Let's take a look at a few examples of email communication with Autocrypt.

Or, the user has to send an encryption password with a hint to the non-Liverado user in case he wants to send them an encrypted messageĪs you can probably guess, none of this is ideal and it meant that we had to encrypt emails that you get from non-Liverado services "at rest", but with Autocrypt, you'll be able to get complete and, more importantly, convenient E2EE of emails.

The message is sent to the email server in plaintext which encrypts it for the user, stores it and sends the plaintext to non-Liverado users (for non-Liverado recipients).

The message has to be sent in plaintext to the email server, which then encrypts the message for the Liverado user and sends the plain message to non-Liverado users (If the recipients are both Liverado and non-Liverado users).

So far, sending an encrypted email message to non-Liverado users meant that either:

This was something that was on our roadmap for a while now and we are proud to finally be able to offer full end-to-end encryption to our users even when they are sending emails to someone on non-Liverado email service. So far, Autocrypt has been implemented by several email services (see the table below) and now Liverado is joining them as we've finally implemented Autcrypt into our service. This is because the header contains the encryption preferences and the key materials necessary for the key exchange between users. This problem can be solved with Autocrypt, which is a cryptographic protocol that can enable encryption between separate email services.Īutocrypt uses OpenPGP standard and actually requires no support from email providers apart from keeping the Autocrypt-specific header fields. The reason behind this is that they need to exchange keys securely. If the sides are using different email providers, however, then the emails sent between them cannot be encrypted, at least not without some juggling. One of the biggest problems end-to-end encrypted email users face is the fact that encryption only works if both the sender and the recipient are using the same email service.
