PGP -- Pretty Good Privacy

Here's a book that deserves to be on your bookshelf! PGP is the best damn encryption program out there (it's so good that even the Church of Scientology and the FBI can't crack it), but the documentation that comes with the program is confusing and intimidating. If you're new to hacking and you want to protect your files, you may be scared away by the difficult instructions. That's where Simson Garfinkel's excellent book comes in: it's a beginner's guide to PGP that will have you up and running within minutes. It includes pointers on handling your PGP keys, using the Internet PGP keyservers, and even a fascinating history of data encryption and the difficulty of keeping it legal in the face of the Conspiracy.
