Check WordPress hashed password with plain password

Question

I am building a external application for which user login credentials will be taken from WordPress site database table 'users'

WordPress uses PHPass hashing , I am unable to validate username and password for my external application as the password in database table 'users' is hashed

I am trying to check plain password with hashed password using wp_check_password function but I am failing, nothing is written back with this code

<?php

$password = '965521425';
$hash = '$P$9jWFhEPMfI.KPByiNO9IyUzSTG7EZK0';

require_once('/home/nhtsoft/public_html/project/wp-includes/class-phpass.php');

function wp_check_password($password, $hash) {
    global $wp_hasher;

    if ( empty($wp_hasher) ) {
        $wp_hasher = new PasswordHash(8, true);
    }
    $check = $wp_hasher->CheckPassword($password, $hash);
    return apply_filters('check_password', $check, $password, $hash);
}    
?>

this code is giving me an empty page.

How to check this password so that I can use these WordPress credentials for external app login?

Solution 1

you have passed wrong hash value , hash value for 965521425 is $P$BmI5G.LOoEx1iH.naNqVhWnSh5sMp31 and you just need to write below code into your file:

require_once($_SERVER['DOCUMENT_ROOT']."/wp-load.php");
 $password = '965521425';
 $hash = '$P$BmI5G.LOoEx1iH.naNqVhWnSh5sMp31';
 var_dump(wp_check_password($password, $hash));

exit;

Solution 2

In your code, you include the wp library and it looks like you redefine a function named wp_check_password but you do not call any function at all. Add the following line before the closing php tag ("?>") and try again.

echo (wp_check_password($password, $hash) ? 'TRUE' : 'FALSE');

Keep an eye on the error logs in case you miss some dependencies.

Solution 3

i would simply do this <?php wp_check_password( $password, $hash, $user_id ) ?> Refer

wordpress will not use only md5 hashing. . . . @user2092317

yeah,i got output , you can place code into functions.php and var_dump(wp_check_password($password, $hash); exit; and check it.

as i need this to be implemented in external application not releated to wordpress, i have included class-phpass.php file and wrote the above code. . . sorry but i didnt get you, where to place the code. . .can u please tell me in detail. . .

[Bhumi Shah]

if you are using external file, you need to load wp-load.php file. see code i have edited above.
