See more ECC Examples

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

import { PublicKey } from '@chilkat/react-native'

function chilkatExample() {
  // 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).
  const x = '1ccbe91c075fc7f4f033bfa248db8fccd3565de94bbfb12f3c59ff46c271bf83';
  const y = 'ce4014c68811f9a21a1fdb2c0e6113e06db7ca93b7404e78dc7ccd5ca89a4ca9';

  const pubkey = new PublicKey();
  try {
    pubkey.loadEcdsa('secp256r1', x, y);
  } catch {
    console.log(pubkey.lastErrorText);
    return;
  }

  console.log('Success.');
