问题描述

我需要访问joomla用户表 jos_users ,以便从外部php脚本[codeignitor]进行登录检查。

I need to access the joomla user table jos_users for login checking from external php script [codeignitor].

joomla存储这样的密码

joomla storing password like this

4e9e4bcc5752d6f939aedb42408fd3aa:0vURRbyY8Ea0tlvnTFn7xcKpjTFyn0YT

看起来这不是正常的MD5,所以我不能使用 md5(密码)

Looks like this is not the normal MD5 ,so i cannot use md5(password) .

可能的创建密码的方法是什么?

what is the possible way to create the password ?

谢谢。

推荐答案

Joomla密码是MD5哈希,但密码在哈希之前被盐化。
它们以 {hash}:{salt} 的形式存储在数据库中。此盐是一个长度为32个字符的随机字符串。

Joomla passwords are MD5 hashed, but the passwords are salted before being hashed. They are stored in the database as {hash}:{salt} this salt is a random string 32 characters in length.

所以要创建一个新的密码哈希你会做 md5($ password。$ salt)

So to create a new password hash you would do md5($password.$salt)

EDIT

好的,为了检查密码,请说用户 myguy 输入密码 mypassword ,您将从具有用户名 myguy 的数据库中检索该行。

Okay so for checking a password, say a user myguy enters the password mypassword, you would retrieve the row from the database that has username myguy.

在此行中,您将找到一个密码,说 4e9e4bcc5752d6f939aedb42408fd3aa:0vURRbyY8Ea0tlvnTFn7xcKpjTFyn0YT
你分割了密码哈希和盐:

In this row you'll find a password say 4e9e4bcc5752d6f939aedb42408fd3aa:0vURRbyY8Ea0tlvnTFn7xcKpjTFyn0YT. You split up the password hash and the salt:

$hashparts = preg_split (':' , $dbpassword);
echo $hashparts[0]; //this is the hash  4e9e4bcc5752d6f939aedb42408fd3aa
echo $hashparts[1]; //this is the salt  0vURRbyY8Ea0tlvnTFn7xcKpjTFyn0YT

现在使用此盐和密码计算哈希值 myguy 输入

now calculate the hash using this salt and the password myguy entered

$userhash = md5($userpassword.$hashparts[1]); // This would be 'mypassword' and the salt used in the original hash

现在如果这个 $ userhash $ hashparts [0] 与用户输入的密码相同。

Now if this $userhash and $hashparts[0] are identical the user has entered the correct password.
