Let's Go Quantum - Sam Burns

As quantum computing advances, classical encryption will become increasingly vulnerable. Go 1.23 is the first version of the language to introduce some post-quantum encryption features, with more to come.
This talk will start off with a very light overview of quantum computing. We will cover what it is, and check in on the current state of the art, as well as why this is relevant to encryption. We will take a look at hardware and software available for developers to use quantum computers right now, and why the store-now-decrypt-later threat model makes this the right time to begin introducing post-quantum encryption in Go.
Post-quantum encryption is being introduced to Go 1.23, starting with a Key Encapsulation Mechanism for use with TLS. It is highly likely new hashing algorithms and other features will be rolled out slowly in forthcoming versions. Join us for a mercifully lightweight introduction to quantum computing, a discussion of the new features, and how to use them - and let's go quantum!
