ExchangeKeys Method
Causes the class to exchange a new set of session keys on the specified connection.
Object Oriented Interface
public function doExchangeKeys($connectionid);
Procedural Interface
ipworkssftp_sftpserver_do_exchangekeys($res, $connectionid);
Remarks
SSH key renegotiation can be initiated by either end of an established SSH connection. ExchangeKeys allows the server to start such a renegotiation with the client. During this process, SSHStatus events will fire containing updates regarding the key negotiation process.
The SSH 2.0 specification recommends that key renegotiation be done once for 2 gigabytes (GB) of data processed by the connection, or once every day. This makes it more difficult to break the security of data-intensive or long-lived connections.
