说明：  DVD CSS 加密标准解码程序. 支持解开vob文件.(DVD CSS encryption standard decoding procedures. Support untied captures documents.)

说明：  密码学BM算法的C++实现。可计算100阶m序列的生成多项式(Cryptography BM algorithm in C++. Computable 100 m sequence generator polynomial order)

编写的DES 对称加解密技术，可随时进行明文密文之间的转换，有需要的朋友可以下载测试！本人目的打算对后台数据库的敏感信息字段用该方法加密，然后用软件权限控制读取，这样即使直接SQL后台取数，也得不到明文数据。(Write DES symmetrical encryption technology, may at any time for conversion between plaintext cipher, friends in need can be download test! I purpose going to the backstage database of sensitive information field with the method of encryption, and then use software to read access control, so even if the SQL backend access directly, also can not get clear data. )

RSA算法的解密和加密，用扩展的欧几里得算法求乘法逆元(rsa)

des和rsa的算法演示文档 (des and rsa algorithm presentation)

本程序可以在 PE 文件的结尾增加一个新节，从而在已被“加密”的程序开始运行时，要求输入密码。(This procedure can be the end of the document in the PE to add a new section, which has been in the encryption process to start running when asked to enter a password.)

用VC++开发的一款MFC程序，能很好地实现RSA加密和解密算法，对学习RSA加解密算法很有帮助(MFC with VC++ developed a program that can well realize RSA encryption and decryption algorithms, RSA encryption and decryption algorithms for learning helpful)

3des加密解密,des加密解密该算法通过编译，可以直接使用。(3DES encryption and decryption algorithms.)

C++ implementaion for RSA together with the Wiener attack. It uses NTL library for big numbers

Themida的另类破解 附件提供的一个程序是用汇编写的PE信息小工具，用Themida1855加密，加密选择RISC-64 processor，全选加密可选项，并对部分API函数使用VM加密，入口虚拟系数选择15。
