Api Endpoint

sicher.halowerk.com

Runs the pinned OpenSSL build's parameter checks over a supplied finite-field Diffie-Hellman group and reports whether it passes, along with the detail output that says why. The point is to catch parameters that are syntactically fine but cryptographically unsafe before they reach a handshake: a non-prime modulus, a generator of small order, a group below the build's security level.
