SM_CRYPTO 国家加密算法Dart版本

Multiple encryption:

1. sm2 (coding)
2. sm3
3. sm4

Using

SM3

String data = 'Hello! SM-CRYPTO @Greenking19';
String sm3Encrypt = SM3.encryptString(data);
print('👇 SM3 Encrypt Data:');
print(sm3Encrypt);

SM4

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

List<int> bytes = SmHelper.utf8ToBytes('@Greenking19');
String string = SmHelper.bytesToUtf8(bytes);

Installing

With Dart:

    dat pub add sm_crypto

With Flutter:

    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):

dependencies:
  sm_crypto: ^1.0.3

Import it

Now in your Dart code, you can use:

import 'package:sm_crypto/sm_crypto.dart';
