Ansible Module: Password Lookup

This is a patch for the original Ansible password lookup, to make sure password files encrypted with ansible-vault are decrypted properly.

It uses Ansible's internal method _get_file_contents, just like the file lookup plugin:

content = None
if os.path.exists(b_path):
  content = to_text(self._loader._get_file_contents(b_path)[0], errors='surrogate_or_strict')

Why the patch?

The current implementation of the password lookup has an annoying bug.

Encrypt a file with ansible-vault:

• Ansible's copy module decrypts the file, writes the decrypted content to the target host.
• The file lookup module decrypts the file, returns the decrypted content.
• The password lookup module … well, it returns the encrypted content of the file.

This causes all kinds of trouble when you use the password plugin to create randomized, low-impact passwords (e.g. for technical .htaccess users, cookie secrets, etc.) which are stored encrypted inside the repository.

Usage

Copy the lookup_plugins directory to the root of your Ansible project and execute patch.sh inside of it. This will download the latest version of the original password.py lookup plugin and apply the patch.
