Demonstrates how to load an ECDSA public key from X and Y values using the LoadEcdsa method introduced in Chilkat v9.5.0.85.

Note

This example is intended for running within a Chilkat.Js embedded JavaScript engine. All Chilkat JavaScript examples require Chilkat v11.4.0 or greater.

var success = false;

// Note: This example requires Chilkat v9.5.0.85 or greater.

// We have the following x and y values in hex (for an EC point on the P-256 curve).
var x = "1ccbe91c075fc7f4f033bfa248db8fccd3565de94bbfb12f3c59ff46c271bf83";
var y = "ce4014c68811f9a21a1fdb2c0e6113e06db7ca93b7404e78dc7ccd5ca89a4ca9";

var pubkey = new CkPublicKey();
success = pubkey.LoadEcdsa("secp256r1",x,y);
if (success == false) {
    console.log(pubkey.LastErrorText);
    return;
}

console.log("Success.");
