DES加密算法及详细说明（HTM）

密码学文献有一个奇妙的发展历程，当然，密而不宣总是扮演主要角色。第一次世界大战前，重要的密码学进展很少出现在公开文献中，但该领域却和其它专业学科一样向前发展。-cryptography literature has a wonderful history, of course, close does not declare always played the leading role. Before the First World War, it was important to cryptography little progress emerged in the open literature. However, the area has other professional disciplines and the development of the same.

rc5 and des encryption and decryption

md5 算法的纯c版本。方便移植到各种嵌入式小型设备不支持c++的环境-md5 algorithm with pure C version. Easy to transplant it to systems using only C, but not C++

采用高级加密标准aes算法针对流媒体加密程序-Using the Advanced Encryption Standard algorithm aes encryption for streaming media

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

几个密码算法的源代码，不知道有了没有~~ 下的人多了就继续上传-Some source programs of encryption arithmetic.I don t know whether it is always existed or not.I will upload it if a lot of people have downloaded.
