Summary

  1. Update --check-claims documentation to better describe the behavior of the flag.
  2. Modify verify-blob-attestation to not require a blob argument if --check-claims=false. This file is not used if we're not checking claims - it can be set to anything and still pass.

See https://sigstore.slack.com/archives/C01PZKDL4DP/p1677006107531799 for more discussion.

Release Note

  • verify-blob-attestation will now accept 0 arguments if --check-claims=false is set.
