Finally, here it is, AES ported to Drupal 6. This is basically the same version as 1.2 for Drupal 5, but it also has a couple of small bugfixes and changes, which is why it's called 1.3.
Bugfixes:
* AES no longer alerts the user about a missing key if the user does not have the administer aes permission. This alert is now also logged in the watchdog.
* Fixed a bug which caused AES encrypted passwords to be created even when this feature was turned off if an existing account was given a new password.
