md5的全称是message-digest algorithm 5(信息-摘要算法),经md2、md3和md4发展而来。它的作用是让大容量信息在用数字签名软件签署私人密匙前被"压缩"成一种保密的格式(就是把一个任意长度的字节串变换成一定长的大整数)。不管是md2、md4还是md5,它们都需要获得一个随机长度的信息并产生一个128位的信息摘要。虽然这些算法的结构或多或少有些相似,但md2的设计与md4和md5完全不同,那是因为md2是为8位机器做过设计优化的,而md4和md5却是面向32位的电脑。md5的典型应用是对一段信息(message)产生信息摘要(message-digest),以防止被篡改。
