Encryption Integration

Hello,

i started using CKFinder and trying to find a way to encrypt the files while uploading and while reading them in CKFinder Browser. The upload works fine, but unfortunately i can't find a way to decrypt them while loading the image...

Are the files loaded like normal images "http://example.com/images/test.png" or is the source passed to the client with a script?
Because i want to rewrite it to "http://example.com/image.php?file=test.png&folder=images", so that i can simply load the file decrypt it and return a image header.

But i cant find the line to manipulate it.

Can someone help?

PS: sry for my bad english
