#1 In the short to medium term thinking your codes have been compromised when they haven't is probably more disruptive than having them compromised and not knowing. The timing incates to me it's the former.

#2 If you would like the least glimpse into this sort of cryptological lunacy, please find a copy of "The Puzzle Palace," by James Bamford. His book deals with the NSA (National Security Agency), whose Eisenhower era charter remains classified to this day.

Cryptography has advanced from the World War model of a pencil and pad of paper. Alan Turing made sure of that when he helped crack Enigma. Those of you who have read "The Puzzle Palace" might wish to peruse another article:

The above model -- that the cryptographer may design and analyse a cipher so well that no cryptanalyst will be able to exploit any weakness ever -- is not the only approach to the encryption problem. In this report we describe a cipher that is based upon a different meta-model. Using HCIA neither the cryptanalyst nor the cryptographer will be able to perform detailed analysis of the cipher system. This is due to that a generator model is used where an instance of a cipher system is produced at runtime, kept secret during encryption, and then discarded immediately afterwards.

Nice work if you can get it.
