Member Functions Documentation

InverseSignL(HBufC8 *&, const CCryptoParams &)

void	InverseSignL	(	HBufC8 *&	aOutput,
			const CCryptoParams &	aSignature
		)	[pure virtual]

Unsign the signature

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

Parameters

HBufC8 *& aOutput	The unsigned hash
const CCryptoParams & aSignature	The signature of the hash

VerifyL(const TDesC8 &, const CCryptoParams &, TBool &)

void	VerifyL	(	const TDesC8 &	aInput,
			const CCryptoParams &	aSignature,
			TBool &	aVerificationResult
		)	[pure virtual]

Verify the signature

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 hash of the message to be verified
const CCryptoParams & aSignature	The signature of the hash
TBool & aVerificationResult	Indicates the success or failure of the verification
