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.

Definition at line 47 of file pubkey.cpp.

size_t TF_SignerBase::SignAndRestart	(	RandomNumberGenerator &	rng,
		PK_MessageAccumulator &	messageAccumulator,
		byte *	signature,
		bool	restart = `true`
	)		const

virtual

Sign and restart messageAccumulator.

Parameters

rng	a RandomNumberGenerator derived class
messageAccumulator	a pointer to a PK_MessageAccumulator derived class
signature	a block of bytes for the signature
restart	flag indicating whether the messageAccumulator should be restarted

Returns: actual signature length
