Challenge:
Santa forgot his password from last year for the gift system, all he has is the password hash from the backup database - 0e05910310684507431798973709823129745294. The password is too strong to crack even for his magic mining rigs. His elves are not very good web developers though so it shouldn’t be hard to find a way to log into the app. https://blitzen.bsidesljubljana.si/

Challenge: Santa has encoded a secret text in some weird format. Robots couldn’t decode it, let’s hope that humans and other beings can.
