EncryptedSharedPreferences

Kotlin |Java

class EncryptedSharedPreferences : SharedPreferences

kotlin.Any
↳	androidx.security.crypto.EncryptedSharedPreferences

An implementation of SharedPreferences that encrypts keys and values.

String masterKeyAlias = MasterKeys.getOrCreate(MasterKeys.AES256_GCM_SPEC);
 
   SharedPreferences sharedPreferences = EncryptedSharedPreferences.create(
       "secret_shared_prefs",
       masterKeyAlias,
       context,
       EncryptedSharedPreferences.PrefKeyEncryptionScheme.AES256_SIV,
       EncryptedSharedPreferences.PrefValueEncryptionScheme.AES256_GCM
   );
 
   // use the shared preferences and editor as you normally would
   SharedPreferences.Editor editor = sharedPreferences.edit();
