Assume: A password is 8 characters in length, and there 15 different characters from which we can select. - The password file includes 64 passwords, an attacker has a dictionary of 128000 common passwords, and the probability of having a password from password file in the dictionary is 0.2. Work is defined as number of computed hashes. - Work time = 3xWork seconds. Example: Work = 10 hashes, then Work time =3x10 = 30 seconds. What is the expected number of hours needed to find the password for a specific user if salts are used and dictionary is used? 1067871.094 854307.542 1067876.427 Answer not given 1067897.760
