Some other challenges on the website. I'm not eligible, but I'm giving it a shot for fun.

The cipher itself is very easy, but they are looking for more than a $5 wrench. So I can only assume I'm halfway there.

God, it's actually a fair bit of work.


Spoiler for anyone who wants to do it on their own. Here's what I've figured out so far







Original text is Base64 encoded, decode, check hex and you'll see it's a JPG. View the JPG - there is a binary border around the JPG, which after about an hour (at least that's how long it took me, you'll find that it's an encoded link which gives a 4096 key. I'm stuck on that :(

If anyone has any ideas, I'd like to hear!
