Simple way to keep your SharedPreferences secure and safe.

Support migration legacy SharedPreferences to EncryptedSharedPreferences.

• Require minSdk 14.

How To Use

Installation

Add the following dependency to your build.gradle file:

dependencies {
    implementation 'dev.haenara:bricksharedpref:1.0.2'
    implementation "androidx.security:security-crypto:1.0.0-alpha02"
}

How to Migrate

When you encrypt existing plain-text data and get rid of legacy plain-text data, follow this method:

BrickSharedPreferences.migrateEncryptedSharedPreferences()

And all is done! 🎉

How to Access EncryptedSharedPreferences

After migration, use a BrickSharedPreferences instance instead of SharedPreferences.

All you have to do is changing codes like this:

Kotlin

// Only difference is adding "Brick" when you get SharedPreferences. 
mSharedPreferences = context.getBrickSharedPreferences(fileName, Context.MODE_PRIVATE)

Java

mSharedPreferences = new BrickSharedPreferences(context, fileName);

And all is done! 🎉

Sample Run

Sample app shows how BrickSharedPreferences works.

Hot it works

BrickSharedPreferences deletes the legacy SharedPreferences file, and copies and encrypts as a new file name start with "brick_".

After migration, just use a BrickSharedPreferences instance instead of SharedPreferences.
