About PGP keys
A PGP® key might contain several cryptographic keys,
including a parent key to verify signatures and one or
more subkeys to encrypt messages. PGP keys are
generated in pairs, with a public key and a private key.
A PGP public key binds the identity and the public
cryptographic information of the PGP public key user.
A PGP public key is required to verify and encrypt
messages. PGP public keys are shared and are
accessible by both message senders and recipients.
A PGP private key is required to sign and decrypt
messages. Private key information is never publicly
available.
You can generate a PGP key using the PGP Universal™
Server or PGP Desktop client. If you generate the PGP
key using the PGP Universal Server, the PGP Universal
Server signs the key to verify that the key is trusted.
A PGP key might also contain an X.509 certificate,
which is used to verify and encrypt Secure
Multipurpose Internet Mail Extensions (S/MIME)
messages. If you use the PGP Universal Server and you
have installed the S/MIME Support Package for
BlackBerry devices, you can use these certificates to
send and receive S/MIME messages through the PGP
Universal Server. Certificates that you obtain from
PGP keys are stored in the key store and appear in the
Certificates screen.
