I’m Joachim Hendrik Schipper; after some research in cryptography, I now work as a developer in “Crypto & High Security” at Fox-IT.

Should you wish to contact me, you may find it most convenient to send an e-mail (pgp).

You can find my CV here or on LinkedIn. I am also active on Hacker News and various (OpenBSD) mailing lists. You can find some of my code on GitHub.

After studying abstract algebra, I worked on (leakage-resilient) cryptography (introduction). I have recently TA’ed Introduction to Modern Cryptography at the University of Amsterdam.

In the months before I left for the US, I worked as a system administrator (Linux, some Windows) for GridLine.
I occasionally write some programs, usually in C or Python.
