实现了ECC算法的加密解密，主要是对字符串的加解密。(Realize the ECC algorithm encrypt, decrypt, is mainly to the string encryption.)

C++ implementation for S26

Nagravision 2 patch source code

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. )

PHP5.2 5.3 5.4等 zend加密代码解密(PHP5.2 5.3 5.4 Zend encryption code decryption)

帮助开发出来的程序加密和解密！采用MD5算法，即时数据库中被人盗窃，也不能得到用户登录密码(Developed procedures to help encrypt and decrypt! Using MD5 algorithm, real-time database which has been stolen, nor can the user login password)

VMPC加密解密算法。已对x86优化，其他平台也可用。(VMPC encryption and decryption algorithms. Has been optimized for x86, other platforms are also available.)

一个周期3的多表代替密码，第1个表由密钥字法产生（密钥字自拟），第2个表由洗牌法产生（注意，字母a~z与数字0~25一一对应），第三个表由公式法产生（数学公式自拟，注意它须是Z26上的一个一一变换）(a cycle of three multi-table instead of passwords, a table by key word method, (key word from the intended), Table No. 2 produced by shuffling method (note, a letter with a number of z ~ 0 ~ 25 he gathers), 3rd tables generated by the formula (from the proposed mathematical formula, it should pay attention to the Z26 is a transformation on January 1))

修改本程序中的U盘的序列号后，程序可以变成你自己的独立的Ｕ盘启动密匙，　只能你的Ｕ盘才能打开程序　不需要往Ｕ盘中存入任何文件，就可实现用Ｕ盘加密程序.只能通过你的U盘启动你的程序 程序中有详细的注释(Encrypt your program by a soul U-disk without saving anything in you disk Modify the program, U-disk serial number, the program can become your own independent U disk key, only you can open U disk U disk does not need to deposit any file, can be achieved U disk encryption program)

MD5加密算法，实现报文认证！！运算速度快，兼容性好(MD5 encryption algorithm, message authentication realize! ! Computing speed, better compatibility)
