“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.”
