Are my communications via the Diode Network encrypted?

While all sorts of communication can be accomplished at a low level with the Diode Network (encrypted and non-encrypted), Diode Collab, Diode CLI, and other applications Diode deploys use 256bit end-to-end encryption - specifically the elliptic curve secp256k1 domain parameter for Diode Network server connections and E2E connections.

The Diode CLI has E2E encryption turned on by default, but can be controlled via the “-e2e=<true/false>” parameter.
