CRC校验中叠加和校验方法的生成，校验等功能函数源码。

DES( Data Encryption Standard)算法，于1977年得到美国政府的正式许可，是一种用56位密钥来加密64位数据的方法。DES算法以被应用于许多需要安全加密的场合。-DES (Data Encryption Standard) algorithm, in 1977 the United States government"s official permission, is a key 56 to 64-bit data encryption methods. DES algorithm to be applied to many needs security encryption occasions.
