Constructor & Destructor Documentation

CMacFactory()

CMacFactory ( ) [private]

The class is used as a static class since there is no data or behaviour in the class that depends on object identity. Therefore the default constructor of this class is made private.

CreateAsyncMacL(CAsyncMac *&, const TUid, const CKey &, const CCryptoParams *)

IMPORT_C void CreateAsyncMacL ( CAsyncMac *& aMac,
const TUid aAlgorithmUid,
const CKey & aKey,
const CCryptoParams * aAlgorithmParams
) [static]

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

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

Parameters

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

CreateMacL(CMac *&, const TUid, const CKey &, const CCryptoParams *)

IMPORT_C void CreateMacL ( CMac *& aMac,
const TUid aAlgorithmUid,
const CKey & aKey,
const CCryptoParams * aAlgorithmParams
) [static]

Create a CMac instance (for software based MAC plug-in dll implementation)

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

Parameters

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