What this tool does not promise

A visible signature image is not the same as a cryptographic signature, and long-term trust depends on certificate, revocation and timestamp infrastructure.

Digital signing and signature validation require server processing for certificates, timestamps, and trust checks. The page reports only the verification status supported by the selected workflow.
