如题 若不一样 该怎样用php翻写javascipt的md5加密方式

首先你的了解md5时干什么用的。你可以参考google活着我的这篇文章:http://segmentfault.com/blog/liangyi/1190000002409125

总的来说:md5是一种信息的摘要算法,它是和具体语言无关的。你可以用java、php或者javascript都可以实现,md5的值是根据信息是否发生改变而改变的。对于同一段信息,用上面的语言计算出来的值应该是一样的。不一样那说明他们对算法的实现不一样。

js哪来的md5,都是第三方实现的

话说回来,既然都叫做md5,算法肯定是一样的,无非是返回的数据值类型可能会存在差异

md5的计算结果是128bit散列值,某些Java库返回的就是16个字节的Byte数组(8bit=1Byte),而大部分标准md5实现都是直接返回这16个字节的Hex表示形式,即32个16进制数字拼起来的字符串。
