HomeBackend DevelopmentPHP Tutorial两次MD5加密在怎么解密,求高人

cf8497dc0aa9f7118061666012bfe3eb  这个MD5是两次MD5加密产生的,现在能不能反解。


回复讨论(解决方案)

很遗憾的告诉你不能

md5加密是单向的,不能解密

貌似是解密不过来的

md5是不可逆的,网上所谓的“解密”都是把“加密”结果存储到数据库再比对的

md5不能解密的兄弟

解密了干什么,想钓鱼吗?

你可以写个程序自己碰碰 祝你好运

只能暴力破解,不能反向解密的。

暴力破解
1、有一个字典。
2、从字典中读取一条记录
3、if(strtolower(md5(md5($字典记录))) == 'cf8497dc0aa9f7118061666012bfe3eb'){
            echo '成功'.$字典记录;
            exit;
}

搜索“彩虹表”,下载彩虹表,然后暴力破解,参考楼上方法。

不能解密!!!!!!!!!!

MD5貌似不能解的吧

甭??次了,就算是一次就?你受的

不能揭密!!!

我原本想着进来看看有什么好办法呢。现在看来,楼主给分吧。

MD5 是单向加密滴。

理论上是可以的!
由于你是对 MD5 的结果做 MD5
而 MD5 的结果是 32 个十六进制符号组成的串,是可以穷尽的
所以枚举一下就可得到 1  次 MD5 的结果
网上有很多 MD5 破解服务,你只要输入 1  次 MD5 的结果,就可得到原始串
