The code that trying to encrypt the data: (IStorageRepository is basicly a SharedPrefferences) class TwoWayAES extends ITwoWayEncryption {
static const AESMode _mode = AESMode.ofb64Gctr;
// secure storage
final IStorageRepository secureStorage;
const TwoWayAES({required this.secureStorage});
@override
Future<String> encrypt(String plainText) async {
final key = Key.fromUtf8(EncryptionEnv.privateKey);
final encrypter = Encrypter(AES(key, mode: _mode));
final encrypted = encrypter.encrypt(plainText, iv: await getIv);
return encrypted.base64;
}
@override
Future<String> decrypt(String base64) async {
final key = Key.fromUtf8(EncryptionEnv.privateKey);
final encrypter = Encrypter(AES(key, mode: _mode));
var encrypted = Encrypted.fromBase64(base64);
final decrypted = encrypter.decrypt(encrypted, iv: await getIv);
return decrypted;
}
@override
Future<bool> isValid(String encryptedText, String test) async {
final key = Key.fromUtf8(EncryptionEnv.privateKey);
final encrypter = Encrypter(AES(key, mode: _mode));
final encryptedTest = encrypter.encrypt(test, iv: await getIv);
var result = encryptedText.compareTo(encryptedTest.base64) == 0;
return result;
}
Future<IV> get getIv async {
var iv = await secureStorage.read(EncryptionEnv.publicKey);
if (iv == null) {
var newIv = IV.fromSecureRandom(16);
await secureStorage.write(EncryptionEnv.publicKey, newIv.base64);
return newIv;
} else {
return IV.fromBase64(iv);
}
}
}Note: It seems like problem is with the Also oppened an issue at encryption repository to direct here. |

Hi hsynksahin Did you find solution? I face same issue when upgrade from 3.13.7 to 3.24.3. Using pointycastle (3.7.4) / encrypt (5.0.3) code Thanks. |
|
Unfortunately I did not! But staying in specific version does it. Just initialize a seperate package with seperate pubspec.yaml so the encrypt: 5.0.3 # last working: 5.0.3
pointycastle: 3.9.1 # last working: 3.9.1And Im using Hope this will work for you too. |

After updating Flutter version pointy castle started to give me errors with the same code.
I am using the
encryptpackage which uses this package. The same encryption code was working a few days ago, I have upgraded the flutter now its gives me'package:pointycastle/src/ufixnum.dart': Failed assertion: line 198 pos 10: '(x >= 0) && (x <= _MASK_32)': is not true.error when I try to encrypt something with it. Can anyone explain why this could be happen?When I downgraded the flutter to 3.19.0 and there is no problem, but after upgrading to 3.19.1 the exception occurs.
