Actually, the real reason is not particularly sinister. The stansard rule, in 
both the US and UK is that everything crypro is so sensitive that it is only 
released after 50 years.

An exception to that was made in the case of the American solution of PURPLE in 
order to respond to persistent rumors that FDR deliberately suppressed advance 
knowledge of the attack on Pearl Harbor in order to get the US into the war.
