Member Functions Documentation

AddAuthTagToPacketL(TUint8 *)

voidAddAuthTagToPacketL(TUint8 *aSrtpPacketPtr)[private]

Parameters

TUint8 * aSrtpPacketPtr

AddEflagAndSrtcpIndex(TUint8 *)

voidAddEflagAndSrtcpIndex(TUint8 *aSrtcpPacketPtr)[private]

Parameters

TUint8 * aSrtcpPacketPtr

AddMKIToPacket(TUint8 *)

voidAddMKIToPacket(TUint8 *aSrtpPacketPtr)[private]

Parameters

TUint8 * aSrtpPacketPtr

AddReplayIndex()

voidAddReplayIndex()[private]

AuthenticateL()

voidAuthenticateL()[private, virtual]

CalculateAuthTagL()

HBufC8 *CalculateAuthTagL()
Calculate authentication tag for an RTP packet. Authentication is based on the current TSRTPAuthAlg algorithm setting in CryptoContext If the operation fails, the function leaves with a system error code.
leave
KErrNone if success, system-wide error code otherwise, KErrNotFound means that authentication tags dont match
