History

Tutanota is derived from Latin and contains the words "tuta" and "nota" which mean "secure message". Founded in 2011 in Hannover, Germany, Tutao GmbH belongs to one of the few providers, who completely provide end-to-end encrypted emails.

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.

In 2014, the software was open-sourced and can be reviewed by externals on GitHub.

Encryption

Tutanota offers end-to-end encryption for emails sent from one Tutanota user to another. Tutanota also encrypts all emails and contacts. 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. 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.
