Please don&#x27;t put words into my mouth.<p>The original top level comment was poor and my comment was responding to it, e.g. Armstrong says &quot;AES assumes the data to be encrypted is a multiple of 16 bytes long&quot;, which is correct so I don&#x27;t know why the OP felt the need to say &quot;for the record, the AES algorithm itself does not encrypt arbitrarily sized data&quot; as Armstrong did not claim as such.
