YASA (Yet Another Steganography Application)

(1/2) > >>

hollowlife1987:
YASA is a small learning project made in C# using the .Net framework 2.0
YASA will take an source image in bmp, png or jpg format and hide any type of data inside of it and save as png

EDIT:
Tested YASA under Ubuntu 7.04 using Mono and it works perfectly fine. :)
If a mac user with an intel and/or ppc cpu could please test using mono it would be greatly appreciated.

Ubuntu 7.04 running YASA

This is pretty cool.

How well would this work with a highly compressed jpg file that has the right amount of pixels to hide the desired file?

Would this result in an image that would have a much larger file size than the original image + the hidden file?

hollowlife1987:
Yeah, converting from jpg to png will increase the file size quite a bit actually.
But if you take a regular png and add the data to it it shouldn't change the file size much if at all.

Deozaan:
Neat! Here's one with hidden information inside!

Veign:
That's kinda cool.  I wrote on that would let you hide simple phrases inside of an Image file but think your method of hiding a file is a much better idea.
