward short-lived certificates, identity-backed signatures, and transparency-log verification.

How it is used

Practitioners configure Git to use `gitsign` as the `gpg.x509.program`, set `gpg.format` to `x509`, and then sign commits with `git commit -S` or sign tags with `git tag -s`. Verification commonly uses `gitsign verify` so callers can check both cryptographic integrity and certificate identity claims.

Why package nerds care

For package maintainers, gitsign is important because it brings Sigstore's keyless model to Git history rather than only to container images or release artifacts. It packages a security workflow as a Git signing backend with a small CLI surface and a credential-cache helper.

Timeline

2022: Repository created under the Sigstore organization.
2022: Test release published from the new repository.
2020s: Distributed through Homebrew, Debian, MacPorts, Nix, Arch, Scoop, and zypper package channels.

Related projects

gitsign is related to Sigstore, Fulcio, Rekor, Cosign, Git's X.509 signing support, and GitHub's smimesign.

Before unattended agent use, check whether the tool reads plaintext credentials, writes remote state, publishes artifacts, or shells out to plugins.
