%T "Codes, Ciphers and Secret Writing"

This brief pamphlet outlines some of the simple permutation and
substitution ciphers that have been used over time. The emphasis is
on the clever little tricks that go into making ciphers slightly
harder to crack. None of the algorithms are terribly sophisticated,
and exercises are given at the end of each chapter. Instructions are
given for decrypting some of the ciphers, even if you don't know the
key.

Two additional chapters address related topics. The first deals with
various forms of secret writing, such as invisible inks, or
steganographic messages. The last chapter briefly examines the
problem of creating messages that unknown people, with unknown
languages, may be able to solve (such as sending messages to the
stars).

None of the material is strenuous, but this may be a nice start before
moving on to a work such as Gaines "Cryptanalysis" (cf. BKCRPTAN.RVW).
