I've seen - http://stegosploit.info/ - it's adding certain data.
I'm not that sophisticated, I just want to have in an image file:
- file header
- encrypted data
- the image does not have to be real (could be the visual representation of the encrypted data)
Is there a file format that would allow such thing? (I understand some file formats might be difficult to work with).
Is there a website allowing me to submit the base image and encrypted data?
The goal here is to distribute encrypted data across a large number of image files on image hosting websites. (first checking if the sites use lossless compression).
