How to convert text to phpbb hash?

Question

I am trying to convert a test password (testing4) into a phpbb3 hash. This is the code I have tried:

<?php
/** 
*
* @package phpBB3
* @version $Id: v3_dbal.xml 44 2007-07-25 11:06:55Z smithy_dll $
* @copyright (c) 2005 phpBB Group 
* @license http://opensource.org/licenses/gpl-license.php GNU Public License 
*
*/

/**
* @ignore
*/
define('IN_PHPBB', true);
include ("functions_phpbb.php");

$data['new_password'] = "testing4";

$user_row = array(
    'user_password' => phpbb_hash($data['new_password'])
    );

$hash = $user_row['user_password'];

echo $hash;
?>

and this doesn't work either:

$pass = "testing4";
$hash = phpbb_hash($pass);

Both times I recieve the following error message:

Fatal error: Call to a member function sql_escape() on a non-object in /home/a8544020/public_html/Pass/functions_phpbb.php on line 149

I have tried it on 2 different hosts without any luck. Otherwise is there an online service that simply converts text to the hash?

Thanks in advance

Answer 1

I'm assuming your functions_phpbb.php file is a copy of the includes/functions.php file of the phpBB3 package.

Now, the reason you are getting this error is because the phpbb_hash function uses the phpBB unique_id function for entropy, which depends on a database connection (to change and persist the entropy on every request).

There's two ways to fix this.

a) include phpBB's common.php , which will bootstrap your code for phpBB (including db connection, error handlers, etc).

b) phpBB3 uses phpass for hashing. I suggest you simply download the standalone phpass package and use that to generate the hash.

Little caveat: phpBB3 changes the hash identifier from '$P$' to '$H$' (don't ask me why), so you will have to change this line:

$output = '$P$';

to:

$output = '$H$';

Since option a) adds quite some overhead, and you are probably only wanting to use the hashing functions, I'd suggest option b).

Answer 2

Maybe the other way. I have used the library from: http://www.openwall.com/phpass/ To make it working, you must change first 3 characters of generated HASH:

$P$

to

$H$

used in phpbb

我想知道为什么他们通过SQL转义函数运行密码哈希..但你可以简单地尝试将该函数定义为虚拟：

function sql_escape($str) { return $str; }
