Hidding your crap.exe into bmp, gif, jpg or png file. - Zilog80 - Sep 10, 2016

Oh C'mon boy!. Another HF's steganography tool. There are many around there.

You are right. But this is mine and want to share it.

Hope you like it and be useful to someone.

Is it possible to apply the same concept on videos??

Videos are just pictures played fast one after another.

Far as I understand in videos every once in a while there's a key frame and the later frames are encoded relatively to it, so if using the same concept wouldn't the small changes accumulate and show a difference?? or they wouldn't be that bad??

There are some eduactional papers out there explaining steganagraphy into videos.

You also 'hide' information in sound files (Wav, mp3, Ogg,...) using Fast Fourier Transforms 'hacks' and other techniques.

Anyway the sample I posted is a very basic stuff and the result will save into non-encoded-loss format like png or bmp.
