ProcessFinalL(const TDesC8 &, TDes8 &, TRequestStatus &)

void	ProcessFinalL	(	const TDesC8 &	aInput,
			TDes8 &	aOutput,
			TRequestStatus &	aRequestStatus
		)	[pure virtual]

Asynchronously Pads aInput to be block aligned using the underlying padding system, the encrypts or decrypts the input data, and appends the result to aOutput

leave: ... Any of the crypto error codes defined in cryptospi_errs.h or any of the system-wide error codes.

Parameters

const TDesC8 & aInput	The input buffer to be encrypted or decrypted.
TDes8 & aOutput	The resulting, padded, processed data is appended to aOutput.
TRequestStatus & aRequestStatus

ProcessL(const TDesC8 &, TDes8 &, TRequestStatus &)

void	ProcessL	(	const TDesC8 &	aInput,
			TDes8 &	aOutput,
			TRequestStatus &	aRequestStatus
		)	[pure virtual]

Encrypts or decrypts aInput and appends the result to aOutput asynchronously

leave: ... Any of the crypto error codes defined in cryptospi_errs.h or any of the system-wide error codes.

Parameters

const TDesC8 & aInput	The input data to be processed.
TDes8 & aOutput	The resulting processed data appended to aOutput.
TRequestStatus & aRequestStatus
