使用pointycastle ()时"AES引擎未初始化“

import 'package:pointycastle/pointycastle.dart';

void main() {
  final key = KeyParameter([1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16]);
  final iv = IV([1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16]);

  final cipher = AESFastEngine();
  final params = ParametersWithIV(key, iv);
  cipher.init(true, params); // 初始化AES引擎

  // 在这里进行加密或解密操作
}

import 'package:pointycastle/pointycastle.dart';

void main() {
  final key = KeyParameter([1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16]);
  final iv = IV([1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16]);
  final plainText = 'Hello, World!';

  final cipher = AESFastEngine();
  final params = ParametersWithIV(key, iv);
  cipher.init(true, params); // 初始化AES引擎

  final plainData = plainText.codeUnits;
  final encryptedData = cipher.process(plainData);

  print('Encrypted: ${encryptedData}');
