## Getting started
```yaml
dependencies:
sec: any
```
## Usage
```dart
import 'package:sec/sec.dart';
import 'package:convert/convert.dart';
```
```dart
final privateKey = BigInt.parse(
'c57304b3a53051600d7035fc593083810a8fa250e6a7a2803cf6a0f3c2750503',
radix: 16,
);
final publicKey = Secp256k1.createPublicKey(privateKey, true);
final pkHex = hex.encode(publicKey);
print('Public Key: $pkHex');
