Pretty Good Privacy (PGP), introduced by Phillip Zimmermann in 1991, makes it possible for individuals, groups, and large organizations to protect the contents of E-mail over open paths like the Internet. Keeping in mind that any message sent over the Internet can be read with relatively little effort, PGP has become enormously popular, working on DOS- and MS Windows- based machines as well as with UNIX and Macintosh computers. This is an excellent and thorough technical introduction to PGP-even in the view of PGP's creator. The first third introduces readers to the principles behind PGP. The second part looks at the various editions of PGP for DOS, Macintoshes, and MS Windows. The final section tells you where you can get a copy of PGP, points you to public key servers, helps you figure out a passphrase, and details the encryption behind PGP. If you're considering using PGP and looking for some practical advice, this is the place to find it.
Pretty Good Privacy (PGP) is software that encrypts messages sent by electronic mail, signs messages so that a receiver is guaranteed that the message comes from the alleged sender and not an imposter, and encrypts stored files. It's available for users of DOS, Mac, Windows, and UNIX platforms who want some privacy on the Net. Annotation c. Book News, Inc., Portland, OR (booknews.com)
