Andy,
I'm not sure there is a method to determine it data has been encrypted and
not compressed. In either case the data will be converted to a different
data stream. If you took a Sniffer Trace for the same message on either side
of the encryption unit and compare the message length, the size may indicate
if compression is being used. Setting the filters may be the biggest
difficulty.

Does anyone know if a method or tool that will verify encryption on a data
stream? I am trying to verify that data is encrypted and not compressed.

Please let me know if you do.

Thanks,
Andy
