Tutanota is an open-source end-to-end encrypted email software and freemium hosted secure email service. Its business model excludes earning money through advertisement relying solely on donations and Premium subscriptions.
As of March 2017, Tutanota had over 2 million users.
The goal of the developers for Tutanota is to fight for email privacy. Their vision gained even more importance, when Edward Snowden revealed NSA's mass surveillance programs like XKeyscore in July 2013.
Tutanota offers end-to-end encryption for emails sent from one Tutanota user to another. Tutanota also encrypts all emails and contacts.[unreliable source] Tutanota uses a standardized, hybrid method consisting of a symmetrical and an asymmetrical algorithm - AES with a length of 128 bit and RSA with 2048 bit.[unreliable source] To external recipients who do not use Tutanota a notification is sent with a link to a temporary Tutanota account. After entering a previously exchanged password, the recipient can read the message and reply end-to-end encrypted.[unreliable source]
Users of Premium accounts can use their own domains with Tutanota.
