Got a response, thought I'd post it here for everyone else! privKey.Load(CryptoPP::StringStore((const byte*)data,(size_t)dataLen).Ref());
That's it, that's all! data is a char * containing the bytes of the key, and dataLen as you can probably guess is a const int with the length of data! Thanks Da Co!
