Hi,
I'm trying to use Crypto++ with boost::python. My code seems to build OK,
but when I try to import it into Python, I receive this error:
ImportError: nf_decrypt.so: undefined symbol:
_ZN8CryptoPP21SimpleKeyingInterface6SetKeyEPKhmRKNS_14NameValuePairsE
Here is the cpp source code file:
#include
#include
#include
std::string nf_decrypt( const std::string& estring )
{
std::string hex_pk = "00000000000000000000000000000000";
std::string hex_iv = "00000000000000000000000000000000";
std::string pk;
std::string iv;
std::string cipher_text;
std::string plain_text;
CryptoPP::StringSource ( hex_pk.c_str(), true, new
CryptoPP::HexDecoder( new CryptoPP::StringSink(pk) ) );
CryptoPP::StringSource ( hex_iv.c_str(), true, new
CryptoPP::HexDecoder( new CryptoPP::StringSink(iv) ) );
CryptoPP::StringSource ( estring.c_str(), true, new
CryptoPP::StringSink(cipher_text) );
CryptoPP::AES::Decryption aesDecryption( (byte*)pk.c_str(),
CryptoPP::AES::DEFAULT_KEYLENGTH );
CryptoPP::CBC_Mode_ExternalCipher::Decryption cbcDecryption(
aesDecryption, (byte*)iv.c_str() );
CryptoPP::StringSource( cipher_text, true, new
CryptoPP::StreamTransformationFilter( cbcDecryption, new
CryptoPP::StringSink(plain_text)));
return plain_text;
}
// python wrapper
#include
BOOST_PYTHON_MODULE(nf_decrypt)
{
boost::python::def("nf_decrypt", nf_decrypt,
boost::python::args("string_to_decrypt"), "nf_decrypt docstring");
}
Has anyone built boost python extensions from Crypto++ code? I may try
doing the same thing with Botan if Crypto++ in general is problematic. I
can send my Jamroot file if that would be helpful. Thanks for any advice.
