Details on encryption scheme?

[worldveil]

Hi there!

From the WalletConnect docs (which are wonderful, by the way), I am trying to understand a few things.

It appears Bridge server generates a public/private key pair that uses this code.

My understanding is that the clients want to each encrypt/decrypt with symmetric key to talk to each other, which means then both parties would need access to the key, and the server would need to discard the key after generation. Is this correct, or do clients generate keys somehow?

In which message of the WalletConnect protocol and which fields are these keys passed to clients?

Curious to learn more details on this.
