# 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

L1 cache reference ......................... 0.5 ns
Branch mispredict ............................ 5 ns
L2 cache reference ........................... 7 ns
Mutex lock/unlock ........................... 25 ns
Main memory reference ...................... 100 ns             
Compress 1K bytes with Zippy ............. 3,000 ns  =   3 µs
Send 2K bytes over 1 Gbps network ....... 20,000 ns  =  20 µs
