Hi James. your hint was actually very inspiring.
After concatenating 'drupal$' to the imported password, I was still unable
to authenticate. Then I realized that the passwords are in unicode but the
hasher considers them to be ascii, so I added :
password = password.encode('ascii','ignore')
at the begining of the both 'encode' and 'verify' methods
This solved the problem and saved my escape rout out of drupal :)
Thank you very much for your hint.
