Cedric Staub

Software / Security Engineer


Hi, I’m Cedric, a Software Engineer and Engineering Manager specializing in Information Security. I graduated from ETH Zurich in Switzerland with a degree in Computer Science and Information Security. I currently work at Pinterest, and was previously at Square.


I maintain the following open-souce projects:

  • Ghostunnel, a simple TLS proxy with mutual authentication and access control for securing non-TLS services. Supports short-lived certificates, comes with built-in metrics, and works with SPIFFE.

  • Go JOSE, an implementation of the Javascript Object Signing and Encryption (JOSE) standard written in Go. Useful as a building block for the implementation of JOSE-based protocols. Used in Boulder, an ACME CA implementation that powers Let’s Encrypt.

For other open-source projects I work on, see my GitHub profile.
