This article starts out with a nice description of cryptography then goes into how to incorporate PGP for use with Pine. "Encryption is the transformation of data into a form that is (hopefully) impossible to read without the knowledge of a key. Its purpose is to ensure privacy by keeping information hidden from anyone for whom it is not intended. Decryption is the reverse of encryption; it is the transformation of encrypted data back into an intelligible form.

Encryption and decryption generally require the use of some secret information, referred as key. Some encryption mechanisms use the same key for both encryption and decryption; others use different keys for the two processes."
