Migrated password hashes support

I’ve done some testing and can confirm that it doesn’t work with Drupal 7, which apparantly uses SHA-512 according to Drupal 7: Secure password storage by default at last | Jon Cave

I’ll create a PR if I’m able to add a compatible one.

Hi there, by any chance has anything changed regarding Drupal 7 support?
