这是一个用Java编写的MD5算法的快速实现，经试验可用于Android上，也可以用于其他Java平台。 有关详细信息，请参见该项目网站： http://www.twmacinta.com/myjava/fast_md5.php-This is a fast implementation of the MD5 algorithm written in Java. For details, see the project website at: http://www.twmacinta

Some operating systems support more than one type of hash. In fact, sometimes the standard DES-based algorithm is replaced by an MD5-based algorithm. The hash type is triggered by the salt argument. Prior to 5.3, PHP would determine the available alg
