Hi,
i am trying to sign a message using the code below.
void wxCryptopp::SignMessage( const std::string& PrivateKeyFileName,
const std::string& Message,
std::string& SignedMessage )
{
try
{
SignedMessage = "";
CryptoPP::FileSource privFile( PrivateKeyFileName.c_str(), true,
new CryptoPP::HexDecoder);
CryptoPP::RSASSA_PKCS1v15_SHA_Signer priv(privFile);
CryptoPP::AutoSeededRandomPool rng;
size_t length = priv.MaxSignatureLength();
wxMessageBox(wxString::Format("Signer Length : %d", length));
CryptoPP::StringSink* strSink = new CryptoPP::StringSink(
SignedMessage );
CryptoPP::HexEncoder* hexEnc = new CryptoPP::HexEncoder(strSink);
CryptoPP::SignerFilter* signer = new CryptoPP::SignerFilter( rng,
priv, hexEnc, true);
CryptoPP::StringSource s1(Message, true, signer);
}
catch (CryptoPP::Exception e)
{
wxMessageBox(e.GetWhat(), "Exception");
}
}
The app compiles ok but when i try to sign the message it fails at this
line:
- CryptoPP::StringSource s1(Message, true, signer);
There is no exception thrown.
I am using codeblocks and wxwidgets in winxp 32bit. I compiled the cryptopp
static library using mingw. Mingw is the compiler that i am using.
Thank you in advance.
