Cryptography History

Cryptography was used extensively during World War II, with a plethora of code and cipher systems fielded by the nations involved. In addition, the theoretical and practical aspects of cryptanalysis, or code-breaking, were much advanced.

Probably the most important code-breaking event of the war was the successful decryption by the Allies of the German "Enigma" Cipher. Poland achieved the first complete break into Enigma around 1932. They passed the techniques and insights used to the French and British Allies just before the outbreak of the war in 1939. British efforts at the Bletchley Park research station substantially improved them during the war.

Decryption of the Enigma Cipher allowed the Allies to read important parts of German radio traffic on important networks and was an invaluable source of military intelligence throughout the war. Intelligence from this source (and other high-level sources, including the Fish ciphers) was eventually called Ultra.

A similar break into the most secure Japanese diplomatic cipher, designated Purple by the US Army Signals Intelligence Service, started before the US entered the war. Product from this source was called Magic.

Message from Susan about Cryptogram Puzzles:

“I absolutely LOVE solving Cryptogram puzzles. Every night I solve a puzzle. Funny thing is: it relaxes me. You'd think solving puzzles would keep you awake, right?!”

In Cryptogram puzzles, the words have their letters substituted with other letters in a code that remains the same for that puzzle set. For example, every A might be a T, every E might be a W, and so on. The letter substitution is consistent in each individual puzzle.
