Ones that no doubt you would get right ;) Specifically the question I got wrong was: "Cryptographically speaking, what is the main method of building a shared secret over a public medium?" I overlooked diffie-hellman, expecting something more complex and goofed out. My answer was "I wouldn't use a public medium, I'd go out of band to share the secret". Having said that, I understand that crypto is not my area, and that I need to improve, which gives me some good pointers moving forward. Theoretical crypto isn't my thing (infrastructure, malware reversing and other bits of app sec are my thing for want of a better term - as far as crypto goes there are other people in the team that do a better job than me and I accept I'm lazy in this respect so it's a good pointer for me to improve).
