Suppose that Malice is attempting to guess the password for a smartphone taken from Alice. Through research, Malice knows that the password is a total of 8 characters including English letters upper and lower case, and digits 0-9. Malice was able to obtain the first 4 characters in the password by posing as a maintenance repair worker at Alice’s workplace to observe her (using social engineering), but does not have the remaining characters. (a) Determine the password search space of this password Malice is attempting to obtain (b) Repeat the calculation, assuming that Alice does not use numbers/digits in her passwords
