An excellent application of "open source" camera firmware is encryption.

If you're a news photographer in a war zone, your life could depend upon it.


io_crypt is a module which automatically encrypts .CR2 and .JPG while you shoot them.

The original file content is never written to card, so there is no way to restore the image content by reading the raw sectors etc.

You can choose between different modes and security levels.
