I love CTFs and though I can’t take part in a lot of them, I make it a point to always play in Secured By Design’s CTF036. Four years in a row now and the events just keep getting better!
I was invited to give a small talk again, this time covering the basics of PKI: public key infrastructure. In short, PKI is one of the ways to solve the challenge of “trust” in an environment: how can you trust that someone or something really is whom they claim to be? We were very much cramped for time, so I had to try and smush everything into half an hour! While the talk went smoothly, I’m not entirely happy: there was just too much info in too little time. And I didn’t even cover it all!
