PGP 是一种混合密码系统。当用户使用PGP 来对纯文字加密的时候， PGP 首先会压缩这 段纯文字。数据压缩能够节省调制解调器传输时间以及磁盘类空间，还有更重要的、强化密码法的 保密程度。-PGP is a hybrid cryptosystem. When the user to use PGP to encrypt the text, PGP will first this text compression. Data compression can save time and modem transmission disk space, and more importantly, to strengthen the password confidentiality law.
