Cosign digital signature

Detailed information about the digital signature

Summary

Starting with UD2025.38, every CiD (Compiler in Driver) package is digitally signed using the open-source Sigstore Cosign tool.
This guarantees the authenticity and integrity of each release artifact: any modification after signing will invalidate the signature.

Each release asset includes:

<artifact>.sig — the signature file
<artifact>.pem — the signing certificate issued by Sigstore Fulcio

These files allow anyone to independently verify that a given CiD package was produced by the official GitHub Actions workflow for this repository.

Verify the signature online

You can confirm the existence of the public Sigstore record (Rekor transparency log) using the following links:

Linux CiD package:
https://search.sigstore.dev/?hash=sha256:7097f3d12cca491ffcd2418826ac708dbd92a563340a856cd529c1bc0a3cf9d1
Windows CiD package:
https://search.sigstore.dev/?hash=sha256:329ab7e03bafbf4de6e28cae6aaae74216302ba3c702ddde56446e94934ae8db

Verify the signature locally

Install Sigstore Cosign: follow the official installation guide https://docs.sigstore.dev/cosign/system_config/installation
Run Cosign verification

Windows (CMD or PowerShell):

cosign-windows-amd64 verify-blob ^
    --certificate <artifact_name>.pem ^
    --signature <artifact_name>.sig ^
    --certificate-identity https://github.com/openvinotoolkit/npu_compiler/.github/workflows/job_build_cid.yml@refs/tags/npu_ud_2025_38_rc4 ^
    --certificate-oidc-issuer "https://token.actions.githubusercontent.com" ^
    <artifact_name>

Linux / macOS (Bash):

cosign verify-blob \
    --certificate <artifact_name>.pem \
    --signature <artifact_name>.sig \
    --certificate-identity https://github.com/openvinotoolkit/npu_compiler/.github/workflows/job_build_cid.yml@refs/tags/npu_ud_2025_38_rc4 \
    --certificate-oidc-issuer "https://token.actions.githubusercontent.com" \
    <artifact_name>

If the verification succeeds, Cosign prints:

Verified OK

Additional information

Fulcio provides the short-lived signing certificate bound to the official GitHub Actions workflow identity.
Rekor records each signature in an immutable, public transparency log.
Cosign verifies both the cryptographic integrity and the log entry, ensuring that the artifact originates from this repository’s CI pipeline.
