# SM_CRYPTO 国家加密算法Dart版本
### Multiple encryption: 
1. sm2 (coding)
2. sm3
3. sm4

## Using
### SM3
```dart
String data = 'Hello! SM-CRYPTO @Greenking19';
String sm3Encrypt = SM3.encryptString(data);
print('👇 SM3 Encrypt Data:');
print(sm3Encrypt);
```
### SM4
```dart
String key = SM4.createHexKey(key: '1234567890987654');
String data = 'Hello! SM-CRYPTO @greenking19';
print('👇 ECB Encrypt Mode:');
String ebcEncryptData = SM4.encrypt(data: data, key: key);
print('🔒 EBC EncryptptData:\n $ebcEncryptData');
String ebcDecryptData = SM4.decrypt(data: ebcEncryptData, key: key);
print('🔑 EBC DecryptData:\n $ebcDecryptData');

print('👇 CBC Encrypt Mode:');
String iv = SM4.createHexKey(key: '1234567890987654');
String cbcEncryptData = SM4.encrypt(
  data: data,
  key: key,
  mode: SM4CryptoMode.CBC,
  iv: iv,
);
print('🔒 CBC EncryptptData:\n $cbcEncryptData');
String cbcDecryptData = SM4.decrypt(
  data: cbcEncryptData,
  key: key,
  mode: SM4CryptoMode.CBC,
  iv: iv,
);
print('🔑 CBC DecryptData:\n $cbcDecryptData');
```

### SmHelper
```dart
List<int> bytes = SmHelper.utf8ToBytes('@Greenking19');
String string = SmHelper.bytesToUtf8(bytes);
...
```
## Installing
With Dart:
```shell
    dat pub add sm_crypto
```
With Flutter:
```shell
    flutter pub add sm_crypto
```
This will add a line like this to your package's pubspec.yaml (and run an implicit dart pub get):
```yaml
dependencies:
  sm_crypto: ^1.0.3
```
## Import it

### Now in your Dart code, you can use:
```dart
import 'package:sm_crypto/sm_crypto.dart';
```
