key: {{ my\_key | hash('sha1') }} ...

Hashing filters

New in version 1.9.

To get the sha1 hash of a string:

{{ 'test1' | hash('sha1') }}

To get the md5 hash of a string:

{{ 'test1' | hash('md5') }}

Get a string checksum:

{{ 'test2' | checksum }}

Other hashes (platform dependent):

{{ 'test2' | hash('blowfish') }}

To get a sha512 password hash (random salt):

{{ 'passwordsaresecret' | password\_hash('sha512') }}

To get a sha256 password hash with a specific salt:

{{ 'secretpassword' | password\_hash('sha256', 'mysecretsalt') }}

An idempotent method to generate unique hashes per system is to use a  
salt that is consistent between runs:

{{ 'secretpassword' | password\_hash('sha512', 65534 |  
random(seed=inventory\_hostname) | string) }}
