Thanks to all contributors!

v2.6.2

Compare Source

v2.6.2 resolves GHSA-whqx-f9j3-ch6m.

Changes

• Fix bundle verify path for old bundle/trusted root (GHSA-whqx-f9j3-ch6m) (#​4624)
• bump sigstore deps to resolve build errors (#​4619)

v2.6.1

Compare Source

Bug Fixes

• Partially populate the output of cosign verify when working with new bundles (#​4416)
• Bump sigstore-go, move conformance back to tagged release (#​4426)

v2.6.0

Compare Source

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.

Features

• Add to attest-blob the ability to supply a complete in-toto statement, and add to verify-blob-attestation the ability to verify with just a digest (#​4306)
• Have cosign sign support bundle format (#​4316)
• Add support for SigningConfig for sign-blob/attest-blob, support Rekor v2 (#​4319)
• Add support for SigningConfig in sign/attest (#​4371)
• Support self-managed keys when signing with sigstore-go (#​4368)
• Don't require timestamps when verifying with a key (#​4337)
• Don't load content from TUF if trusted root path is specified (#​4347)
• Add a terminal spinner while signing with sigstore-go (#​4402)
• Require exclusively a SigningConfig or service URLs when signing (#​4403)
• Remove SHA256 assumption in sign-blob/verify-blob (#​4050)
• Bump sigstore-go, support alternative hash algorithms with keys (#​4386)

Breaking API Changes

• sign.SignerFromKeyOpts no longer generates a key. Instead, it returns whether or not the client needs to generate a key, and if so, clients
  should call sign.KeylessSigner. This allows clients to more easily manage key generation.

Bug Fixes

• Verify subject with bundle only when checking claims (#​4320)
• Fixes to cosign sign / verify for the new bundle format (#​4346)

Bug Fixes

• Fix cert verification logic for trusted-root/SCTs (#​4294)
• force when copying the latest image to overwrite (#​4298)
• avoid double-loading trustedroot from file (#​4264)

v2.4.0

Compare Source

v2.4.0 begins the modernization of the Cosign client, which includes:

• Support for the newer Sigstore specification-compliant bundle format

  through a trust root file, instead of many different flags
• Conformance test suite integration to verify signing and verification behavior

In future updates, we'll include:

• General support for the trust root file, instead of only when using the bundle
  format during verification
• Simplification of trust root flags and deprecation of the
  Cosign-specific bundle format
• Bundle support with container signing

We have also moved nightly Cosign container builds to GHCR instead of GCR.

Features

• Add new bundle support to verify-blob and verify-blob-attestation (#​3796)
• Adding protobuf bundle support to sign-blob and attest-blob (#​3752)
• Bump sigstore/sigstore to support email_verified as string or boolean (#​3819)
• Conformance testing for cosign (#​3806)
• move incremental builds per commit to GHCR instead of GCR (#​3808)
• Add support for recording creation timestamp for cosign attest (#​3797)
• Include SCT verification failure details in error message (#​3799)
