- // 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.
