Dear Puppians,

Here is a little app I threw together that makes use of outguess (a CLI-based steg program) to create a jpg file containing embedded/hidden files.

Please read the help and the about to understand how this program functions. And note that the container or vessel image should be some 15x larger than the proposed inserted file. I know, I can improve the logic in a few places and will do so in the next release.

Have fun.

With kind regards,
vovchik

PS. Please let me know what works and what doesn't, and what should/might be changed.

PPS. I forgot to mention it before, but the Einstein image (/usr/local/Psteg/img/psget-overview.jpg) contains a hidden file and message. The password is "password" without the quotes.

I was writing a generic (size independent) steg-ish program here:
http://www.murga-linux.com/puppy/viewtopic.php?t=72807

and this thread came up b/c I was naming it psteg

while I was doing my research I also compiled jsteg (converts ppm/gif to a jpeg with an encoded file) it has similar file size limits but is quite small so I will post it in case it is useful (it wasn't to me)

anyhow, my version is independent of file size if you want to add it to your gui ... otherwise I can name it steg-osaurus

Dear technosaurus,

I will certainly have a look. In any case, the gui needs revision because of the old gtkdialog method of closing child windows, so I have every reason to muck about with the code and include jsteg. Thanks...

With kind regards,
vovchik

sorry, that didn't come out right - jsteg is still size dependent (but smallish) ... which is why i started the new project.... everything had file size limitations or was bulky or had some obscene dependency, so I am just using already included tools instead (bcrypt, cat and tail with a gtkdialog4 frontend)
