ansible passlib filter plugin

passlib_plugin.py

# this ansible/jinja2 filter plugin allows you to use passlib's *_crypt functions
# until ansible 2.0 comes out - see https://github.com/ansible/ansible/issues/11244.
#
# this filter depends on passlib being installed:
# $ pip install passlib
#
# put this into your playbook's `filter_plugins` folder.
#
# usage example:
# - name: create user
#   user:
#     name: username
#     password: "{{ user_password | passlib_hash('sha512', user_salt) }}"
