What HASH does OXWALL uses to encrypt its passwords in its database when a user creates an account?

Question

I have tried it but doesnt reflect properly. Someone please help me...

This is my salt value from config.php

define('OW_PASSWORD_SALT', 'xEHNxiEXdz7GK');

When i enter the password as 31121993Aa from signing up it generates

82416b9973e6fc2279f8e2c54eae6c0d555eae5ad1760985ce1a65b1139c0320 

But when I create a custom sign up page which inserts data into this table and I use the same password i.e 31121993Aa and I get

db57e80826fd86d6b00aebf21b34d1c382e123d17a02a1d008ced708af81441e

when i use this code in my php

$username=$_POST['username'];
$password=$_POST['password'];
$salt = 'xEHNxiEXdz7GK';
$pass = "password";
$hashit = hash('sha256',$salt.$pass);
$password1=$_POST['password1'];
mysql_query("INSERT INTO oxwa_base_user(username,password,password1,email)VALUES('$username','$hashit','$password1','$mail')");

Please help me....
