The substitution
cipher has one glaring problem to it; that frequency analysis of the symbols used
can be compared with the usage of the English letters to find out what a
message means. But this method is only effective when used on long messages. It
is kind of like reliability in science. If someone could send multiple short
messages, it would mean that it could be harder to break.

This message is intended for the addressee named and may contain privileged information
or confidential information or both. If you are not the intended recipient
please delete it and notify the sender.
