Member Function Documentation

template<class F, class H> HashModule * VerifierWithRecoveryTemplate< F,H >::NewLeftoverMessageAccumulator ( const byte * signature ) const [virtual]

create a new HashModule to accumulate leftover message. Reimplemented from PK_VerifierWithRecovery. Definition at line 351 of file pubkey.h.

template<class F, class H> unsigned int VerifierWithRecoveryTemplate< F,H >::PartialRecover ( HashModule * messageAccumulator, byte * recoveredMessage ) const [virtual]

partially recover a message from its signature, return length of recoverd message, or 0 if signature is invalid. Preconditions: \begin{itemize} \item leftoverMessageAccumulator was obtained by calling NewLeftoverMessageAccumulator(signature) \item HashModule::Final() has not been called on leftoverMessageAccumulator \item length of signature == SignatureLength() \item size of recoveredMessage == MaximumRecoverableLength() \end{itemize} Reimplemented from PK_VerifierWithRecovery. Definition at line 359 of file pubkey.h.

template<class F, class H> unsigned int VerifierWithRecoveryTemplate< F,H >::Recover ( const byte * signature, byte * recoveredMessage ) const [virtual]

recover a message from its signature, return length of message, or 0 if signature is invalid. This function should be equivalent to PartialRecover(NewLeftoverMessageAccumulator(signature), recoveredMessage). Preconditions: \begin{itemize} \item length of signature == SignatureLength() \item size of recoveredMessage == MaximumRecoverableLength() \end{itemize} Reimplemented from PK_VerifierWithRecovery. Definition at line 366 of file pubkey.h.

template<class F, class H> bool VerifierWithRecoveryTemplate< F,H >::Verify ( HashModule * messageAccumulator, const byte * signature ) const [virtual]

check whether sig is a valid signature for messageAccumulator, and delete messageAccumulator. Preconditions: \begin{itemize} \item messageAccumulator was obtained by calling NewMessageAccumulator() \item HashModule::Final() has not been called on messageAccumulator \item length of signature == SignatureLength() \end{itemize} Reimplemented from PK_Verifier. Definition at line 342 of file pubkey.h.
