RSA加密实现，希望对大家有所帮助，研究算法是很让人痛苦的事情，大家多多努力-RSA encryption realize, I hope to be helpful to everyone to study the algorithm is a very painful thing, a lot of U.S. efforts

矛与盾之争（二）——CRC原则部分

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.
