Не удается загрузить изображение из CipherInputStream

Glide Версия: 4.8.0

Библиотеки интеграции: Нет

Версия устройства / Android: OnePlus 3, Android 9.0

Сведения о выпуске / Действия по воспроизведению / Фон варианта использованияЯ использую Glide для загрузки зашифрованных изображений из локального хранилища.Я зашифровал изображения, используя AES-128.Моим первым подходом было декодирование изображения и использование получившегося массива ByteArray для загрузки изображения с использованием Glide.Это хорошо работает для маленьких изображений, но выдает ошибку OOM для больших изображений и когда я пытаюсь загрузить миниатюры видео.Очевидно, этот подход был очень наивным.Затем я создал собственный ModelLoader для загрузки изображения с использованием потока, но они не загружаются.Похоже, проблема в пути декодирования.Я новичок в Glide, и некоторая помощь будет очень ценной.
