"Many people have no problems sending sensitive data via e-mail. Most of us do not know how easy it is for anybody to read it. Just because somebody holds the title of "Systems Administrator" does not mean they can be trusted. What is stopping them from reading your e-mail? Nothing. This is where PGP comes in; it is easy-to-use encryption meant for the common person."
"GnuPG is the GNU Privacy Guard. GnuPG is designed to be a free drop-in replacement for PGP (Pretty Good Privacy), created by Phil Zimmermann. PGP is the de facto standard for e-mail security and file encryption on the Internet. It uses public-key cryptography to ensure secure communication between two parties who may have never even met. GnuPG implements the OpenPGP standard as outlined in RFC 2440."
"The purpose of this document is to demonstrate the steps necessary to set up GnuPG and use it with Pine, a popular mail and news client. I will not go into very much detail about the usage and responsability aspects of GnuPG (please refer to the References section for links). I will, however, go into enough detail to ensure that a reader is familiar with the relevant concepts required for sending and receiving PGP signed/encrypted e-mail."
