用于蜂窝宽带的流和文件的RC5加密程序.包含数字签名,消息加扰等功能.-RC5 is a block cipher that was originally designed by Ronald Rivest (http://theory.lcs.mit.edu/~cis/pubs/rivest/rc5.ps). We have implemented and optimized the RC5 encryption/decryption library for the Sony-Toshiba-

根据A5原理，程序生成了大小250KB左右的A5密钥流文件。用户可自行设定三个LFSR的结构，以及三个LFSR的初始值。-According to the principle of A5, the program generate an A5 key stream file，whose size is about 250KB . Users can set the structure of three LFSR, and three LFSR s initial value.
