RSA算法的实现，大家可以参考看看,用C实现

AES implementation in C++. Input: key file and the file for encryption Output: the crypted file.

JS做的MD5加密算法，可以直接在网页上对您要加密的信息进行MD5加密-JS to do the MD5 encryption algorithm, can be directly on the page you want to encrypt the information MD5 encryption

hash算法的vb实现.很好用!-hash algorithm to achieve the vb. With good!

c加密算法，比较实用的一程序，在别人那拷的.-c encryption algorithm, a more practical procedure, the copy of others.

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
