Suppose passwords were computer-supplied pseudorandom number generated nine-character long and were taken from the character set consisting of uppercase letters and digits so that the adversary has to search through all character strings of length 9 from a 36-character alphabet. Would a pseudorandom number generator with 2¹⁶ possible starting values suffice? If yes, how? If not, then what should be the appropriate range for this pseudorandom number generator?
