Long length salt problem

[maintenance]

Hi,

I'm trying to find a way to revert a password, I know the salt code and format:

SALT = GVph--------  57 lenght salt   -----------------erBB7Q0a

I know the PHP is storing passwords on the database using the same salt always, in this format:

<?php   $pass = md5($salt . $input_password); ?>

$input_password is at least 5 alphanumeric.

so, the total length will start from 62.

the password should not be more then 8 chars length, but I can't run HashCat due to this limitation.

I've just made a test with a password I know, and hashcat was not able to find it.
