md5算法，实现给一个512bir数据块加密，程序有详细的注释，-md5 algorithm, to realize a data block encryption 512bir, procedures have detailed notes,

MD消息摘要程序，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。-MD news summary procedures, MD5 to 512 groups to deal with the importation of information and each group was divided into 16 groups of 32 seats, after a series of processing, the output from the algorithm four groups composed of 32, these four sub-32 will generate a cascade 128 the hash value.
