[steghide-devel] Problem mit steghide "extract" ...

[Martin K. <in...@ai...>]

Hallo an alle -

  **steghide v0.5.1 (W32) auf Vista Business SP2 32-bit **

Hatte heute beim Extrahieren einer Datei aus einem JPEG Bild
https://julianoliver.com/output/number-was-the-substance-of-all-things
folgenden Fehler:

-code-

I've had 2 private replies, only one was an offer of help.

I'll wait a few more days, but it really looks like this is a dead project.

[steghide-devel] steghide - still active or dead?

[Colin T. <co...@tu...>]

I've been peripherally interested in steganography for a long time.

Recently as a Debian Developer I noticed that the Debian package for
steghide has been orphaned (which means it now has no maintainer).

Before deciding to adopt the Debian package I wanted to check to see if
the upstream project was still alive.

I posted a message to "shetzl" the SF project owner but have had no
response.

This mailing list looks very dead too.

Is anyone actually still interested in steghide?

regards, Colin

[steghide-devel] steghide on centos 7?

[Penrose K. <pen...@gm...>]

Has anyone buitl steghide on CentOS 7?

So far I've:
1) Setup build environment
     yum install epel-release
     yum install libmcrypt-devel -y
     yum install libmhash-devel -y

2) Download steghide from http://steghide.sourceforge.net and extracted it.

3) Ran configure

4) Attempted to compile.  This is where I get a bunch of template errors.

Has anyone already worked through this?

Thanks,

Penny.

Re: [steghide-devel] 0.5.1 can't make steghide in x86_64 CentOs ? AudioDataImpl requires 'template<>' syntax

[Bruno R. <bru...@ho...>]

SOLVED !

Steps to recompile on CentOS (Linux 3.10.0-229.4.2.el7.x86_64) :
>> Ensure MHash zlib libtool and GCC C++ compiler are installed (with their -devel headers)

>> Insert in src/Graph.cc (to avoid an undefined ULONG_MAX error msg)
#include "limits.h"

>> Prefix every Const in src/AuSampleValues.cc and src/AuData.h by 
template<>

>> Add a -fpermissive compilation flag when making MHashPP.o or modify MHashPP.cc (to avoid invalid conversion error like below)
MHashPP.cc:123:38: error: invalid conversion from ‘uint8_t* {aka unsigned char*}’ to ‘char*’ [-fpermissive]
  char *name = mhash_get_hash_name (id) ;

Hi,

I tried to build steghide for my CentOS VM (x86_64) :
-Success from the "./configure" step
-Errors for the "make" step. See below for an example
In file included from AuFile.cc:26:0:

 inline BYTE AuMuLawAudioData::readValue (BinaryIO* io) const { return (io->read8()) ; }

As I am not a C++ dev, I can try anything you may ask me...but I don't think I can fix that by myself...

Re: [steghide-devel] Steghide running on debian 3.2.48 w/ gcc 4.4.5

[Rællic S. <dir...@ra...>]

This follows up on my previous message: http://sourceforge.net/p/steghide/mailman/message/32489443/

In case anyone is wondering, here is what we're doing with steghide: https://www.raellic.com/prism/

Thanks for developing such a cool program.  I hope it gets updated some day.

[steghide-devel] Steghide running on debian 3.2.48 w/ gcc 4.4.5

[Rællic S. <dir...@ra...>]

I had significant difficulty getting steghide to compile, but eventually it seems to have worked.  The application passes its self-tests, but I defer to actual programmers for their opinions on whether this is a solution.

First, I had the problems shown here and I fixed them using the instructions on those bug pages:

http://sourceforge.net/p/steghide/mailman/message/575573/
Error: "too few template-parameter-lists"
Solution: add "template <>" before "const" to 8 lines of src/AuData.h starting at line 24

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=455394
Error: "'ULONG_MAX' was not declared in this scope"
Solution: add "#define ULONG_MAX 4294967295" to src/Graph.h

Then the following problems surfaced, and proposed solutions are indicated:

Error: "MHashPP.cc:123: error: invalid conversion from 'uint8_t*' to 'char*'"
Solution:
Download and extract the latest mhash (0.9.9.9 as of this writing).
Edit mhash-0.9.9.9/include/mutils/mutils.h at line 51 and line 82.
On line 51, change "#define mutils_word8 uint8_t" to "#define mutils_word8 char"
On line 82, change "typedef unsigned char mutils_word8;" to "typedef char mutils_word8;"
Rebuild and install mhash.

Error: "MHashKeyGen.cc:60: error: invalid conversion from 'unsigned char' to 'char'"
Solution: edit src/MHashKeyGen.cc by deleting "unsigned" from line 60 so that mhash_keygen_ext takes a char instead of an unsigned char.

At that point steghide compiled, although I got a lot of warnings for "deprecated conversion from string constant to 'char.'"

Apparently I did not have libtool installed, so I installed it and was then able to install steghide.

I've provided my full output here in case anyone wants to look at it (sorry for the length; I have no clue): https://www.raellic.com/files/steghide_install_2014-06-21.txt

I tested steghide by embedding "Hello World!" in a small jpeg and extracting it, and it seemed to work.  So I welcome comments from people who actually know what they are doing.

Thanks,

Andrew Watters

[steghide-devel] Re: Colour loss when using steghide on jpeg

[ioannis l. <lat...@gm...>]

I tested another steganography software and it produces the same results,
so I am guessing there is some third party library that is causing the problem, 
although I am not sure which one it is yet.

[steghide-devel] Colour loss when using steghide on jpeg

[ioannis l. <lat...@gm...>]

I am using the following command: 

steghide embed -v -f -ef embeded.txt -cf desert.jpg -sf desertWithSteg.jpg

Output:

Enter passphrase: 
Re-Enter passphrase: 
reading secret file "embeded.txt"... done

writing stego file "desertWithSteg.jpg"... done


On the resulting image, desertWithSteg.jpg, there is significant colour loss. The colours are much more dim
and washed out. I couldn’t find any suggestions on the cause of this problem 

The two images are available on the following link. Any suggestions as to what might be causing this?
I am  using OSX 10.9.1 with steghide 0.5.1 installed via macports.

Hello Everyone,

I'm a developer who loves StegHide. I'm thinking about writing a GUI
for it but I don't want to duplicate effort. I've done some Google
searches and found StegGUI but it just seems to be informtion about
StegHide.

Has anyone actually written a GUI for the program? If not, I'd like to
do it.

Thanks,

[steghide-devel] a bug in the cygwin steghide build

[Anonymous A. <ono...@ma...>]

The build of steghide 0.5.1 for windows (cygwin), available at http://steghide.sourceforge.net/download.php,
has a problem with passphrases containing apostrophes.
Test case:
Let's say we have an image, test.jpg, and a batch file test.bat containing the following two lines:
steghide embed -cf test.jpg -ef test.bat -p a'a -f
steghide extract -sf test.jpg -xf - -p a'a

(Notice the absence of quotes around passphrases (it's legal in windows) and an extra option after the first passphrase)

And if we run test.bat:
C:\>test.bat

C:\>steghide embed -cf test.jpg -ef test.bat -p a'a -f
embedding "test.bat" in "test.jpg"... done

C:\>steghide extract -sf test.jpg -xf - -p a'a
steghide: could not extract any data with that passphrase!


Oops! Steghide cannot extract the data embedded.
I've built steghide using mingw, and the resulting executable appears to not have this problem. As for the native Linux build, no such problems exist, too.

[steghide-devel] Question: "the cover file is too short to embed the data"

[kr a. <k_...@fa...>]

Can somebody give me a rule of thumb as to how much bigger a cover file
needs to be than an embed file in order to hide it? Or if size isn't the
only factor, what are the others that will affect the maximum size file
that can be embedded into a cover file. I didn't know where else to ask
this, so I'm asking here. I appreciate any information that you can give
me.

[steghide-devel] Cracking a passphrase

[Tommy E. <t.e...@gm...>]

Okay I got a major favor to ask the mad scientists running this wonderful
operation.  Let me give just a small briefing first.

I am a 3rd year student graduating NST from a jr college.  I am in a Ethical
Hacking class and the teacher has derived a game of CTF.  I am at the point
where I have found five picture that have been embedded using Steghide.  I
need to find a way to crack these passphrases.  The first person to find the
flag gets an 'A' in the class.  As you can see I would be greatly
appreciative if I could get a little nudge in the correct direction.

As of now I have found nothing to reveal the passphrase of a picture
embedded using steghide.

Thanks in advance,
Tommy

Seems this was correct, but these other header files still have errors.

Maybe the steghide developers, more familiar with the code, have a  
more informed context to share.

Any more ideas?



This issue seems to be the same as Buckley Collum wrote about on  
steghide-devel on 10 July 2005.

http://sourceforge.net/mailarchive/forum.php? 
thread_id=7483334&forum_id=6018

Perhaps it's part of the same GCC 4.x problem?  Perhaps it's  
something else unique to OSX / Darwin?

Quite right; thanks again.  The issue seems to be patching the  
steghide code to conform to GCC 4.x, of which Apple includes GCC 4.01  
with Xcode.  The Gentoo portage maintainers include a patch precisely  
for this at the location you mentioned:
http://rsync1.it.gentoo.org/gentoo-portage/app-crypt/steghide/files/ 
steghide-0.5.1-gcc4.patch

Reading
http://darwinports.opendarwin.org/docs/ch03s03.html
http://darwinports.opendarwin.org/docs/ch04s07.html

I created a files/ directory in the development port directory for  
steghide, and placed the aforementioned patchfile inside.
I then added the following line to the Portfile:
patchfiles        steghide-0.5.1-gcc4.patch

The relevant snippet of the build process below reflects this, but  
you can read that it fails basically because the patch isn't prepared  
in the Darwinports style, it seems to me.  From the documentation,  
I'm not clear on how to covert the patch; namely what the  
requirements are on the Darwinports side of things.  (Generally,  
breaking out the patch into .diff files for each source file to be  
patched, correct?  ...as -p0 rather than -p1 is used by the patch tool.)

Re: [steghide-devel] creating steghide portfile, won't build

[zuzu (sean) <sea...@gm...>]

Thanks for your help so far. :)

Technically, libjpeg is optional (if you never want to encapsulate  
your data with JPEG), what's causing the level one error is a failure  
with libmhash.

The three checks which returned a no value include:

checking for mhash_init in -lmhash... no
checking for mcrypt_generic in -lmcrypt... no
checking for jpeg_read_coefficients in -ljpeg... no


With the Portfile changes you recommended, the configure stage  
completes (the no values change to yes).

configure.env     CPPFLAGS=-I${prefix}/include \
                   CFLAGS=-I${prefix}/include \
                   LDFLAGS=-L${prefix}/lib


But now the actual build fails.  Errors with SampleValue.h, AuData.h,  
and AudioData.h, in trying to build AuFile.o


checking for /dev/urandom... yes
checking for /dev/random... yes

[steghide-devel] Ruslan Kovalenko (Ukrain->Crimea)

Hi.
Sorry for my bad english.
Can you tell which functions do you use from library jpe-6b (www.ijg.org)
to hide message in to jpeg files ?
And what technics ?
Do you use lsb with DCT coefficient, or you use some other bytes ?

Best regards, Ruslan.
