How to encrypt password while saving in database in Flutter-SQLite-Dart application?-CodePudding

I'm developing a mobile application using Flutter, Dart and SQLite. It is just a Login page validation kind of project where I need to encrypt the password and user's personal details while inserting in the database. At least I want the password to be encrypted. How is it possible to achieve this?

CodePudding user response：

You can use encrypt plugin to encrypt strings.

you can do like this for Advanced Encryption Standard (AES):

      final plainText = 'YOUR_PASSWORD';
      final key = Key.fromUtf8('my 32 length key................');
      final iv = IV.fromLength(16);
    
      final encrypter = Encrypter(AES(key));
    
      final encrypted = encrypter.encrypt(plainText, iv: iv);
      final decrypted = encrypter.decrypt(encrypted, iv: iv);
    
      print(decrypted); // YOUR_PASSWORD
      print(encrypted.base64);// YOUR_ENCRYPTED_STRING

I've used cryptographic hashing functions for Dart and it works fine for me.

The below code is what I used to encrypt the password.

import 'package:crypto/crypto.dart';
import 'dart:convert'; // for the utf8.encode method

void main() {
  var bytes = utf8.encode("password"); // data being hashed

  var digest = sha256.convert(bytes);

  print("Digest as bytes: ${digest.bytes}");
  print("Digest as hex string: $digest");
}
