◆ InputRecoverableMessage()

void TF_SignerBase::InputRecoverableMessage	(	PK_MessageAccumulator &	messageAccumulator,
		const byte *	recoverableMessage,
		size_t	recoverableMessageLength
	)		const

virtual

Input a recoverable message to an accumulator.

Parameters

messageAccumulator	a reference to a PK_MessageAccumulator
recoverableMessage	a pointer to the recoverable message part to be signed
recoverableMessageLength	the size of the recoverable message part

Implements PK_Signer.
