Want to become certified RCEH?

Super simple: get at least 70% of the total points (which is 1234 points at the moment). With this certification, you will be able to buy a RCEH token that will be available on the shop. The RingZer0 Certified Elite Hacker (RCEH) certification is a highly technical certification. Anyone holding the RCEH title is a highly skilled hacker.

Once you get your RCEH title you can proudly use the certified logo and show to the rest of the world that you successfully managed to solve several hacking challenges on the RingZer0 CTF.
