                        This process will allow you to export the keys for messages
                        you have received in encrypted rooms to a local file. You
                        will then be able to import the file into another Matrix
                        client in the future, so that client will also be able to
                        decrypt these messages.
                    </p>
                    <p>
                        The exported file will allow anyone who can read it to decrypt
                        any encrypted messages that you can see, so you should be
                        careful to keep it secure. To help with this, you should enter
                        a passphrase below, which will be used to encrypt the exported
                        data. It will only be possible to import the data by using the
                        same passphrase.
