meok-attestation-verify

Tiny zero-dependency verifier for MEOK AI Labs compliance attestations.

Pipe a cert on stdin — get VALID or INVALID back. Nothing installed, nothing to configure.

Install

pip install meok-attestation-verify

Verify a cert

# Via stdin
cat cert.json | meok-attestation-verify

# Via file
meok-attestation-verify cert.json

# Via cert ID only (opens the public verify page)
meok-attestation-verify MEOK-DORA-C8992DC765D8

Exit code 0 = valid, 1 = invalid/expired, 2 = malformed input, 3 = network error.

Why does this exist?

MEOK AI Labs issues HMAC-signed attestations for EU compliance frameworks (DORA, NIS2, CRA, EU AI Act, CSRD, AI-BOM, geospatial data provenance). Each cert carries:

  • cert_id — unique identifier
  • payload — canonical signed JSON
  • signature_sha256_hmac — cryptographic binding
  • verify_url — public verify page

Auditors, boards, and procurement teams can verify a cert without contacting MEOK by POSTing the cert to the public verify endpoint at https://meok-attestation-api.vercel.app/verify.

This CLI wraps that verify flow for humans and CI pipelines.
