Saron Yitbarek of CodeNewbie hosted a friendly cryptoparty for beginners called "Protect Yo'Self! A day of workshops on security and online privacy" that I was thrilled to be able to lead a workshop at. I wrote a lecture, activities, and curriculum for a section on encryption, which I led four times in a row from noon to 4PM. Phew!

An Encryption Workshop for Beginners
If there's enough popular demand, I may work to turn my lecture notes into a series of blog posts.
