leiw on "How to authentication with Drupal 7.23"

Hello,

I have Drupal 7.23 site that want to migrate to Wordpress 3.7, Google told me Drupal 7.23 user password can't migrate to Wordpress 3.7, because encryption problem.

Any API/Bridge that can let Wordpress 3.7 user login from Drupal 7.23 user login and password ?

Thanks
