Robert J. Hansen

Black Hat USA and DEF CON speaker, co-inventor of language-theoretic security

There are at least two different Robert Hansens in the computer security community. I’m Robert J. Hansen, co-inventor of language theoretic security, speaker at Black Hat USA, DEF CON, and OSCON. I’m not Robert “RSnake” Hansen, who has also spoken at Black Hat USA and DEF CON. From all I hear he’s a nice guy and I wish him well, but I’m not him.

Still interested?

I maintain:

  • Quickerhash, a crossplatform hashing tool meant specifically for educators and trainers
  • Djinni, a header-only C++ library for simulated and compressed annealing
  • rpass, a drop-in replacement for Ted Ts’o’s pwgen tool
  • osslsigncode, a Linux tool to put Authenticode signatures on Windows binaries
