For some reason, my code is not giving me proper pairs; it gives me a
private key that doesn't correspond to the public key I'm generating.
Everything is in hex.
Example:
private key:
e6d9f1845ccf7effe2e0a4d79a4adf59ab421e71127d16ff00c12b4a20d22d8d
x: ac43191cb357b72cbbcc26688ffefa9f5a1524ea5a19512bde902a3a823ca7ca
y: 21d409304f6bbc829e04793718929b0115e7daae6e6d4bc11a7fe405783a942e
compressed:
03ac43191cb357b72cbbcc26688ffefa9f5a1524ea5a19512bde902a3a823ca7ca
Brick o' code:
AutoSeededRandomPool prng;
ECDSA<ECP, SHA256>::PrivateKey privateKey;
ECDSA<ECP, SHA256>::PublicKey publicKey;
privateKey.Initialize( prng, CryptoPP::ASN1::secp256r1());
bool result = privateKey.Validate( prng, 3 );
cout << "valid: " << result << endl << endl;
const Integer& x1 = privateKey.GetPrivateExponent();
cout << "priv: " << std::hex << x1 << endl;
privateKey.MakePublicKey(publicKey);
result = publicKey.Validate( prng, 3 );
cout << "valid: " << result << endl << endl;
Integer qx = publicKey.GetPublicElement().x;
Integer qy = publicKey.GetPublicElement().y;
cout << "pub x: " << std::hex << qx << endl;
cout << "pub y: " << std::hex << qy << endl;
What've I done wrong?
