✅ Verify a sealed CBOM

Paste a .cbomseal to check its post-quantum signature, integrity and drand timestamp. Free, no account.

A VALID result means the seal was signed by the holder of the stated public key (Dilithium-3, NIST FIPS 204), the declared CBOM hash is intact, and the inventory existed no later than the drand round. It does not audit the inventory and does not certify PQC-readiness or regulatory compliance.
