Api Endpoint

sicher.halowerk.com

Checks a detached OpenPGP signature against the bytes it claims to cover, using the pinned GnuPG build and nothing else. What comes back is the verdict in GnuPG's own terms, the fingerprint that actually signed, the signature timestamp, the algorithms used, and whether the key is expired or revoked. A wrong key, a tampered byte or a signature made by someone else each produce a distinct verdict rather than a bare false.
