Q: "Encode a given string."

A: Use hash filter. For example, the command and the filter

    - shell: echo -n "mypassword" | sha1sum
      register: result
    - debug:
        var: result.stdout
    - set_fact:
        pswd: "{{ 'mypassword' | hash('sha1') }}"
    - debug:
        var: pswd

give the same results

    "result.stdout": "91dfd9ddb4198affc5c194cd8ce6d338fde470e2  -"

    "pswd": "91dfd9ddb4198affc5c194cd8ce6d338fde470e2"
