Ju Liu

I make sourdough pizza from scratch

Ju was born in China, moved to Italy as a kid, grew up eating a lot of pasta, and started messing around with computers. He now lives in London and works for NoRedInk. He loves to solve hard problems and build amazing products. When he’s not doing that, he’s probably rock climbing.

The Enigma machine was an encryption device that was used by German forces during WW2 to send secret messages. In this talk, we will explain exactly how the encryption process works and go through an implementation of it in Elm. We will demonstrate how to encrypt and decrypt a message. Then we will go over the weaknesses that made it exploitable by Alan Turing and the other fine folks in Bletchley Park. By the end of the talk, you'll be able to point out all the inaccuracies in "The Imitation Game".
