Raktažodžiai:
No, you are not paranoid. They are out to read your email. In this engaging and oddly reassuring text, practitioner Lucas describes Pretty Good Privacy (PGP) and Open Source GPG for moderately skilled computer geeks who are unfamiliar with public-key cryptography but want a cheap solution to security woes. He covers cryptography, installing OPENPGP, installing PGP, installing GNUPG, developing a web of trust, key management, OPENPGP and email, PGP and email, GNUPG and email, and other OPENPGP considerations, and the appendices include an introduction to the PGP command line. Annotation ©2006 Book News, Inc., Portland, OR (booknews.com)

OpenPGP is the most widely used email encryption standard in the world. It is based on PGP (Pretty Good Privacy) as originally developed by Phil Zimmermann. The OpenPGP protocol defines standard formats for encrypted messages, signatures, and certificates for exchanging public keys.

"PGP & GPG" is an easy-to read, informal tutorial for implementing electronic privacy on the cheap using the standard tools of the email privacy field - commercial PGP and non-commercial GnuPG (GPG). The book shows how to integrate these OpenPGP implementations into the most common email clients and how to use PGP and GPG in daily email correspondence to both send and receive encrypted email.

The "PGP & GPG" book is written for the moderately skilled computer user who is unfamiliar with public key cryptography but who is nevertheless interested in guarding their email privacy. Lucas's trademark informal and relaxed tone makes public key cryptography as simple and clear as possible, so that any reasonably savvy computer user can understand it.
