Hi HN, we are the developers from Tuta (formerly Tutanota), the German end-to-end encrypted email provider, and we recently released the world's first post-quantum encryption for email. We have included a full technical write-up of the cryptography involved in these changes and we have released it for open public review. This document specifies TutaCrypt, a protocol designed for hybrid email encryption in Tuta Mail. The protocol combines a classical Elliptic-Curve-Diffie-Hellman key exchange with a post-quantum KEM. The goal is to replace the usage of RSA in Tuta Mail. In the remainder of…

I’ve developed a new public-key encryption scheme (DIAC) that uses multidimensional, high-precision complex keyspaces and a modular trapdoor function for ultra-high entropy and quantum resistance. The code, benchmarks, and research paper (PDF) are all open-source: https://osf.io/mvkcq/ Would love feedback, questions, or cryptanalysis!
