Detailed Description

The Factory to create synchronous and asynchronous Mac instances

Create a CAsyncMac instance (for hardware based MAC plug-in dll implementation)

leave: KErrNone if successful; otherwise, leaves with a system wide error code.

Parameter	Description
aMac	The pointer to CMac. This will be initialised with the plug-in implementation of the desired MAC algorithm.
aAlgorithmUid	The specific MAC algorithm desired for evaluation of MAC value. e.g. MD2, SHA1 or AES-XCBC-MAC-96, AES-XCBC-PRF-128
aKey	Symmetric key for calculating message authentication code value.
aAlgorithmParams	The parameters those are specific to a particular MAC algorithm. This is for extendibility and will normally be null.
