You need to use:
CryptoPP::StringSource decoder( prvkey, true, new
CryptoPP::HexDecoder);
temp1.AccessKey().Load( decoder );
Remember that information flows from left to right in a Crypto++
pipeline, like Unix pipes.

THIS WORKS. Any idea why? What is the negative interaction between the
HexDecoder and StringSource in the previous cases?
{ // BER Decode Private Key
CryptoPP::HexDecoder decoder;
decoder.Put( (byte*)prvkey.c_str(), prvkey.size() );
decoder.MessageEnd();
temp1.AccessKey().Load( decoder );
std::cout << "Dumping Public Key..." << std::endl;
DumpPublicKey( temp1 );
}
