Convenient End-to-End Encryption for E-Mail
Autocrypt-capable mail apps work with any e-mail provider. You and your friends can use your existing e-mail addresses.
Autocrypt is an open specification for e-mail encryption. Under the hood, it uses OpenPGP and other e-mail standards.
What is Autocrypt?
Autocrypt is a set of guidelines for developers to achieve convenient end-to-end-encryption of e-mails. It specifies how e-mail programs negotiate encryption capabilities using regular e-mails.
For users, Autocrypt Level 1 offers single-click, opt-in encryption, eases encrypted group communications, and provides a way to setup encryption on multiple devices.
