PNGDrive – The easiest path to plausible deniability
PNGDrive is a free file system for Linux licensed under the GPL 3. It is as a steganographic file system that allows users to access file systems hidden within PNG images.Using this tool you can access any PNG image as if it were a file-system, meaning you can copy files into it, edit files from it, remove, etc… and once you’ve finished its just a picture.
