Encrypting Data with Guard

The Autocrypt standard has been developed to provide an automatic E-Mail encryption. This is done as follows:

• Each E-Mail sent includes the public key of the sender in the E-Mail header. This key will be imported automatically or manually by the recipient.

Autocrypt has the following limitiations:

• There is no check for automatically imported keys to see whether they are correct or a fake.

• For this reason, an automatically imported key is not used for verifying the sender's signature.

To manage Autocrypt keys and verify them later, you have the following options:

• Importing Autocrypt keys

• Managing Autocrypt keys

• Transferring Autocrypt keys to other clients
