bit keyseach machine in article apr lokkur dexter mi us scs lokkur dexter mi us steve simmons writes normally i d be the last to argue with steve but shouldn t that read years for all solutions i mean if we can imagine the machine that does trial nanosecond we can imagine the storage medium that could index and archive it hmmmm i think with really large keyspaces like this you need to alter the strategy discussed for des attempt decryption of several blocks and check the disctribution of the contents i don t think it s at all feasible to keep encryptions of a known plaintext block on any amount of tape or cd rom and certainly not such encrypted blocks anyone know a cheap way of converting every atom in the solar system into a one bit storage device actually a keysearch of this kind shouldn t be much worse than the simpler kind in terms of speed it s just that you have to do it over for every encrypted message dumb question has anyone ever done any serious research on how many legitimate ascii encoded byte blocks there are that could be part of an english sentence for attacking des in ecb mode it seems like a dictionary of this kind might be pretty valuable john kelsey
