Elliptic curve cryptography (ECC) in Dart

Elliptic curve cryptography lib for Steem based blockchain in Dart lang.

Usage

A simple usage example:

import 'package:steemdart_ecc/steemdart_ecc.dart';

main() {
  // Construct the Steem private key from string
  SteemPrivateKey privateKey = SteemPrivateKey.fromString(
      '5KQwrPbwdL6PhXujxW37FSSQZ1JiwsST4cqQzDeyXtP79zkvFD3');

  // Get the related Steem public key
  SteemPublicKey publicKey = privateKey.toSteemPublicKey();
  // Print the Steem public key
  print(publicKey.toString());

  // Going to sign the data
  String data = 'data';

  // Sign
  SteemSignature signature = privateKey.signString(data);
  // Print the Steem signature
  print(signature.toString());

  // Verify the data using the signature
  signature.verify(data, publicKey);
}
