Hacking Week 2015
posted May 2015
The Hacking week just started, it's a CTF that happens over a week.
You'll find challenges about crypto, network, forensic, reverse and exploit.
And also, I have a challenge up there in the crypto challenge ^^
It's in french here: http://hackingweek.fr/challenges/ (click on "voir" next to crypto 4)
basically Alice encrypted the secret, you have to find what the secret is. What you have is a key that shares the same modulus as Alice.
