Tuta Mail adds new quantum-resistant encryption to protect email
2024-03-11 21:21

Tuta Mail has announced TutaCrypt, a new post-quantum encryption protocol to secure communications from powerful and anticipated decryption attacks.

Tuta Mail is an open-source end-to-end encrypted email service with ten million users.

Today, Tuta announced the launch of TutaCrypt, a new protocol designed to protect currently exchanged communications from 'harvest now, decrypt later' attacks.

TutaCrypt encryption generates two key pairs for Tuta Mail accounts: an X25519 key pair for the ECDH and a Kyber-1024 key pair for key encapsulation.

These secrets feed into a key derivation function, creating a secure message key for encryption and decryption.

New Tuta Mail accounts will get TutaCrypt upon creation, and existing users will get the superior protocol through a gradual key rotation that will take place over the next period.
