Tuta Mail enables TutaCrypt, a protocol to exchange messages using quantum-safe encryption.

Just in time for 10 years of Tuta/Tutanota, we are launching the most significant security upgrade of Tuta Mail with TutaCrypt. This groundbreaking post-quantum encryption protocol will secure emails with a hybrid protocol combining state-of-the-art quantum-safe algorithms with traditional algorithms (AES/ECC) making Tuta Mail the world’s first email provider that can protect emails from quantum computer attacks.

    Quite a lot of cryptography detail in their blog post, not all of which do I understand. Curious to find out what the community thinks of this …

    For instance:

    We’ve re-built the Tuta cryptographic protocol from the ground up and are now upgrading our encryption using quantum-resistant algorithms together with conventional algorithms (Kyber in combination with AES 256 and ECDH x25519 in a hybrid protocol) for our asymmetric public key encryption of emails

    I know Bruce Schneier says rolling your own Crypto is hard and most will get it wrong. So is it concerning that they made their own encryption protocol?
