分享求加密算法，求解密
原密码：admin
加密后：A79ECB371DC0F477A39B0EB0C01029D53DD6E361
有大神能知道加密算法么？

此加密过程是单向的，无法逆向解密；

四十位的密文 
，我认为无解

这个谁知道啊，你要看代码才知道，
而且很多自己写的加密，都有一个加密密钥的。

结贴，已经破解成功了，是先sha加密，然后再Hash，关键是加密源是用户名id+用户密码，所以各位，存在误导；已经ok了

base64是个好东西。sha1也很不错。
楼主你的这个问题可以考死人。。。

很接近了，并且非单纯sha1算法，估计加有hash，而且对应对应16进制字符为{ '0', '1', '2', '3', '4', '5', '6', '7', '8', '9', 'A', 'B', 'C', 'D', 'E', 'F' };结果已经非常接近，但是任然不对，现在估计就是密钥的问题了

还有base64 我也试过了，像2楼所说，至少不是普通的加密方式
