I'm a cryptographic engineer trying to improve people's privacy.
You can find me online at these locations (activity not guaranteed):

Software
Some of the software I have built and/or maintain:
rage
: A Rust implementation of age file encryption. Also available as a Rust crate!age-plugin-yubikey
: A plugin for age clients which enables files to be encrypted to age identities stored on YubiKeys.- Zcash: a digital currency using zero-knowledge proofs for privacy. I've been
one of the primary maintainers of the
