vc++写的ElGamal加密系统，能够对简单的数字进行加密。(The ElGamal encryption systems, vc++ write simple digital encryption.)

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。

支持加密Sqllite库，vs2008 + sqlite3 + sqlcipher,测试可用(Supports encryption Sqllite library, VS2008+ SQLite3+ sqlcipher, testing available)

用于实现文本串的加密解密功能，程序自带密匙(Text string used to implement the encryption and decryption functions, comes with key program)

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. )
