When moved to the collection C(community.crypto), it was renamed to M(community.crypto.x509_certificate_info). From Ansible 2.10 on, it can still be used by the old short name (or by C(ansible.builtin.openssl_certificate_info)), which redirects to M(community.crypto.x509_certificate_info). When using FQCNs or when using the L(collections,https://docs.ansible.com/ansible/latest/user_guide/collections_using.html#using-collections-in-a-playbook) keyword, the new name M(community.crypto.x509_certificate_info) should be used to avoid a deprecation warning. requirements: - cryptography >= 1.6 author: - Felix Fontein (@felixfontein) - Yanis Guenane (@Spredzy) - Markus Teufelberger (@MarkusTeufelberger) extends_documentation_fragment: - community.crypto.attributes - community.crypto.attributes.info_module - community.crypto.name_encoding options: path: description: - Remote absolute path where the certificate file is loaded from. - Either O(path) or O(content) must be specified, but not both. - PEM and DER formats are supported. type: path content: description: - Content of the X.509 certificate in PEM format. - Either O(path) or O(content) must be specified, but not both. type: str version_added: '1.0.0' valid_at: description: - A dict of names mapping to time specifications. Every time specified here will be checked whether the certificate is valid at this point. See the RV(valid_at) return value for information on the result. - Time can be specified either as relative time or as absolute timestamp. - Time will always be interpreted as UTC. - Valid format is C([+-]timespec | ASN.1 TIME) where timespec can be an integer + C([w | d | h | m | s]) (for example V(+32w1d2h)), and ASN.1 TIME (in other words, pattern C(YYYYMMDDHHMMSSZ)).
