Ah, ok, that makes sense.

That might be an option, right.

Great! The FormFu-filter-way did its job:

<catalyst root>/root/forms/foobar.yml:

(...)
elements:
  - type: Password
    name: mypass
    label: Enter password
    filters:
      - type: Callback
        callback: <catalyst root>::Controller::somewhere::myhashedpassword
    constraints:
      - type: Equal
        others: mypass_confirm
      - type: Required
(...)

<catalyst root>/lib/MyApp/Controller/somehere.pm:

(...)
sub myhashedpassword {
  my ($value) = @_;
  return sha1_hex($value);
}
(...)

Thanks a lot! :-D
