+short_description: Manages server SSL profiles on a BIG-IP
+description:
+  - Manages server SSL profiles on a BIG-IP.
+version_added: 2.8
+options:
+  name:
+    description:
+      - Specifies the name of the profile.
+    required: True
+  parent:
+    description:
+      - The parent template of this monitor template. Once this value has
+        been set, it cannot be changed.
+    default: /Common/serverssl
+  ciphers:
+    description:
+      - Specifies the list of ciphers that the system supports. When creating a new
+        profile, the default cipher list is provided by the parent profile.
+  secure_renegotiation:
+    description:
+      - Specifies the method of secure renegotiations for SSL connections. When
+        creating a new profile, the setting is provided by the parent profile.
+      - When C(request) is set the system request secure renegotation of SSL
+        connections.
+      - C(require) is a default setting and when set the system permits initial SSL
+        handshakes from clients but terminates renegotiations from unpatched clients.
+      - The C(require-strict) setting the system requires strict renegotiation of SSL
+        connections. In this mode the system refuses connections to insecure servers,
+        and terminates existing SSL connections to insecure servers.
+    choices:
+      - require
+      - require-strict
+      - request
+  server_name:
+    description:
+      - Specifies the fully qualified DNS hostname of the server used in Server Name
+        Indication communications. When creating a new profile, the setting is provided
+        by the parent profile.
+  sni_default:
+    description:
+      - Indicates that the system uses this profile as the default SSL profile when there
+        is no match to the server name, or when the client provides no SNI extension support.
+      - When creating a new profile, the setting is provided by the parent profile.
+      - There can be only one SSL profile with this setting enabled.
+    type: bool
+  sni_require:
+    description:
+      - Requires that the network peers also provide SNI support. This setting only takes
+        effect when C(sni_default) is C(yes). When creating a new profile, the setting
+        is provided by the parent profile.
+    type: bool
+  server_certificate:
+    description:
+      - Specifies the way the system handles server certificates.
+      - When C(ignore), specifies that the system ignores certificates from server systems.
+      - When C(require), specifies that the system requires a server to present a valid
+        certificate.
+    choices:
+      - ignore
+      - require
+  certificate:
+    description:
+      - Specifies the name of the certificate that the system uses for server-side SSL
+        processing.
+  key:
+    description:
+      - Specifies the file name of the SSL key.
+  chain:
+    description:
+      - Specifies the certificates-key chain to associate with the SSL profile.
+  passphrase:
+    description:
+      - Specifies a passphrase used to encrypt the key.
+  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 profiles.
+    default: always
+    choices:
+      - always
+      - on_create
+  ocsp_profile:
+    description:
+      - Specifies the name of the OCSP profile for purpose of validating status
+        of server certificate.
+  partition:
+    description:
+      - Device partition to manage resources on.
+    default: Common
+  state:
+    description:
+      - When C(present), ensures that the profile exists.
+      - When C(absent), ensures the profile is removed.
+    default: present
+    choices:
+      - present
+      - absent
