v2.6.2

Changelog

v2.6.2 contains a fix for GHSA-whqx-f9j3-ch6m

• 3ade80c5f77cefc904f8c994e88618e5892e8f1c Fix bundle verify path for old bundle/trusted root (#4624)
• c4e6a783ce9b6ad08bb545b79a3277f1aaa16add v2.6 branch - bump sigstore deps (#4619)

Thanks to all contributors!

v2.6.1

Changelog

• 634fabe54f9fbbab55d821a83ba93b2d25bdba5f Bump sigstore-go, move conformance back to tagged release
• c5545eda23d770180880c245bf0d8f78c354ecc4 Partially populate the output of cosign verify when working with new bundles (#4416)
• e191024a636883b4e6b7de8db2f5cfb85a1fcd0c bump go builder to use 1.25.1 and cosign (#4417)

Thanks to all contributors!

v2.6.0 introduces a number of new features, including:

• Signing an in-toto statement rather than Cosign constructing one from a predicate, along with verifying a statement's subject using a digest and digest algorithm rather than providing a file reference (#4306)
• Uploading a signature and its verification material (a "bundle") as an OCI Image 1.1 referring artifact, completing #3927 (#4316)
• Providing service URLs for signing and attesting using a SigningConfig. Note that this is required when using a Rekor v2 instance (#4319)

Example generation and verification of a signed in-toto statement:

cosign attest-blob --new-bundle-format=true --bundle="digest-key-test.sigstore.json" --key="cosign.key" --statement="../sigstore-go/examples/sigstore-go-signing/intoto.txt"
cosign verify-blob-attestation --bundle="digest-key-test.sigstore.json" --key=cosign.pub --type=unused --digest="b94d27b9934d3e08a52e52d7da7dabfac484efe37a5380ee9088f7ace2efcde9" --digestAlg="sha256"

Example container signing and verification using the new bundle format and referring artifacts:

cosign sign --new-bundle-format=true ghcr.io/user/alpine@sha256:a19367999603840546b8612572e338ec076c6d1f2fec61760a9e11410f546733
cosign verify --new-bundle-format=true ghcr.io/user/alpine@sha256:a19367999603840546b8612572e338ec076c6d1f2fec61760a9e11410f546733

Example usage of a signing config provided by the public good instance's TUF repository:

cosign sign-blob --use-signing-config --bundle sigstore.json README.md
cosign verify-blob --new-bundle-format --bundle sigstore.json --certificate-identity $EMAIL --certificate-oidc-issuer $ISSUER --use-signed-timestamps README.md

v2.6.0 leverages sigstore-go's signing and verification APIs gated behind these new flags. In an upcoming major release, we will be updating Cosign to default to producing and consuming bundles to align with all other Sigstore SDKs.
