Get Base64 Public Key from Private Key

See more ECC Examples

Demonstrates how to get the public key in base64 format from a private key. C#

bool success = false;

// Load a private key from base64.
Chilkat.BinData bd = new Chilkat.BinData();
success = bd.AppendEncoded("MHQCA....n0Q==","base64");

Chilkat.PrivateKey privKey = new Chilkat.PrivateKey();
success = privKey.LoadAnyFormat(bd,"");
if (success == false) {
    Debug.WriteLine(privKey.LastErrorText);
    return;
}

Chilkat.PublicKey pubKey = new Chilkat.PublicKey();
privKey.ToPublicKey(pubKey);

string pubKeyBase64 = pubKey.GetEncoded(true,"base64");
Debug.WriteLine(pubKeyBase64);
