 // TMsgAuth1LoginHL.h

// AuthServer messages implementing the Auth1 Family login Half-Life protocol.
// This header/source implements messages:
//	Auth1LoginRequestHL
//	Auth1ChallengeHL
//	Auth1ConfirmHL
// It also included the Auth1LoginReply which is implemented in its own header
// and source module (it is shared).

// Auth1LoginRequestHL begins login for Half-Life and is sent from the Client to
// the AuthServer.

// Auth1ChallengeHL is sent in response to Auth1LoginRequest from the AuthServer
// to the client.

// Auth1ConfirmHL is sent in response to Auth1ChallengeHL from the Client to the
// AuthServer.

// Auth1RefreshHL is from the Client to the AuthServer to request extension of an
// Login session and AuthCertificate.

// Auth1LoginReply is sent in response to Auth1ConfirmHL from the AuthServer
// to the client and completes the login. It is also sent in response to
// Auth1RefreshHL, extending the login session.
