*** 89,98 ****
--- 89,119 ----
             In other words, the enabled behavior is that any message that CAN
             be encrypted SHOULD be encrypted, while the required behavior is
             that any message that CAN be encrypted MUST be encrypted.
  
  
+        encrypt_cipher
+ 
+            Specifies SMB 3.1.1 Encryption Cipher. This property is only used
+            when encryption is On (see encrypt property) and negotiated SMB
+            dialect is 3.1.1 or higher (see max_protocol property). Otherwise
+            it is ignored.  If the property is not set the default encryption
+            algorith is AES-128-GCM.
+ 
+            The property can be set to one of these values:
+ 
+            aes128-ccm
+                         AES-128-CCM. This is the only cipher used for SMB
+                         3.0.2 dialect. It is deprecated by AES-128-GCM cipher.
+ 
+ 
+            aes128-gcm
+                         AES-128-GCM. This is default cipher for SMB 3.1.1
+                         dialect.
