// 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 until either it returns false, indicating authentication/security
|
|
// failure, or it returns with done set to true, to indicate success.
|
|
//
|
|
// 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.
