 = Password encryption limitations
 
 Open Liberty supports the Advanced Encryption Standard (AES) encryption for passwords that are stored in the `server.xml` file.
-When you use this option for protecting passwords in the Open Liberty configuration, understand the limitations to the protection that AES encryption provides. Currently, Open Liberty supports AES-128 encryption.
+When you use this option for protecting passwords in the Open Liberty configuration, understand the limitations to the protection that AES encryption provides.
+
+The Open Liberty `securityUtility encode` command uses AES-256 encryption when the `--encoding` option is set to `aes`. The default value for this option is `xor`. For AES decryption, Open Liberty supports both AES-128 and AES-256.
 
 Encrypting a password in the Open Liberty configuration does not guarantee that the password is secure or protected.
 Encrypting a password means that someone who can see the encrypted password cannot easily recover the password unless they know the encryption key.
