I gave my first (and probably last) presentation to the BYU Unix Users Group tonight. I’m finally getting over whatever has made me sick (flu or something), so I was almost completely lucid. I started talking about hash functions, symmetric key encryption, and public-key encryption. I then talked about how those ideas are used in encrypted email, and certifcates. I then gave a very lame explanation of SSL/TLS. After that, we discussed some different attacks, and common security mistakes that people make. Overall, I think it was a good hour-long presentation.

Here’s the slides:
