    password: *password*
    store_location: LocalMachine
    key_storage: machine
    state: present

- name: HTTPS binding
  community.windows.win_iis_webbinding:
    name: "{{ win_web }}"
    port: 443
    ip: "*"
    protocol: https
    certificate_hash: "thumbprint"
    host_header: "{{ win_web_dns }}"
    ssl_flags: 1
    state: present

EXPECTED RESULTS
