v1.0.0

Cosign 1.0!

This is the first production ready, non-pre-release version of the cosign tool!

Huge thanks to the entire sigstore community!

Enhancements

• BREAKING: The default HSM key slot is now "signature" instead of "authentication" (#450)
• BREAKING: --fulcio-server is now --fulcio-url (#471)
• Added -cert flag to sign to allow the explicit addition of a signature certificate (#451)
• Added the attest command (#458)
• Added numerous flags for specifying parameters when interacting with Rekor and Fulcio (#462)
• cosign will now send its version string as part of the user-agent when interacting with a container registry (#479)
• Files containing certificates for custom Fulcio endpoints can now be specified via the COSIGN_ROOT environment variable (#477)

Bug Fixes

• Fixed a situation where lower-case as would break verify-dockerfile (Complements to @Dentrax #433)

Verification

The releases are signed using cosign, and can be verified with a previous release or openssl. The key used is currently stored in this repository (at the commit the build was done) in the release/release-cosign.pub file.

Each binary is signed, and the corresponding.sig file is uploaded here. For darwin-amd64, using openssl:

$ openssl dgst -sha256 -verify release/release-cosign.pub -signature <(cat cosign-darwin-amd64.sig | base64 -D) cosign-darwin-amd64
Verified OK

With cosign:

$ cosign verify-blob -key release/release-cosign.pub -signature cosign-darwin-amd64.sig cosign-darwin-amd64
Verified OK
