Allowing (or requiring) users to use numerical digits (including 0) and one of 28 “special characters” dramatically increases the number of possible passwords. Furthermore, passwords often are case-sensitive, effectively doubling the size of the alphabet by defining 52 distinct letter characters. Assuming that passwords are case-sensitive and can include numerical digits and special characters, how many possible 7, 8 and 10 character passwords can be created?
