O'Reilly Publishes First Guide to PGP

September 20, 1994 -- SEBASTOPOL, CA--O'Reilly & Associates announces the
November '94 release of PGP: Pretty Good Privacy, the first guide to this
free, widely available, and highly effective encryption program. PGP,
which stands for Pretty Good Privacy, provides protection for files and
electronic mail. Written by Phil Zimmermann and released in 1991, PGP
works on virtually every platform and has become very popular both in the
U.S. and abroad.

Because it uses state-of-the-art public key cryptography, PGP can be used
to authenticate messages, as well as keep them secret. With PGP, you can
digitally "sign" a message when you send it. By checking the digital
signature at the other end, the recipient can be sure that the message was
not changed during transmission and that the message actually came from
you. PGP offers a popular alternative to U.S. government initiatives like
the Clipper Chip because, unlike Clipper, it does not allow the government
or any other outside agency access to your secret keys.

Author Simson Garfinkel has crafted both a readable technical users guide
and a fascinating behind-the-scenes look at cryptography and privacy. Part
I of the book describes how to use PGP: protecting files and email,
creating and using keys, signing messages, certifying and distributing
keys, and using key servers. Part II provides background on cryptography,
battles against public key patents and U.S. government export
restrictions, and other aspects of the ongoing public debates about
privacy and free speech. PGP: Pretty Good Privacy explains how to get PGP
from publicity available sources and how to install it on various
platforms. The book is loaded with actual examples showing how to use
PGP's many features.
