You would hash the password the user tried using at the UCP:

PHP код:

$hashed_password = hash("whirlpool", $_POST["password"]); 


And, after hashing the password they tried using, you would compare it to the value you have in your SQL database.

PHP код:

if($hashed_password == $sql_result["password"])
{
    // They're a match.
}
