Overview

An implementation of a key-exchange strategy specifically for unit tests. (This strategy would never really work against a real SSH server–it makes too many assumptions about the server’s response.)

This registers itself with the transport key-exchange system as the “test” algorithm.

#exchange_keys ⇒ Object

Exchange keys with the server. This returns a hash of constant values, and does not actually exchange keys.
