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

IMPORT_C CSRTPMasterKey *NewL(const TDesC8 &aKey,
const TDesC8 &aMKI,
TUintaN_E =  KSRTPDefSessionEncryptionKeyLength ,
TUintaN_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 & aKeyThe master key value. Local copy is made.
const TDesC8 & aMKIThe 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,
TUintaN_E =  KSRTPDefSessionEncryptionKeyLength ,
TUintaN_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 & aKeyThe master key value. Local copy is made.
const TDesC8 & aMKIThe 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()
