Trythis0ne is a free project that offers you to challenge yourself in different subjects, such as Hacking, Cracking, Crypto & Stegano, Reversing, Programming and much more.
I played with some challenges from trythis0ne (tt0) and will expose the solution here, they're the simplest ones but I hope it can help anyone with difficulties.. It's not nice to look for the resolution before trying to solve the problem and consulting the tt0 forum.
I'm not from tt0 staff, and if this blog offends anyone from the staff, please mail-me.
