Signature Verification:
✓ Cryptographically valid — file has not been tampered with
✓ Authentic digital signature
Signature types:
- C2PA Content Credentials: Industry-standard manifest embedded in the file by SignalStamp Cloud.
Trust List Status:
- On trust list: The cloud signing certificate is recognised by compatible third-party verifiers.
- Not on trust list: The signature is cryptographically valid, but its certificate chain is not recognised by that verifier.
Important: Trust list status affects third-party recognition; the signature result separately confirms file integrity.
