Can you tell me details? Change which file?

from stegoveritas.

So i just switched it over. It's the fact that I was utilizing the GNU file command, which won't be installed by default on Windows machines. I haven't had a chance to test this, so let me know how it works for you.

You'll need to pip install python-magic

The changes are in the "noFileCommand" branch for now (https://github.com/Owlz/stegoVeritas/tree/noFileCommand).

windows7 x64 python 3.5.2

if I just install python-magic

magic.MagicException: b'could not find any magic files!'

then I change the imageLSB.py file

changed code

def testOutput(b,args):
import magic
m = magic.Magic(magic_file="C:\GnuWin32\share\misc")
m2 = m.from_buffer(b,mime=True)
if m2 != 'application/octet-stream':
m2 = magic.from_buffer(b,mime=False)
print("Found something worth keeping!\n{0}".format(m))
# Save it to disk
with open(os.path.join(args.outDir,str(time.time())), "wb") as f:
f.write(b)

result

**I guess that the magic.from_buffer have some problem， I know a little about magic.from_buffer，maybe you have some solutions **

from stegoveritas.

Hmm.. So looks like this library (and most others I've seen) relies on libmagic. That said, one thing you probably want to do is provide the fill magic file path instead of the directory:

 m = magic.Magic(magic_file="C:\GnuWin32\share\misc\magic")

Another issue I'm seeing on the windows side is getting the proper DLLs (and right architecture for them) in the correct places. Not sure what a good answer is for now as it seems the Windows solutions for libmagic aren't the greatest.

I'll keep this issue open as a reminder.

from stegoveritas.

I should say, my guess is that the DLLs could be packaged with python and a smart setup script created for them so that libmagic will work out of the box. However, that would involve updating their rep/creating my own fork of it, as well as shipping with DLLs. Not a horrible thing, but not really what one wants to do with python either.

This issue ticket is from well before the refactor. Not really a thing anymore.
