Encryption is important

pub points Pub

Features

• Simple to use yet powerful package to encypt shared preferences in android and UserDefaults in iOS.
• You have an option to by pass encryption just by passing a bool.
• Supports String, int, bool, double, map and List<String>.
• Uses advance AES-CBC-128 algorithm for encryption.
• Encrypts both key and value.
• Integration unit tests available here

Getting started

1. add dependency in pubspec.yaml file secure_shared_preferences:0.0.4
2. add import import 'package:secure_shared_preferences/secure_shared_preferences.dart';

Usage

1. To save string data type to secure storage.

    var pref = await SecureSharedPref.getInstance();
    pref.putString("Key", "This is data I want to save to local storage", isEncrypted : true);

1. To get string data type to secure storage.

    var pref = await SecureSharedPref.getInstance();
    pref.getString("Key", isEncrypted : true);

Usage

1. Save :

    var pref = await SecureSharedPref.getInstance();
    await pref.putString("StringEncrypted", "This is my first string test",isEncrypted: true);
    await pref.putInt("key", 100, isEncrypted: true);
    await pref.putMap("mapKey", {"Hello":true}, isEncrypted: true);
    await pref.putDouble("doubleKey", 20.32, isEncrypted: true);
    await pref.putBool("boolKey", true,isEncrypted:  true);
    await pref.putStringList("listKey", ["S","K"], isEncrypted: true);

First parameter is the 'key' Second parameter is the value Third parameter is whether you want to encrypt this key/value or not.

2. Fetch :

    var pref = await SecureSharedPref.getInstance();
    await pref.getString("StringEncrypted", isEncrypted: true);
    await pref.getInt("key", isEncrypted: true);
    await pref.getMap("mapKey", isEncrypted: true);
    await pref.getDouble("doubleKey", isEncrypted: true);
    await pref.getBool("boolKey",isEncrypted: true);
    await pref.getStringList("listKey", isEncrypted: true);

First parameter is the 'key' Second parameter is whether you have encrypted this key/value or not.
