### Generally data is saved in this way in Android devices.

```xml

    

    

    

    

    en

    

    

    

    

    

    

    

    

    

    

    

```

### But when we use Encrypted SharedPreferences.

Add the required dependencies to your build.gradle file:

```groovy

dependencies {

    implementation("androidx.security:security-crypto:1.1.0-alpha06")

}

```

```kotlin

  fun init(context : Context) {

   

        val masterKeyAlias = MasterKey.Builder(context)

            .setKeyScheme(MasterKey.KeyScheme.AES256_GCM)

            .build()

        this.preferences = EncryptedSharedPreferences.create(

            context,

            SHARED_PREFERENCE_FILE_NAME,

            masterKeyAlias,

            EncryptedSharedPreferences.PrefKeyEncryptionScheme.AES256_SIV,

            EncryptedSharedPreferences.PrefValueEncryptionScheme.AES256_GCM

        )

    }

```
