DCPcrypt Cryptographic Component Library

鉴于单纯设置一个计数器易被查出，通过修改使其不起作用。我们设计的程序可以通过数据文件，软件执行前通过关键字找到计数基数，然后计算和判别，如果在合理范围，则设定新的关键字，将计数基数放在新关键字指定的位置，并执行子程序 则启动自毁程序。

以前发的那个只实现了SHA-1, 现在补全了, sha-160, sha-224, sha-256, sha-384, sha-512-Previously issued only to realize that the SHA-1, is now a complete, sha-160, sha-224, sha-256, sha-384, sha-512
