I am writing an historical piece on crypt(3) optimisation and password guessing heuristics. This naturally enough envolves tracking down and analysing various code/papers that have been seen as significant and/or infulential in those areas. In the late 80's Matt Bishop while at NASA, wrote DESZIP, which for a while was the seminal work. Matt has pointed me to a US summer 1987 article which describes some of the DES optimisations, however as I am an Australian national, Matt can not legally send me the actual implimentation to me due to idiotic ITAR restrictions. If someone not as constrained could address the problem described, I should be delighted. -- "Of all tyrannies a tyranny sincerely exercised for the good of its victims may be the most oppressive. It may be better to live under robber barons than under omnipotent moral busybodies, The robber baron's cruelty may sometimes sleep, his cupidity may at some point be satiated; but those who torment us for own good will torment us without end, for they do so with the approval of their own conscience." - C.S.
