利用RSA加密算法对输入的原文进行加密，输入的可以是主键盘上的任何符号-use RSA encryption algorithm on the importation of the original encrypted input is the main keyboard can be any of the symbols

MD5以512位分组来处理输入的信息，且每一分组又被划分为16个32位子分组，经过了一系列的处理后，算法的输出由四个32位分组组成，将这四个32位分组级联后将生成一个128位散列值。 -MD5 with 512-bit packet to process the input information, and each group was again divided into 16 32-seat group, after a series of processing, the algorithm" s output consists of four 32-bit group composed of these four 32-bit Cascade Group will generate a 128-bit hash value.
