Where does PGP Universal Gateway Email look for keys with which to encrypt email?
PGP Universal Gateway Email first examines its own directory of keys to determine if it already has a key for an intended recipient. If no key is found locally, PGP Universal Gateway Email then checks to see if the recipient’s company has a directory that can provide the correct key. Failing that, PGP Universal Gateway Email checks the PGP® Global Directory to see if the intended recipient has uploaded his/her public key.
