PPC - 100 Points
Those spies learned in university that prime numbers are essential for cryptography. Unfortunately, they got in wrong.
A tar.gz file is given.
We started this challenge after the PPC 100_1 so we knew how to proceeds.
Every filename was an integer and the content a single hexadecimal character
If the description tell us that they got prime numbers in wrong, maybe we should concat the content of prime filename.
After some fight with the CTF’s website (it was reporting wrong flag :( ) we finally got our points!
