Verify checksums file signature

The checksums file provided within the artifacts attached to this release is signed using Cosign with GitHub OIDC. To validate the signature of this file, run the following commands: 

# Download the checksums file, certificate and signature
curl -LO https://github.com/getsops/sops/releases/download/v3.9.0/sops-v3.9.0.checksums.txt
curl -LO https://github.com/getsops/sops/releases/download/v3.9.0/sops-v3.9.0.checksums.pem
curl -LO https://github.com/getsops/sops/releases/download/v3.9.0/sops-v3.9.0.checksums.sig

# Verify the checksums file
cosign verify-blob sops-v3.9.0.checksums.txt \
  --certificate sops-v3.9.0.checksums.pem \
  --signature sops-v3.9.0.checksums.sig \
  --certificate-identity-regexp=https://github.com/getsops \
  --certificate-oidc-issuer=https://token.actions.githubusercontent.com

Verify binary integrity

To verify the integrity of the downloaded binary, you can utilize the checksums file after having validated its signature: 

# Verify the binary using the checksums file
sha256sum -c sops-v3.9.0.checksums.txt --ignore-missing

Verify artifact provenance

The SLSA provenance of the binaries, packages, and SBOMs can be found within the artifacts associated with this release. It is presented through an in-toto link metadata file named sops-v3.9.0.intoto.jsonl. To verify the provenance of an artifact, you can utilize the slsa-verifier tool: 

# Download the metadata file
curl -LO  https://github.com/getsops/sops/releases/download/v3.9.0/sops-v3.9.0.intoto.jsonl

# Verify the provenance of the artifact
slsa-verifier verify-artifact <artifact> \
  --provenance-path sops-v3.9.0.intoto.jsonl \
  --source-uri github.com/getsops/sops \
  --source-tag v3.9.0

Container Images

The sops binaries are also available as container images, based on Debian (slim) and Alpine Linux. The Debian-based container images include any dependencies which may be required to make use of certain key services, such as GnuPG, AWS KMS, Azure Key Vault, and Google Cloud KMS. The Alpine-based container images are smaller in size, but do not include these dependencies.

These container images are available for the following architectures: linux/amd64 and linux/arm64.

GitHub Container Registry

  • ghcr.io/getsops/sops:v3.9.0

Verify container image signature

The container images are signed using Cosign with GitHub OIDC. To validate the signature of an image, run the following command: 

cosign verify ghcr.io/getsops/sops:v3.9.0 \
  --certificate-identity-regexp=https://github.com/getsops \
  --certificate-oidc-issuer=https://token.actions.githubusercontent.com \
  -o text

Verify container image provenance

The container images include SLSA provenance attestations. For more information around the verification of this, please refer to the slsa-verifier documentation.
