Проблемы с отправкой RSA SecretKey из одного действия в другое

0 голосов
/ 04 августа 2020

Я пытаюсь сгенерировать ключ шифрования AES и использовать его для шифрования пароля в основном действии (действие входа в систему), а затем отправить тот же ключ ( SecretKey ) второму действию (подписать- up), чтобы использовать его и для шифрования. До сих пор я пытался «закодировать» ключ от SecretKey до String , чтобы иметь возможность отправить его как Intent Extra , затем закодируйте его обратно в SecretKey во втором действии. Вот код активности входа, который содержит кнопки ввода пароля и входа в систему и регистрации: 

//KEY GENERATION
        var logpass = login_password.text.toString()

        val plaintext: ByteArray = logpass.toByteArray()

        val keygen = KeyGenerator.getInstance("AES")
        keygen.init(256)

        val key: SecretKey = keygen.generateKey()
        val encodedKey = getEncoder().encodeToString(key.encoded)

//ENCRYPTION
signin_butt.setOnClickListener {
       
        val cipher = Cipher.getInstance("AES/CBC/PKCS5PADDING")
        cipher.init(Cipher.ENCRYPT_MODE, key)

        val ciphertext: ByteArray = cipher.doFinal(plaintext)
        val iv: ByteArray = cipher.iv

        val logpassencripted = String(ciphertext)
//other operations.........
}

//Sending key to sign up activity
signup_butt.setOnClickListener{
            var i=Intent(this,RegAct::class.java)
            intent.putExtra("AES key",encodedKey)
            startActivity(i)
        }

Вот код в активности регистрации, которая содержит ввод пароля и кнопку регистрации (reg_butt): 

//Fetching Key from Extra
val encodedKey2=intent.getStringExtra("AES key")

        val signpass= reg_password.text.toString()
        val plaintext: ByteArray = signpass.toByteArray()

//encoding key back to original format
        val decodedKey = getDecoder().decode(encodedKey2)
                // rebuild key using SecretKeySpec
        val originalKey = SecretKeySpec(decodedKey, 0, decodedKey.size, "AES")

//ENCRYPTION
reg_butt.setOnClickListener{
            val cipher = Cipher.getInstance("AES/CBC/PKCS5PADDING")
            cipher.init(Cipher.ENCRYPT_MODE, originalKey)
            val ciphertext: ByteArray = cipher.doFinal(plaintext)
            val iv: ByteArray = cipher.iv
            val logpassencripted = String(ciphertext)
//other operations.........
}

Нажатие кнопки регистрации во втором действии приводит к сбою приложения. Вот полный logcat: (я добавил System.out.println s для отображения значений переменных в журнале)
