des加密，必须是8位英文字符，或4位中文字符

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.

单报数据加密，在文件传输时对数据报进行加密本程序为服务器端程序。-Single-reported data encryption in the file transfer when the data reported for this procedure to encrypt the server-side program.

一个周期3的多表代替密码，第1个表由密钥字法产生（密钥字自拟），第2个表由洗牌法产生（注意，字母a~z与数字0~25一一对应），第三个表由公式法产生（数学公式自拟，注意它须是Z26上的一个一一变换）-a cycle of three multi-table instead of passwords, a table by key word method, (key word from the intended), Table No. 2 produced by shuffling method (note, a letter with a number of z ~ 0 ~ 25 he gathers), 3rd tables generated by the formula (from the proposed mathematical formula, it should pay attention to the Z26 is a transformation on January 1)
