Question 2.2: Microsoft Office 2007 onwards allows the use of the AES cryptographic algorithm with a 128-bit shared secret to protect access to documents. If AES keys can be tried with the same speed as RC4 keys using the computer described in Question 1.1, what is the maximum amount of time that it would take for a brute-force attack on a single document?
