crc32加密算法，希望对大家有帮助，多多支持-CRC32

1.本程序将所有可能出现的英文和符号定义在ASCII表中的“000--255”中的256个常用字符 2.在实现2的基础上，实现控制台对英文文本文件（注意明文和密文都以文件形式存在）的加解密 形式：cipher 源文件名 目的文件名 密钥 E/D（标示加解密）说明：对于加密来说，源文件名就是明文，对于解密来说，源文件名就是密文-1. This program will all possible symbols in English and in the definition of the ASCII table, "000-- 2 55 "of 256 commonly used characters in two. in achieving two on the basis of Console achieve the English text files (and expressly close attention to the text of a document form) encryption forms : cipher source document file names Key E/D (marked increase declassified) Note : For encryption, source file name is expressly for declassification, the source file name is ciphertext

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.

这是一个加密程序，可对字符串进行加密，字符串和密钥的内容和长度可以设置。-This is an encryption program that encrypt the string, string and key content and length can be set.
