字节阵列到图像视图

Question

我正在尝试使用AES及其成功的工作来对图像进行加密

，但是一旦我获得了最终解密的字节阵列，我就无法设置为

  val bitmap = (imge.drawable as BitmapDrawable).bitmap
  val width = bitmap.width
  val height = bitmap.height
  val decryptedText: ByteArray = cipher.doFinal(bytes)

                
  val configBmp = Bitmap.Config.valueOf(bitmap.config.name)
  val bitmap_tmp = Bitmap.createBitmap(width, height, configBmp)
  val buffer = ByteBuffer.wrap(decryptedText)
  bitmap_tmp.copyPixelsFromBuffer(buffer)

  img.setImageBitmap(bitmap_tmp)

解密的文本，这是解密的字节阵列，一旦我在未加密的图像的帮助下进行了此操作，我就会得到宽度和高度以及使用它将字节阵列转回图像。

但是，我尝试在不使用以下代码的帮助下使用原始图像统计数据，例如高度和长度和位图。

 val decryptedText: ByteArray = cipher.doFinal(bytes)

 val ol = BitmapFactory.decodeByteArray(decryptedText, 0, decryptedText.size)
 img.setImageBitmap(ol)

但是，这不起作用，在日志猫中显示出来： -

D/skia: --- Failed to create image decoder with message 'unimplemented'

应用不会崩溃，但是我无法在图像视图中获得解密的图像，

如何将字节数组转换为位图，因此可以设置图像。

加密功能： -

   fun encryption(imageView: ImageView, name: String, uid: String) {
        val bitmap = (imge.drawable as BitmapDrawable).bitmap

        val size = bitmap.rowBytes * bitmap.height
        val byteBuffer: ByteBuffer = ByteBuffer.allocate(size)
        bitmap.copyPixelsToBuffer(byteBuffer)
        val byteArray = byteBuffer.array()

        Firebase.firestore.collection("profiles").document("YHMauLouORRtrYBV2h4dHJ5A0s72")
            .update("key", "$secretKey1")

        val cipher = Cipher.getInstance("AES")
        val keySpec = SecretKeySpec(secretKey1, "AES")
        cipher.init(Cipher.ENCRYPT_MODE, keySpec)
        val z = cipher.doFinal(byteArray)
        val file = File.createTempFile("$name", null)
        file.writeBytes(z)
        Log.d("first", "quick")
        val storageReference = FirebaseStorage.getInstance()
            .getReference("/image/0XhL4jD4XCemk38rcRkIEjJMgjh2/Aadhar/")
        storageReference.putFile(Uri.fromFile(file))
            .addOnSuccessListener {
                Toast.makeText(context, "Success", Toast.LENGTH_SHORT).show()
            }
    }

                val buffer = ByteBuffer.wrap(decryptedText)
                bitmap_tmp.copyPixelsFromBuffer(buffer)


                img.setImageBitmap(bitmap_tmp)
