    var highScore1 by ecLongPref(1111111111L)
    var rate1 by ecFloatPref(0.5555f)
    var person1 by ecGsonPref(Person("g jafir", 21))
    var avatar21 by ecGsonPref(Avatar())

Advanced

If you want to custom your Cipher rules

Just implement CipherAdapter's encrypt and decrypt funs, like:

class SharedPrefCipherAdapter @Throws(Exception::class)
constructor(context: Context) : CipherAdapter {
    private val secretKey: SecretKey

    init {
        this.secretKey = AESUtil.generateKey(context)
    }

    override fun encrypt(raw: String): String {
        return AESUtil.execEncrypted(secretKey, raw)
    }

    override fun decrypt(encode: String): String {
        return AESUtil.execDecrypted(secretKey, encode)
    }
}

And more detail in the source code, you can see it
