Allow asymmetric Keys

What type of request is this?

New feature idea

Clear and concise description of the feature you are proposing

Currently, the security of the transmission relies on the password being transported through another secure method.

Using asymmetric keys, it would be possible to exchange public keys over a channel that is not secure but trustworthy.

For this purpose, a potential recipient would first generate a key pair, which is stored locally in their browser. They would only share the public key with the sender.
