# Ed25519
Dart port of ed25519 from [Golang ed25519](https://github.com/golang/crypto/tree/master/ed25519)
[Pub package](https://pub.dev/packages/ed25519_edwards)
## Usage
```dart
import 'package:ed25519_edwards/ed25519_edwards.dart' as ed;
void signAndVerify() {
var keyPair = ed.generateKey();
var privateKey = keyPair.privateKey;
var publicKey = keyPair.publicKey;
var message = utf8.encode('test message');
var sig = ed.sign(privateKey, message as Uint8List);
var result = ed.verify(publicKey, message, sig);
assert(result == true);
var wrongMessage = utf8.encode('wrong message');
var wrongResult = ed.verify(publicKey, wrongMessage as Uint8List, sig);
assert(wrongResult == false);
}
```
