C(selfsigned), C(ownca), C(acme), C(assertonly), C(entrust)) for your certificate. - The C(assertonly) provider is intended for use cases where one is only interested in checking properties of a supplied certificate. Please note that this provider has been deprecated in Ansible 2.9 and will be removed in Ansible 2.13. See the examples on how to emulate C(assertonly) usage with M(openssl_certificate_info), M(openssl_csr_info), M(openssl_privatekey_info) and M(assert). This also allows more flexible checks than the ones offered by the C(assertonly) provider. - The C(ownca) provider is intended for generating OpenSSL certificate signed with your own CA (Certificate Authority) certificate (self-signed certificate). - Many properties that can be specified in this module are for validation of an existing or newly generated certificate. The proper place to specify them, if you want to receive a certificate with these properties is a CSR (Certificate Signing Request). - "Please note that the module regenerates existing certificate 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 certificate, consider using the I(backup) option." - It uses the pyOpenSSL or cryptography python library to interact with OpenSSL. - If both the cryptography and PyOpenSSL libraries are available (and meet the minimum version requirements) cryptography will be preferred as a backend over PyOpenSSL (unless the backend is forced with C(select_crypto_backend)). Please note that the PyOpenSSL backend was deprecated in Ansible 2.9 and will be removed in Ansible 2.13. requirements: - PyOpenSSL >= 0.15 or cryptography >= 1.6 (if using C(selfsigned) or C(assertonly) provider) - acme-tiny >= 4.0.0 (if using the C(acme) provider) author: - Yanis Guenane (@Spredzy) - Markus Teufelberger (@MarkusTeufelberger) options: state: description: - Whether the certificate should exist or not, taking action if the state is different from what is stated. type: str default: present choices: [ absent, present ] path: description: - Remote absolute path where the generated certificate file should be created or is already located. type: path required: true provider: description: - Name of the provider to use to generate/retrieve the OpenSSL certificate. - The C(assertonly) provider will not generate files and fail if the certificate file is missing. - The C(assertonly) provider has been deprecated in Ansible 2.9 and will be removed in Ansible 2.13.
