Dear Jeff!
I changed the mentioned code as below:
#include "stdafx.h"
#include "rsa.h"
#include "osrng.h" // PRNG
#include "hex.h" // Hex Encoder/Decoder
#include "files.h" // File Source and Sink
#include "filters.h"
int main(int argc, char* argv[])
{
try
{
// Files
std::string PublicKeyFile = "key.pb";
std::string SignedFile = "message.sig";
std::cout << "Public Key File: " << PublicKeyFile.c_str() <<
std::endl;
std::cout << "Signature File: " << SignedFile.c_str() <<
std::endl;
// Message M
std::string message = "Yoda said, Do or Do Not. There is not
try.";
// Load Public Key
CryptoPP::FileSource pubFile( PublicKeyFile.c_str(), true,
new CryptoPP::HexDecoder );
// Verifier Object
CryptoPP::RSASSA_PKCS1v15_SHA_Verifier pub(pubFile);
// Intialize File Source
CryptoPP::FileSource SignatureFile( SignedFile.c_str(),
true, new CryptoPP::HexDecoder);
// Sanity Check
if (SignatureFile.MaxRetrievable() != pub.SignatureLength())
{ throw std::string( "Signature File Size Problem" ); }
CryptoPP::SecByteBlock signature( pub.SignatureLength() );
SignatureFile.Get( signature, signature.size() );
// Prepare Verifier
CryptoPP::VerifierFilter *verifierFilter =
new CryptoPP::VerifierFilter(pub);
verifierFilter->Put(signature, pub.SignatureLength());
// Invoke Verifier
// CryptoPP::StringSource( message, true, verifierFilter );
CryptoPP::StringSource( message, true, new Redirector
(verifierFilter,PASS_EVERYTHING));
// Paydirt
if( false == verifierFilter->GetLastResult() )
{ throw std::string( "Signature Verification Failed" ); }
std::cout << std::endl << "Signature Verified" << std::endl;
} // try
catch( CryptoPP::Exception& e ) {
std::cerr << "Error: " << e.what() << std::endl;
}
catch (...) {
std::cerr << "Unknown Error" << std::endl;
}
return 0;
}
But I get this errors:
Compiling...
RSASignVer.cpp
d:\rsasignver.cpp(64) : error C2061: syntax error : identifier
'Redirector'
d:\rsasignver.cpp(64) : error C2065: 'PASS_EVERYTHING' : undeclared
identifier
d:\rsasignver.cpp(64) : error C2143: syntax error : missing ';' before
')'
d:\rsasignver.cpp(64) : error C2143: syntax error : missing ';' before
')'
RSASignVer - 4 error(s), 0 warning(s)
What's the problem?
How do you change this code to work properly?
Best Regards.
Gary
