// CSecurity - class on the client side for handling security handshaking. A
|
|
// derived class for a particular security type overrides the processMsg()
|
|
// method.
|
|
|
|
// processMsg() is called first when the security type has been decided on, and
|
|
// will keep being called whenever there is data to read from the server. It
|
|
// should return false when it needs more data, or true when the security
|
|
// handshaking is over and we are now waiting for the SecurityResult message
|
|
// from the server. In the event of failure a suitable exception should be
|
|
// thrown.
|
|
//
|
|
// Note that the first time processMsg() is called, there is no guarantee that
|
|
// there is any data to read from the CConnection's InStream, but subsequent
|
|
// calls guarantee there is at least one byte which can be read without
|
|
// blocking.
|
|
//
|
|
// description is a string describing the level of encryption applied to the
|
|
// session, or null if no encryption will be used.
