(I realised subsequently that it reads past the end of the buffer if
system memory is low and the input buffer was less than
PLANB_BUF_SIZE; oops).

A common characteristic of encrypted data is that it has a low degree
of redundancy; the method for which I provided code performs a
rudimentary test for redundancy in the data simply by attempting to
compress it. If you want a better method of attacking the problem,
and to be sure there are more sophisticated techniques, you will need
to learn about information theory.
