InverseSignLC(const CRSASignature &)

HBufC8 *

InverseSignLC

(

const CRSASignature &

aSignature

)

const [pure virtual]

Performs a decryption operation on a signature using the public key.

This is the inverse of the sign operation, which performs a encryption operation on its input data using the private key. Although this can be used to verify signatures, CRSAVerifier::VerifyL should be used in preference. This method is however required by some security protocols.

Parameters

const CRSASignature & aSignature

The signature to be verified

MaxOutputLength(void)

TInt

MaxOutputLength

(

void

)

const [pure virtual]

Gets the maximum size of output that can be generated by this object.

Parameters

void

VerifyL(const TDesC8 &, const CRSASignature &)

IMPORT_C TBool	VerifyL	(	const TDesC8 &	aInput,
			const CRSASignature &	aSignature
		)	const [virtual]

Verifies the specified digital signature

Parameters

const TDesC8 & aInput	The message digest that was originally signed
const CRSASignature & aSignature	The signature to be verified
