# A2 Part I **Deadline:** Monday, 03/12/18, 11:59 pm *This assignment may be done as individuals or with one partner. If you choose to work with a partner, you should form a group on CMS and submit one solution.* **Warning:** This homework has two parts. You are currently looking at Part I. You need to decrypt Part II. Part II is much longer than Part I, so you should start early. Part I Decrypt <a href="a2-part2.enc">Part II</a> of this homework (available on CMS). It is encrypted with AES-128 in CBC mode and Base64 encoded. The randomly-generated IV is 0xa65d853342a0cf867e0449890b2c9b94. The key is the current year repeated eight times, treated as a hexadecimal number—that is, 0x20182018201820182018201820182018. Hint: You could use any cryptographic library of your choice to implement the decryption. But you might find the command-line tool openssl to be easiest.
