short_description: Generate OpenSSL Certificate Signing Request (CSR)
description:
    - This module allows one to (re)generate OpenSSL certificate signing requests.
    - It uses the pyOpenSSL python library to interact with openssl. This module supports
      the subjectAltName, keyUsage, extendedKeyUsage, basicConstraints and OCSP Must Staple
      extensions.
    - "Please note that the module regenerates existing CSR if it doesn't match the module's
      options, or if it seems to be corrupt. If you are concerned that this could overwrite
      your existing CSR, consider using the I(backup) option."
