Last-Minute update for Ex4

Written: 26.06.2018 20:00 Written By: Frederik Möllers

Hi all,

a big sorry from my side, but there has been a mixup in the encrypted message on Exercise 4. The binary data was mixed so that every two bytes were swapped. If you managed to extract the AES key but failed to decrypt the message from the sheet, try it again with the following data:

8feb0333433b0f660c8a7215e95eeecc
27e47a35d75c0eda16aa42e30752e407
50032f405358c7f0e07650480ad42795
0af6a7293a8e37515bad8a29b3f129af
54ee5ea350e880a74f3848371db88c72
6fffe3f2b437319815199d6eeab3c0b6
c2c6d80153d82cafba8c1933090504ad
10ca8c221dcef3fd2a8f40cae8d5b2e3
ca4f2d101a540514ca68cef6896e6ec1
4fec604ee5219124f815e59e359c785c
c321e6f70a8df9d534996dcf96812e60
665ffcd15e94983e82cdc62a40cd34a9

If your submission is correct up to the point where you decrypt the message, you will of course get full points.

Sorry for the mistake and see you tomorrow,
Frederik
