Born in the Blue Ridge; operating out of the Tassajara Ridge: hull&trail is a tradecraft atelier that designs engaging, interactive curricula around cryptography and its role in confronting real-world issues that impact our communities, from social marginalization, to political disinformation, to election integrity.

We're currently building midrange, a web-based field cryptography adventure game featuring springmaus, an authenticated encryption scheme based on an ARX-like Lai-Massey block cipher design, built in-house for optimal learnability and swift deployment. Our books are open. Let's work together.
