![]() ![]() In addition to end-to-end encryption, it also strips messages of IP addresses. Meanwhile, Proton Mail offers complete anonymity to its users, too. Tutanota strips IP address information from its messages, making it impossible for anyone to trace the message back to the user, at least using the IP. Like Tutanota, Proton Mail’s encryption prevents even Proton Mail itself from decrypting it and reading your messages. It uses OpenPGP, an industry-standard email encryption algorithm that has several weaknesses mentioned above – no encryption of subject lines, and no perfect forward secrecy. Proton Mail also uses end-to-end symmetrical encryption – RSA 2048-bit for user-to-user emails, AES 256-bit for user-to-non-user emails. Tutanota also encrypts your address book and your calendar. It also offers perfect forward secrecy, meaning hacking a past session doesn’t give a cybercriminal access to future sessions. Even Tutanota can’t decrypt your messages. The service uses the same algorithms as PGP, but encrypts subject lines as well as the email body above that. Tutanota offers end-to-end symmetrical encryption – RSA 2048-bit for user-to-user emails, AES 128-bit for user-to-non-user emails. ![]()
