Taught by j soma

Soma was born in the South, is what someone from the North would say. He cooks for fun, codes for hire, and has more hobbies than can dance on the head of a pin. His work has been featured everywhere from Gawker to The New York Times.

This class might be over, but get first dibs on new sessions and brand-new classes by signing up on our ultra-rad mailing list.

Secrets have always been kept, but they're most fun down on paper.

We'll work our way up from the Caesar cipher to quantum cryptography: surveying history, doing some experiments, and learning how all of this affects us in the now.

Cryptography casts a pretty big net. It shows up in war (cracking the Nazi's Enigma machine), in peace (deciphering ancient languages), and everywhere in between (secret decoder rings!). Daring stories of intrigue and espionage will be making an appearance.

Learn methods for encoding secret messages: pass notes in my class that I'll have no chance of understanding with a one-time-pad, or opt for something less secure and get tripped up by frequency analysis!

A spate of rhetorical questions about Cryptography And You: What's it mean to have your computer password-protected? How does https:// make anything secure, and how can people break into your wireless network? How secure is something like Dropbox?

At the end of this class you will know cool stories and fear passwords.
