... a non-proprietary protocol for encrypting email communication using public key cryptography. It is based on the original PGP (Pretty Good Privacy) software. The OpenPGP protocol defines standard formats for encrypted messages, signatures, and certificates for exchanging public keys....
On a more serious note, a good method is to construct a DFD (Data Flow Diagram) from human to human and then look at all states and state transitions of the data (includes keymat), then construct a thread model table. You may find that the transport and protocol are “secure”. The ...

In the above diagram, if the binding signature of a subkey has been revoked, the revoked binding signature may be removed, leaving only one signature. In a key that has a main key and subkeys, the primary key MUST be a key capable of signing. The subkeys may be keys of any other ...
