[Cryptography] traffic analysis -> let's write an RFC?, and sunlight

[Robert L Wilson]

I was told years ago that the cryptography group within NSA had as a 
standard that no crypto system could be considered secure unless I could 
give you all the details as to how it works and you still could not 
break it. There are probably people in this forum who could comment on 
that as history, but regardless of whether it is historically accurate 
it has always seemed to be a goal to strive for.
