Four your ATM debit card, you have a 4-decimal-digit personal secret code. In the absence of any clue, a brute-force attack takes time-‘t’ to crack the code on an ATM terminal. Therefore ‘t’ is the secure-time for a customer to report in case the card is misplaced. Your Bank has decided to facilitate an increased secure-time. Out of the following, which option should provide the largest rise in the value of ‘t’ ?

Instead of 4-decimal-digits, maintain the personal secret code in 4-hexadecimal-digits.
|
|
|
Instead of 4-decimal digits, maintain a 5-decimal-digit personal secret code.
|
