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
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
