流密码算法,可用于文件加密和实时通信 ,设计者是著名的密码学家Rivest.该算法效率远高于一般分组密码,并且很适合用于随机数生成-Stream cipher algorithm, can be used for file encryption and real-time communication, the designer is well-known cryptographer Rivest. The algorithm efficiency is much higher than the general block cipher, and is suitable for random number generator

This program encodes and decodes a character using the Vigenere Square method

LaoenED.com/LaoenED.exe for DOS/LaoenED.exe for Windos9x/2k/XP的密码查看器。很小但当你忘了密码的时候很实用！-LaoenED.com/LaoenED.exe for DOS/Windos9x/2k/XP LaoenED.exe for the user. A small, but when you forget the password are very practical!

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

线性移位寄存器是流密码的重要组成部分，该程序就是实现该方法。- The linearity shift register is the stream cipher important constituent, this procedure realizes this method.

RSA的加密代码，含MFC界面，功能强大，可支持任意长度密钥。-RSA" s encryption code with MFC interface, powerful, can support an arbitrary length of the key.
