This process allows 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.
