des数据加密算法原理与实现。

组播密钥的批次更新算法，基于LKH的单次密钥更新方案和Batch Rekeying方案的原理、结构和密钥更新过程等。并着重对 Batch Rekeying 方案的性能与单次密钥更新方案作了简单的比较。 通过比较和分析得到结论:定时更新的Batch Rekeying 方案在更新开销上比单次更新更有优势 -Multicast key batch update algorithm, Based on the LKH single Rekeying program and the program Batch Rekeying principle, Rekeying structure and processes. And Batch Rekeying focused on the performance of the program with a single Rekeying program with a simple comparison. By comparing and analyzing conclusions : regularly updated Batch Rekeying program in the updated overhead than a single update more advantages

为一个字节或字符数组或串计算md5值，内部只创建一个数组，节省分配时间，节省内存 完全是static方法，线程安全 注意对返回值的处理，见注释-for a byte array or character string or md5 value calculation, only to create an internal array, saving time allocated to save memory is completely static method, thread-safe attention to the return value, see note
