有人在 Flutter 上使用過 Rijndael 加密嗎？ 如何使用 Rijndael 進行加密？

Question

我正在使用加密 Flutter 包。 我寫了下面的代碼來加密數據。 但我找不到預期的結果。

  String encrypterAESdata({String? data}){ 
    final key = Key.fromUtf8(aesKey);
    final iv = IV.fromUtf8(aesKey);
    final encrypter = Encrypter(AES(key, mode: AESMode.cbc, padding: "PKCS7" ));
    final encrypted = encrypter.encrypt(data!, iv: iv);
    return encrypted.base64;
  }

Answer 1

我從來沒有發現圍繞pointcastle的“包裝”包很有用。 他們只是以添加“簡單性”的名義添加了混淆層。 直接使用底層包通常更容易。

import 'dart:convert';
import 'dart:typed_data';

import 'package:pointycastle/export.dart';

void main() {
  final k = 'Nec_uK_2@!6_CebD';
  final key = utf8.encode(k) as Uint8List;
  final iv = key;

  print(key);

  final cipher = PaddedBlockCipherImpl(
    PKCS7Padding(),
    CBCBlockCipher(AESEngine()),
  )..init(
      true,
      PaddedBlockCipherParameters(
        ParametersWithIV(KeyParameter(key), iv),
        null,
      ),
    );

  final data = utf8.encode(pt) as Uint8List;
  final ct = cipher.process(data);

  print(data.length);
  print(ct.length);
  print(base64.encode(ct));
}

final pt = '''{
  "remittanceNoPrefix": "IT",
  "adjustedDCAmount": 0,
  ...
  "cdExp": "",
  "cdSecCode": ""
}''';

Answer 2

十分簡單

import 'package:cryptography/cryptography.dart';

String s = "i want to encrypt this init";

String key = 'AA­èìýUn}a…ópŒ¹%J'yL4ßK,£½';

List<int> listint= utf8.encode(s);

Uint8List listUint= Uint8List.fromList(key.codeUnits);


AesGcm algorithm = AesGcm.with256bits();

SecretKey secretKey = await algorithm.newSecretKeyFromBytes(listUint);


    SecretBox secretBox = await algorithm.encrypt(
      listint,
      secretKey: secretKey,
    );

    print('Nonce: ${secretBox.nonce}');
    print('Ciphertext: ${secretBox.cipherText}');
    print('MAC: ${secretBox.mac.bytes}');


    Uint8List listEncryptedUint = secretBox.concatenation();
    print('this is the encrypted payload init: '+listEncryptedUint .toString());
