Detailed Description

abstract base class for public-key verifiers.

A verifier is also a public verification key. It contains both the key and the algorithm to perform the verification.

Member Function Documentation

bool PK_Verifier::Verify ( HashModule * messageAccumulator, const byte * signature ) const [pure 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 in VerifierTemplate, and VerifierWithRecoveryTemplate. Referenced by VerifierFilter::MessageEnd(), and VerifyMessage().

bool PK_Verifier::VerifyMessage ( const byte * message, unsigned int messageLen, const byte * sig ) const [virtual]

check whether sig is a valid signature for message. Precondition: size of signature == SignatureLength() Definition at line 478 of file cryptlib.cpp.
