The 2Warm Challenge is worth 50 Points and looks quite easy at the first glance.
The Challenge is straight forward:

Can you convert the number 42 (base 10) to binary (base 2)?

I guess we can do that. The fastest way would be calculating it by hand. If you don know how to do that it’s okay. There are plenty of pages on the web about this topic. My attempt is shown below.

It’s 32+8+2 = 42 🙂

But the more easy way is to use any online-tool you like. f.e. cyberchef. (https://gchq.github.io/CyberChef/) Get the recipe together and slap the number in.

Submit the flag (They want the shortened binary form without the first two bits for an entire byte) – Hooooray, another 50 Points!
