Many thanks for the link to Hitt's book -- always valuable. What was new to me was the www.archive.org site with its on-line documents. I searched for "cryptanalysis", "cryptography", etc. and found two classical items of interest: Andre Langie's "Cryptography" (translated by J.W. Macbeth) link: Andre Langie's "Cryptography" W. W. Rouse Ball, "Mathematical recreations" (which contains a chapter on cryptography) link: Mathematical Recreations FYI, look at the end of Langie/Macbeth for a test message created by J.C.H. Macbeth. Is anyone willing to try to solve it? The solution is to be found in a Cryptologia article: THE MACBETH TEST MESSAGE David Shulman Cryptologia, Volume 3, Issue 2, 1979, Pages 100 – 104 If anyone is interested in tackling it with some judicious hints, just post your requests in this forum. The system should be revealed (a-la Kerckhoff) with the challenge being to solve the given test message. I believe hill-climbing could come in handy here. Moshe
