Hello,
It seems that the RsaSignFile method (taken from test.cpp) returns
different values depending on the compilation mode (release or debug).
While the method works ok in debug it doesn't seem to work in release
(means returns a wrong value).
Here are the 2 slightly modified methods (for signing and verifying):
static std::string sign(const std::string& message, const std::string&
priv_key)
{
std::string sig;
CryptoPP::StringSource source(priv_key, true, new
CryptoPP::HexDecoder());
CryptoPP::RSASS<CryptoPP::PKCS1v15, CryptoPP::SHA>::Signer
signer(source);
CryptoPP::StringSource(message, true, new
CryptoPP::SignerFilter(CryptoPP::AutoSeededRandomPool(), signer,
new CryptoPP::HexEncoder(new
CryptoPP::StringSink(sig))));
return sig;
}
static bool verify(const std::string& message, const std::string&
pub_key , const std::string& sig)
{
CryptoPP::StringSource pub_source(pub_key, true, new
CryptoPP::HexDecoder());
CryptoPP::RSASS<CryptoPP::PKCS1v15, CryptoPP::SHA>::Verifier
verifier(pub_source);
CryptoPP::StringSource sig_source(sig, true, new
CryptoPP::HexDecoder());
if (sig_source.MaxRetrievable() != verifier.SignatureLength())
return false;
CryptoPP::SecByteBlock signature(verifier.SignatureLength());
sig_source.Get(signature, signature.size());
CryptoPP::VerifierFilter *filter = new
CryptoPP::VerifierFilter(verifier);
filter->Put(signature, verifier.SignatureLength());
CryptoPP::StringSource(message, true, filter);
return filter->GetLastResult();
}
Any help would be appreciated
