val keyGenParameterSpec = MasterKeys.AES256_GCM_SPEC The following code can be placed where you plan to create your EncryptedSharedPreferences instance. The security library provides us with an easy way to do this.

With the dependency added, the next step is to create an encryption master key and store it in the Android KeyStore. This means that while the functionality is stable, parts of the API may be changed or removed in future versions. It’s important to note that this library is currently in the alpha phase. Be sure to check the library’s releases page to see if a newer version is available. This is the latest version as of this writing.

implementation 'curity:security-crypto:1.0.0-alpha02' To get started with the AndroidX Security library, add the following dependency to your module-level adle file. Thankfully, the AndroidX Security library was recently added and makes storing encrypted shared preferences data simple and easy for apps with a min-sdk of 23+. Another option is to use a third-party library, which means that we need to spend time finding and vetting one. Unfortunately, that can be pretty complicated and involve a lot of setup. One option is to write our own encryption wrapper around SharedPreferences using the Android KeyStore. We should encrypt sensitive data to keep it from prying eyes. When working with sensitive data, however, it’s important to consider that SharedPreferences stores data as plain text. The Android framework provides us with SharedPreferences, which is a great way to store a small amount of key-value data.

Finally, we can use the factory method created omJson() to access the value of each instance variable.Encrypting Shared Preferences with the AndroidX Security Library The jsonDecode() method will parse the String and return it as a Map. Then to retrieve, we can use getString() which will return a value of type String? which we pass to jsonDecode(). Then using the jsonEncode() method we can convert the object to a JSON string and store it. Here we first create a storingPayment() method and inside the method create an instance of Payment class. So first to add it you need to navigate to the pubspec.yaml file, and write the following:Ĭlass _MyHomePageState extends State Shared preferences will store data locally on the device, so for example if you want to use some data in a different page then you can use the Shared Preferences to store and retrieve that data.
