Generate an ECDSA Key

Demonstrates how to generate an ECDSA key. Dart

import 'package:chilkat/chilkat.dart';

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

  // Create a Fortuna PRNG and seed it with system entropy.
  // This will be our source of random data for generating the ECC private key.
  final fortuna = CkPrng();

  // Chilkat also supports other curves, such as secp384r1, secp521r1, and secp256k1.
