SSH and SSL sound similar, but they're different. Both encrypt their

programming API to do encryption. SSH does not use SSL protocol, but uses
the openssl library for encryption.

PGP and GPG are used for data encryption, not network security. They
use the same underlying algorithms as SSH and SSL.
