> The current code takes everything from the _FactoryManager_ instance - i.e., either the client or the server. By registering a _SessionListener_ one can be notified of session creation **before** the KEX negotiation. The user can then intervene and decide to use a different set of ciphers, MACs, signatures, digests, etc... than default.
> **Note:** If multiple listeners are registered there is no guarantee as to the order of invocation, so if they all attempt to modify the KEX negotiation the result is un-defined.
