RC5加密算法类C#

RC5分组密码算法是1994由麻萨诸塞技术研究所的Ronald L. Rivest教授发明的，并由RSA实验室分析。它是参数可变的分组密码算法，三个可变的参数是：分组大小、密钥大小和加密轮数。在此算法中使用了三种运算：异或、加和循环。-RC5 encryption algorithm class C#

RC5 block cipher algorithm in 1994 by Professor Ronald L. Rivest Massachusetts Institute of Technology invention, RSA by laboratory analysis. It is a variable parameter block cipher algorithm, three variable parameters are: packet size, key size and encryption rounds. Use the three operations in this algorithm: XOR, add and circulation.
