et框架由于拥有CLR提供的丰富库支持，只需很少的代码即可实现先前使用C等旧式语言很难实现的加密算法。本类实现一些常用机密算法，供参考。其中MD5算法返回Int的ToString字串。返回数字字母型结果的算法参见之前Blog文章-* This program is free software you can redistribute it and/or modify it * under the terms of the GNU General Public License as published by the * Free Software Foundation either version 2, or (at your option) any * later version. * * This program is distributed in the hope that it will be useful, * but WITHOUT ANY WARRANTY without even the implied warranty of * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

VHDL implementation of the twofish cipher for 128,192 and 256 bit keys. The implementation is in library-like form All needed components up to, including the round/key schedule circuits are implemented, giving the flexibility to be combined in different architectures (iterative, rolled out/pipelined etc). Manual in English is included with more details about how to use the components and/or how to optimize some of them. All testbenches are provided (tables, variable key/text, ECB/CBC monte carlo) for 128, 192 and 256 bit key sizes, along with their respective vector files.-VHDL implementation of the twofish cipher for 128,192 and 256 bit keys.

这是一个霍夫曼编码程序-This is a Huffman code program

des加密　ElGamal算法既能用于数据加密也能用于数字签名，其安全性依赖于计算有限域上离散对数这一难题。 　　密钥对产生办法。首先选择一个素数p，两个随机数, g 和x，g, x

本程序代码为列队型码，希望对你有一定的帮助，仅供参考！-This procedure code for the line-up code, I hope you have some help, for reference purposes only!

创建巨型文件的参考源代码-create huge document reference source code

数据库安全至关重要，尤其是Access数据库，由于其加密算法过于简单，使得Access单靠密码无法保证其安全，本代码通过改变数据库头文件实现对Acess数据库的加密。-Database security is crucial, especially the Access database, because of its too simple encryption algorithm, making Access a password alone can not guarantee their safety, the code by changing the header file database achieve Acess database encryption.

DES算法BCB组件，有源码，DELPHI也可以用。-DES algorithm BCB components, source code can also be used in Delphi.

这个例子描述了MD4碰撞，很有研究价值，大家可以仔细研究下-MD4碰撞

此算法是用VC++编译的，用RSA算法对任何文件加密，简单易懂。-This algorithm is used VC++ Compiled using RSA algorithm to encrypt any document, easy-to-read.
