WebThe certificate process works as follows: 1. First, a client creates a “blank” or unsigned certificate, and sends it to the CA. Included on this blank certificate is the client’s ID. This communication is secured using a D-H private/public key exchange. 2. Next, the CA computes an encrypted hash, which is applied to the blank certificate.
