notes:
  - "If a new enough version of the C(cryptography) library
     is available (see Requirements for details), it will be used
     instead of the C(openssl) binary. This can be explicitly disabled
     or enabled with the C(select_crypto_backend) option. Note that using
     the C(openssl) binary will be slower and less secure, as private key
     contents always have to be stored on disk (see
     C(account_key_content))."
  - "Although the defaults are chosen so that the module can be used with
     the L(Let's Encrypt,https://letsencrypt.org/) CA, the module can in
     principle be used with any CA providing an ACME endpoint, such as
     L(Buypass Go SSL,https://www.buypass.com/ssl/products/acme)."
requirements:
  - python >= 2.6
  - either openssl or L(cryptography,https://cryptography.io/) >= 1.5

      - "I(Warning): the content will be written into a temporary file, which will
         be deleted by Ansible when the module completes. Since this is an
         important private key — it can be used to change the account key,
         or to revoke your certificates without knowing their private keys
         —, this might not be acceptable."
      - "In case C(cryptography) is used, the content is not written into a
         temporary file. It can still happen that it is written to disk by
