Challenge: Santa updated his Christmas carol playlist, but he noticed that the elves are trying to trick him again. He is listening to this song over and over again, but cannot decode it. Please help Santa to solve this audio mystery.

Challenge: Santa has got an essential song locked away in the attached file, but now he forgot the key. He was interested in the basic building blocks of modern cryptography; also he was reading a lot about politics. Can you help him figure out the key so everyone could listen to this song on repeat?

Challenge: While Santa was changing his password he was flying very fast through the sky. Normally, the password is successfully changed when he touches 100 stars (iterations). But this time something went wrong and after touching the 10th star (iteration) one reindeer kicked his computer. Now he missed the remaining 90 stars. Can you help us find what password Santa was typing?
