What type of hash does WordPress use?
Here is an example of a WordPress hash:
$P$Bp.ZDNMM98mGNxCtHSkc1DqdRPXeoR.
The WordPress password hasher implements the Portable PHP password hashing framework, which is used in Content Management Systems like WordPress and Drupal.
They used to use MD5 in the older versions, but sadly for me, no more. You can generate hashes using this encryption scheme at http://scriptserver.mainframe8.com/wordpress_password_hasher.php.
