sha256的签名算法，纯C实现，已验证正确，在控制台上直接运行即可，(sha256 signature algorithm, pure C implementation ，has been verified properly and can be run directly on the console.)

加密算法3WAY代码文档,C++语言实现，编译通过(Encryption Algorithm)

检测CRC编码 看CRC编码在传输后是否有错误 有变动 (Detection CRC codes to see whether the CRC coding errors in the transmission there is a change)

用于车型定位识别所用的加密狗文件，非常实用(Dongle for vehicle location identification file used, very practical)

说明：  AES加密算法的加密部分，128位加密算法实现(AES encryption algorithm the encryption part, 128-bit encryption algorithms)

以DES加密算法为例理解对称密码算法，用计算机模拟DES加密解密算法。 (DES encryption algorithm as an example to understand the symmetric cipher algorithm, using computer simulation DES encryption and decryption algorithms.)

实现对单文件的DES加密解密，不限制大小，DES加密部分自写，非调用，用于学习DES原理。(The realization of the single document DES encryption and decryption, no limit to the size, DES encryption part self written, non call, for learning DES principle.)

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)

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

OpenSSL的RSA算法应用举例。是用VC写的，有实用价值。(RSA algorithm of OpenSSL is used and given an example. Written with VC, there is practical value. )
