How Prime Numbers Keep the Internet Secure (RubyConf 2020)


You may not know it, but you use prime numbers every day. They play a major role in internet security in the form of encryption.

In this talk, you will learn the inner workings of how the internet uses prime numbers to keep your data private as it travels over the wire. We will cover topics such as symmetric and asymmetric encryption, and why prime numbers are just so damn hard to crack. By the end, you will understand how to encrypt and decrypt data yourself with just the Ruby standard library.

So come join me as we demystify HTTPS using code, color theory, and only a pinch of math 🤓.


I gave this presentation at RubyConf2020.
