LZW算法基于转换串表(字典)T,将输入字符串映射成定长(通常为12位)的码字-LZW algorithm is based on converting Series (dictionary) T, the input string mapping into fixed-length (usually 12) the code word

已经通过AES认证的AES的DELPHI实现，比较好，大家自己试试看，搜的-AES has been certified by the AES DELPHI, the better, we all give it a try and found the

des算法，用vc++写出来的，密码学实验写的程序-des algorithm

详细介绍了C函数。

PB使用MD5加密,可以有效解决PB开发中登录密码使用明文的问题-PB using MD5 encryption, can effectively resolve the PB Password development issue of the use of explicit

这是一个完整的数字签名过程，包括密钥的分发管理，摘要的提取，在eclipse上测试成功。

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.
