Encryption while disk caching

Question

So what I to achieve is to apply encryption while caching images on disk. I have decided to go with Universal Image Loader, I understand I will have to add an custom disk caching implementation of my own but I don't know where to start with.

How can I achieve this, encryption while writing byte stream in file and decryption while getting the stream only from file.

Any kind of help would be deeply appreciated :)

Thanks for not replying :P

But I did eventually end up solving it. And here is what I did, maybe It will help anyone else. All I had to was to create a custom disk cache and custom downloader. In custom disk caching class, in the method where UIL write byte stream to file, I encrypted the byte stream. and In custom downloader, I override the method where it take byte stream from file and decrypted it.
