Load an Ed25519 Private Key from Hex

See more Ed25519 Examples

Demonstrates how to load an Ed25519 private key from raw hex bytes.

Note: This example requires Chilkat v9.5.0.83 or greater.

.NET Core C#

bool success = false;

// This example assumes the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

Chilkat.PrivateKey privKey = new Chilkat.PrivateKey();

// We have the hexidecimal encoded bytes of the private key and public key:
string privKeyHex = "d4ee72dbf913584ad5b6d8f1f769f8ad3afe7c28cbf1d4fbe097a88f44755842";
string pubKeyHex = "19bf44096984cdfe8541bac167dc3b96c85086aa30b6b6cb0c5c38ad703166e1";

// Load these values into the Chilkat private key object:
success = privKey.LoadEd25519(privKeyHex,pubKeyHex);
if (success == false) {
    Debug.WriteLine(privKey.LastErrorText);
    return;
}

// ---------------------------------------------------------------
// We don't actually need the public key.  If we pass an empty string for the public key,
// Chilkat will automatically compute it.
Chilkat.PrivateKey privKey2 = new Chilkat.PrivateKey();
success = privKey2.LoadEd25519(privKeyHex,"");

// Let's get the public key to see that it computed the same value.
Chilkat.StringBuilder sbPubKeyHex = new Chilkat.StringBuilder();
privKeyHex = privKey2.GetRawHex(sbPubKeyHex);
Debug.WriteLine("computed public key = " + sbPubKeyHex.GetAsString());

// The output should be:
// computed public key = 19bf44096984cdfe8541bac167dc3b96c85086aa30b6b6cb0c5c38ad703166e1
