+description:
+  - Manage OCSP configurations on BIG-IP.
+version_added: 2.8
+options:
+  name:
+    description:
+      - Specifies the name of the OCSP certificate validator.
+    required: True
+  cache_error_timeout:
+    description:
+      - Specifies the lifetime of an error response in the cache, in seconds.
+  proxy_server_pool:
+    description:
+      - Specifies the proxy server pool the BIG-IP system uses to fetch the OCSP
+        response.
+      - This involves creating a pool with proxy-servers.
+      - Use this option when either the OCSP responder cannot be reached on any of
+        BIG-IP system's interfaces or one or more servers can proxy an HTTP request
+        to an external server and fetch the response.
+  cache_timeout:
+    description:
+      - Specifies the lifetime of the OCSP response in the cache, in seconds.
+  clock_skew:
+    description:
+      - Specifies the tolerable absolute difference in the clocks of the responder
+        and the BIG-IP system, in seconds.
+  connections_limit:
+    description:
+      - Specifies the maximum number of connections per second allowed for the
+        OCSP certificate validator.
+  dns_resolver:
+    description:
+      - Specifies the internal DNS resolver the BIG-IP system uses to fetch the
+        OCSP response.
+      - This involves specifying one or more DNS servers in the DNS resolver
+        configuration.
+      - Use this option when either there is a DNS server that can do the
+        name-resolution of the OCSP responders or the OCSP responder can be
+        reached on one of BIG-IP system's interfaces.
+  route_domain:
+    description:
+      - Specifies the route domain for fetching an OCSP response using HTTP
+        forward proxy.
+  hash_algorithm:
+    description:
+      - Specifies a hash algorithm used to sign an OCSP request.
+    choices:
+      - sha256
+      - sha1
+  certificate:
+    description:
+      - Specifies a certificate used to sign an OCSP request.
+  key:
+    description:
+      - Specifies a key used to sign an OCSP request.
+  passphrase:
+    description:
+      - Specifies a passphrase used to sign an OCSP request.
+  status_age:
+    description:
+      - Specifies the maximum allowed lag time that the BIG-IP system accepts for
+        the 'thisUpdate' time in the OCSP response.
+  strict_responder_checking:
+    description:
+      - Specifies whether the responder's certificate is checked for an OCSP
+        signing extension.
+    type: bool
+  connection_timeout:
+    description:
+      - Specifies the time interval that the BIG-IP system waits for before
+        ending the connection to the OCSP responder, in seconds.
+  trusted_responders:
+    description:
+      - Specifies the certificates used for validating the OCSP response
+        when the responder's certificate has been omitted from the response.
+  responder_url:
+    description:
+      - Specifies the absolute URL that overrides the OCSP responder URL
+        obtained from the certificate's AIA extensions. This should be an
+        HTTP-based URL.
+  update_password:
+    description:
+      - C(always) will allow to update passwords if the user chooses to do so.
+        C(on_create) will only set the password for newly created OCSP validators.
+    default: always
+    choices:
+      - always
+      - on_create
+  partition:
+    description:
+      - Device partition to manage resources on.
+    default: Common
+    version_added: 2.5
+  state:
+    description:
+      - When C(present), ensures that the resource exists.
+      - When C(absent), ensures that the resource does not exist.
+    default: present
+    choices:
+      - present
+      - absent
+extends_documentation_fragment: f5
+notes:
+  - Requires BIG-IP >= 13.x.
