Struct CreateFast

Source 
pub struct CreateFast { /* private fields */ }
Expand description

A CreateFast message creates a circuit using no public-key crypto.

CreateFast is safe only when used on an already-secure TLS connection. It can only be used for the first hop of a circuit.

Relays reply to a CreateFast message with CreatedFast on success, or a Destroy message on failure.

This handshake was originally used for the first hop of every circuit. Nowadays it is used for creating one-hop circuits when we don’t know any onion key for the first hop.
