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…

Built an offline encryption tool for people who don't trust cloud services or hardware wallets. Paranoid Qrypto runs completely offline (air-gapped). You type your seed phrase on an offline device, and it encrypts it using Argon2id + AES-256-GCM. The encrypted file can be stored anywhere USB, cloud, printed as QR code without exposing your keys. Why this was build: Hardware wallets cost $100-200 and are single points of failure * Cloud solutions require trusting a third party * Paper backups have no protection if found Technical details: * Runs in browser with no server calls * All…
