How to save the image on device as encrypted.

I'm using `DefaultCacheManager` to download the image on the device so that the next time it will be from the cache.
I want to cache these images as encrypted and when I get them back they should be decrypted.

How to achieve the same?

Start by reviewing DefaultCacheManager and the cache storage and retrieval flow to determine how encrypted image caching would fit. Establish the encryption and decryption requirements, then verify that cached images remain encrypted on the device and can still be read through the cache API.
