What is Tutanota and how does it function? Tutanota is an email service that prioritizes user privacy by utilizing end-to-end encryption. They guarantee that the built-in encryption cannot be deciphered by anyone. Tutanota respects user privacy by not tracking them and offers an open-source software, allowing security experts to verify the code protecting user emails. The service is available as an app on iOS and Android platforms, providing a secure and ad-free email experience. It also includes an encrypted calendar with end-to-end encrypted event notifications and reminders. Tutanota minimizes the number of permissions required to maximize user privacy. The email encryption is achieved through symmetric (AES 128) and asymmetric encryption (AES 128 / RSA 2048), and additional security measures such as STARTTLS, Perfect Forward Secrecy, DNSSEC, DANE, DMARC, and DKIM are employed.
