Member Functions Documentation

InternalizeL(RReadStream &)

void InternalizeL ( RReadStream & aStream ) [virtual]

Internalize this object from the supplied stream.

Parameters

RReadStream & aStream Stream to read CSymmetricCipherCharacteristics from.

IsOperationModeSupported(TUid)

TBool IsOperationModeSupported ( TUid aOperationMode ) const

Determines whether an operation mode (e.g. HMAC) is supported by the plug-in by searching through iSupportedOperationModes for the UID value corresponding to the aOperationMode parameter.

Parameters

TUid aOperationMode The UID of the operation mode to test

IsPaddingModeSupported(TUid)

TBool IsPaddingModeSupported ( TUid aPaddingMode ) const

Determines whether a padding mode (e.g. PKCS7) is supported by the plug-in by searching through iSupportedPaddingModes for the UID value corresponding to the aPaddingMode parameter.

Parameters

TUid aPaddingMode The UID of the padding mode to test.

NewL()

CSymmetricCipherCharacteristics * NewL ( ) [static]

Create a new instance of CSymmetricCipherCharacteristics .

NewLC()

CSymmetricCipherCharacteristics * NewLC ( ) [static]

Create a new instance of CSymmetricCipherCharacteristics . Leave it on the cleanup stack.
