CSecureChannelServer Class

The CSecureChannelServer class is a helper class (not an interface) that enables a service provider or secure content provider to authenticate an application using the IComponentAuthenticate interface, to encrypt and decrypt data, and to create MAC signatures. The authentication process requires that the application create a CSecureChannelClient object and that the service provider create a CSecureChannelServer object. The CSecureChannelClient and CSecureChannelServer classes are declared in the static link library, Mssachlp.lib. All methods of Windows Media Device Manager, service provider, and secure content provider interfaces can return WMDM_E_NOTCERTIFIED to indicate that the caller has not authenticated successfully.

The CSecureChannelServer class exposes the following methods.

Method	Description
DecryptParam	Decrypts the data contained in a parameter.
EncryptParam	Encrypts the data contained in a parameter.
fIsAuthenticated	Verifies that a secure authentication channel has been successfully established.
GetAppSec	Retrieves the application security levels of the local and remote components.
GetSessionKey	Retrieves the current session key.
MACFinal	Releases the message authentication code (MAC) channel and retrieves a final MAC value.
MACInit	Acquires a message authentication code (MAC) channel.
MACUpdate	Updates the message authentication code (MAC) value with a parameter value.
SACAuth	Establishes a secure authenticated channel between components.
SACGetProtocols	Reports the protocols supported by a component.
SetCertificate	Specifies the certificate and private key of the secure authenticated channel (SAC) server.
SetSessionKey	Sets the session key that is used to communicate with another component.
