microsoft2007的下载密匙。用它来安装。否则无法安装microsoft2007-Key microsoft2007 download. Use it to install. Otherwise it is impossible to install microsoft2007

Motivation - A simple DES core  - Fast and Small Version  - Open Source Compatibility I believe that the core complies to NIST-800-17. However, there has been no formal third party verification. The official NIST specification can be downloaded here: 800-17.pdf. For the Triple DES, the NIST reference is located here: 

自己写的一个Vigenere加密算法．不用多说了吧，值得收藏，特别是对于初学者．-I have written a Vigenere encryption program by myself.Out of question,it is worth to be collection especially by the beginner.

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

RSA算法的实验报告，有源码、流程图、时间复杂度分析等。-RSA algorithm experimental reports, source code, flowcharts, time complexity analysis.

实现移位密码（扩展凯撒密码），用键盘接收明文和密钥，屏幕打印密文。-Achieve translocation password (Extension Caesar password), use the keyboard to receive explicit and key, screen printing ciphertext.

利用DELPHI的INDY来快速制作MD5加密的演示-DELPHI the INDY use to quickly create MD5 encryption demonstration

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
