# Elliptic curve cryptography (ECC) in Dart

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

[![Build Status](https://travis-ci.com/primes-network/eosdart_ecc.svg?branch=master)](https://travis-ci.com/primes-network/eosdart_ecc)

## Usage

A simple usage example:

```dart

import 'package:eosdart_ecc/eosdart_ecc.dart';

main() {

  // Construct the EOS private key from string

  EOSPrivateKey privateKey = EOSPrivateKey.fromString(

      '5KQwrPbwdL6PhXujxW37FSSQZ1JiwsST4cqQzDeyXtP79zkvFD3');

  // Get the related EOS public key

  EOSPublicKey publicKey = privateKey.toEOSPublicKey();

  // Print the EOS public key

  print(publicKey.toString());

  // Going to sign the data

  String data = 'data';

  // Sign

  EOSSignature signature = privateKey.signString(data);

  // Print the EOS signature

  print(signature.toString());

  // Verify the data using the signature

  signature.verify(data, publicKey);

}

```
