Welcome to the DEFCON 201 Crypto CTF Practice Challenge!

For over two years we have been planing running our own Wargames and CTF to help people develop their hacking skills. While progress is still being made (we plan to launch our own in Winter 2019), DC201 will also occasionally enter into various online CTF Tournaments to test our skills and to get a sample on how one is set up so we have a blueprint in creating our own.

This Friday, from September 20th 10:00 PM EST to September 22nd 10:00 PM EST, we invite all DEFCON 201 Members, Attendees and Fans to help us hack the Crypto CTF 2019!

NOTE: This is happening RIGHT after our DEFCON 201 Meet Up for September 2019 closes! If you are in New Jersey and want to get the log-in and/or prepare for this CTF check out our meet up here:
