Educated Guesswork

I'm Eric Rescorla.

Currently working at Google on AI Security. Formerly: Chief Technologist for the Center for Forecasting and Outbreak Analytics at the United States Centers for Disease Control and Prevention; Chief Technology Officer, Firefox. All opinions here are my own and not those of any current or former employer.

I've contributed extensively to many of the core security protocols used in the Internet. Some stuff I've done includes: editor of TLS 1.3, which secures the vast majority of Web traffic; co-founder of Let’s Encrypt, a free and automated certificate authority that now issues around three million certificates a day; a bunch of work on WebRTC, which allows anyone to videoconference directly from their browser (used inWebEx, Teams, Meet, etc.). More recently, I've been working on the development of technologies for privacy preserving measurement and privacy preserving advertising.

Most of the material here will be about tech, tech policy, the intersection of tech and society, tech, science fiction, running, or running tech.
