flutter_keychain

A Flutter plugin for supporting secure storage of strings via Keychain and Keystore

If you have other types you want to store, you need to serialize to and from UTF-8 strings.

• Keychain is used for iOS
• AES encryption is used for Android. AES secret key is encrypted with RSA and RSA key is stored in KeyStore

Note KeyStore was introduced in Android 4.3 (API level 18). The plugin does not work on earlier versions.

Getting Started

import 'package:flutter_keychain/flutter_keychain.dart';
...

// Get value
var value = await FlutterKeychain.get(key: "key");

// Put value
await FlutterKeychain.put(key: "key", value: "value");

// Remove item
await FlutterKeychain.remove(key: "key");

// Clear the secure store
await FlutterKeychain.clear();

Configure Android version

In [project]/android/app/build.gradle set minSdkVersion to >= 18.

android {
    ...
    defaultConfig {
        ...
        minSdkVersion 18
        ...
    }
}
