Sigstore

This is a pure Ruby implementation of the sigstore verify command from the sigstore/cosign project. It is intended to be used as a library in other Ruby projects, in additional to a gem subcommand. The project also contains a TUF client implementation, given TUF is a part of the sigstore verification flow.

$ gem sigstore_cosign_verify_bundle --bundle a.txt.sigstore \
    --certificate-identity https://github.com/sigstore-conformance/extremely-dangerous-public-oidc-beacon/.github/workflows/extremely-dangerous-oidc-beacon.yml@refs/heads/main \
    --certificate-oidc-issuer https://token.actions.githubusercontent.com \
