generateKeyPair static method

Future<Map<String, String>> generateKeyPair({ String curve = secp256r1, })

Generates an ECC key pair for the specified curve

Implementation

  final generator = ECKeyGenerator();
  generator.init(rngParams);
  final pair = generator.generateKeyPair();

  final publicKey = pair.publicKey;

  // Convert to PEM format
