t2′09 Challenge Confusion

Few people pointed out that the size and md5sum of the Challenge did not match. The culprit here was that the size changed when the Challenge was moved from Mac OSX to Linux and thus the md5sum changed as well. The correct size is 1 889 and md5sum d50107540d149eff1d16588dc5a1c1a7. We are very sorry about this - we should have known better.

  1. Just a quick question off topic, is there a reason for not using sha2 instead of md5?

  2. Yes – laziness :)

    In this case we are not that afraid of collisions …
