CRC 算法源代码 工程测试确定可用，VC环境编译操作 本人用于COS系统。-CRC algorithm source code available test works, VC environment compiler I used COS operating system.

加密算法，先将表示时间的字符串进行加密，同时通过CRC进行校验。 （同时例子中也涉及到ini配置的读取、注册表的操作等）-Encryption algorithm, the first time a string that is encrypted by the CRC check at the same time. (And also the example related to the reading ini configuration, registry operations, etc

实现3EDS加密解密，计算CRC，计算MD，可以对独立内存进行操作，有test工程。-3EDS achieve encryption and decryption, computing CRC, calculated MD, memory can operate independently, there are test projects.
