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.
