TutaCrypt, post-quantum encryption protocols for securing emails [pdf] is a business in show hn launch.

Profile

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 this document we describe some preliminaries such as the cryptographic primitives used. We define the core

Within the show hn launch space, the company focuses on its core offering rather than a broad product line.

Directory data places it at the Show HN launch stage.
