AuthKeyLength()

IMPORT_C TUint AuthKeyLength ( ) const

ConstructL(const TDesC8 &, const TDesC8 &)

void ConstructL ( const TDesC8 & aKey,
const TDesC8 & aMKI
) [private]

Parameters

const TDesC8 & aKey
const TDesC8 & aMKI

EncrKeyLength()

IMPORT_C TUint EncrKeyLength ( ) const

MKI()

IMPORT_C const TDesC8 & MKI ( ) const

MasterKey()

IMPORT_C const TDesC8 & MasterKey ( ) const

NewL(const TDesC8 &, const TDesC8 &, TUint, TUint)

IMPORT_C CSRTPMasterKey * NewL ( const TDesC8 & aKey,
const TDesC8 & aMKI,
TUint aN_E =  KSRTPDefSessionEncryptionKeyLength ,
TUint aN_A =  KSRTPDefSessionAuthenticationKeyLength
) [static]
Two-phased constructor. CSRTPCryptoContext takes the ownership of MasterKey and MasterSalt
leave
KErrNone if success, system-wide error code otherwise

Parameters

const TDesC8 & aKey The master key value. Local copy is made.
const TDesC8 & aMKI The master key identifier value. Local copy is made. MKI key is optional so if there is no MKI key then gives empty string "".
TUint aN_E =  KSRTPDefSessionEncryptionKeyLength The bit length of the encryption key
TUint aN_A =  KSRTPDefSessionAuthenticationKeyLength The bit length of the authentication key

NewLC(const TDesC8 &, const TDesC8 &, TUint, TUint)

IMPORT_C CSRTPMasterKey * NewLC ( const TDesC8 & aKey,
const TDesC8 & aMKI,
TUint aN_E =  KSRTPDefSessionEncryptionKeyLength ,
TUint aN_A =  KSRTPDefSessionAuthenticationKeyLength
) [static]
Two-phased constructor. CSRTPCryptoContext takes the ownership of MasterKey and MasterSalt
leave
KErrNone if success, system-wide error code otherwise

Parameters

const TDesC8 & aKey The master key value. Local copy is made.
const TDesC8 & aMKI The master key identifier value. Local copy is made.
TUint aN_E =  KSRTPDefSessionEncryptionKeyLength The bit length of the encryption key
TUint aN_A =  KSRTPDefSessionAuthenticationKeyLength The bit length of the authentication key

Valid()

IMPORT_C TBool Valid ( ) const

operator=(const CSRTPMasterKey &)

const CSRTPMasterKey & operator= ( const CSRTPMasterKey & aKey ) [private]

Parameters

const CSRTPMasterKey & aKey
