[ale] Security is still hard

YUP!  A client asked me to "sniff" traffic that another supplier claimed
was encrypted and I proved that it was not!

In another case a very large manufacturer (you'd instantly recognize their
name) hired a satellite company to provide encrypted communications to
its dealers around the word.  One very smart dealer used a line analyzer
to prove that the communications was NOT encrypted and that each dealer
could see every other dealer's supposedly confidential sales information.

This would allow another dealer to snatch an impending sale away!  The
manufacturer hired a well-known computer security company to fix it and
they contracted with me to write the communication code to encrypted it.

Also, when analyzing don't be fooled by simple obscuring that anyone
can crack quickly, such as ROT 13 (Caeser encoding) that replaces each
'a' with 'n', 'b' with 'o', etc.
