Google just gives me a bunch of classes schools offer for this. All other tutorials I've found just tell you how to find a message in the pictures.

Bumping for interest. Could be a onetime pad to remove a bunch of pixels or something? Iunno.

>>550874723
I've been screwing around in PS for a long time trying just about everything. There has to be some specific program I think.

shit, i mean to type Steganography

I presume you don't mean the image that's actually a zip folder. I don't know any other ways, but I can almost completely assure you that you won't be able to get to the other image with photoshop by changing hues, saturation etc.

I swear I saw a thread about this stuff before, but the fact that a message was hidden was way obvious...

Maybe open it as a .txt and observe the raw data?

>>550875745
We're talking about cryptography, pretty sure.

Look up Steganography tools? There seems to be a few listed on wikipedia.

Ok, seems like there are a ton of different methods, some of which require a password/key. So good luck, but I'd give up.

>>550874262
for finding stenographic images within images you need:
>either specialized stenographic software
>or an image, an editing software with different layer filters such as gimp and an image negative
>or extreme knowledge (there's around 259000 bytes of information in your picture, there are literally endless ways of hiding information in your picture)

>>550879716
disregard that, stupidity got a hold of me.

>>550879783
I have stenographic software. I know fuck all about it, but I have it.

So the image you've uploaded is a jpg image, which is vulnerable to compression. Makes things difficult.

I like VSL, It's nice software. It makes thing simpler.

If the message is larger than the image you're encoding it in, it prolly won't work.

>>550887304
Are you trying to encode or decode? If you're trying to encode, make sure the picture you're using to encode with is BIGGER than the message. If it's low-res you can still add to the resolution.

>>550887309
In the folder, there's a 'results' thing. Check it.

>>550887304
You need to have modules in the workspace.
>>550887309
When it says experiment finished it saves the file to a results folder inside of the program directory. You will probably have to change the file extension when you find the file though.

As long as you're using the same algorithms it should be fine. The tree has a specific algorithm but I don't think any of the modules included in VSL do it.

>>550893418
That case was a bit complicated. Let me direct you to this file

>>550889790
to start with.

First, open the jar.
On the right there are modules- open the 'tools' and the 'decoders' folders.

Drag 'input', 'LSB.D' and 'output' into the workplace. LSB.D is the algorithm to decode the LSB cipher.

Using right-click on 'Input', select 'connect' and click in LSB.D. Then right-click on LSB.D, select 'connect', and click 'output'.

Right click on "Input" and select "Select input". Choose the desired file to be decoded.

Press the green arrow when completed.

fuuuuu yep. got it! Why does it come out like that tho?

>>550894727
Just take a guess on the type of file and add the extension at the end of the name.

>>550895101
Yeah, there are two more questions. Are you trying to encode or decode? It looks like decode.
1) Are you sure the file you're trying to decode actually has a message?
2) Right click on LSB.D and select 'parameters'. What are startbit and endbit set to? If it's that picture of Velma they need to be set to 1 and 2, respectively. Otherwise set them both to 0, that's how it's been the rest of the thread.

And if it's this pic:
>>550890870
there is nothing on it.

>>550895216
Because the data is raw. It doesn't say 'hey lookit me i'm a .jpg' that's something you have to add on your own.

>>550895263
Alrigh, thanks dude! The one with velma is giving me trouble.

>>550895840
Because
>>550893215

Right click on the decode module and set startbit and endbit to 1 and 2, respectively. I wanted to see if it would make it look much different.
I should apologize for that, setting startbit and endbit to 0 was the norm for the ENTIRE thread.

I'm learning about the algorithms themselves rn and they're clever.

Right now I'm seeing how one can use the other filters. Like, the salt-and-pepper noise filter adds random black and white dots.

Try LSD. You will find alot of interesting stuff in images

I need to actually see how this works. Was able to hide a .rar in an image but that's about as far as I've gotten

>>550897493
Wait, do you need a video tutorial or not?

What happens is, in the color the least significant bit (the one that supplies the least amount of information) is changed for each pixel. This holds the information.

>>550897639
Just so we're on the same page. I want to see how to get hidden images from the images people are posting and how to create them.

>>550898303
It's a similar process to what you did to encode. Replace the LSB.E module with LSB.D, which decodes instead of encodes.

>>550897919
Got it, thanks /b/ro

If anyone wants to post encodings I'd love to decode them just for fun.

>>550897216
I know, the input was 4mb and the message was 2mb, the result was 19mb

so when you see a thread of a person holding a Cheese Pizza, thats a thing right or am i going to have to just try with every image?

I just used command prompt. Navigated to my directory and input this type of thing

copy /b imagename.jpg + archivename.rar newimage.jpg

>>550898646
The problem is they might not use the LSB encoding, or they might use LSB with some obscure startbit and endbit, or they might use F5 with a password, or they might use an entirely different algorithm altogether. Or they might literally be pictures of pizza.

Skimming the thread and can't find the answer so I might as well badger you guys again.

Figured out how to decode images, but I'm having trouble encoding them. Pic is what I have right now. So I selected an image for input, but how do I choose the image it is going to hide inside? I thought right clicking the display box would be the answer but the only options are "Connect, Show image, and "remove." And selecting output just asks you where you want to save it

GIMP is most definitely NOT a tool for doing this. At all. Ever.

>>550903521
You need to use the module LSB.E instead of LSB.D. The D is for Decode and the E is for Encode.
Once you do, right click the LSB.E module and select 'message' and choose the message. It doesn't have to be an image- it can be .txt or even an mp3.

>>550903772
Thanks a ton. Think I finally got it

>>550904140
Yup. Werks. Thanks

>>550904838
Post what you encoded? :D

Question. I can hide regular image files but for some reason I get this error when I try to put a .gif in either the input or the LSB.E I get this error

>>550906646
I don't think there's really an agreed-upon method to do .gif files.
You can encode a gif file certainly but you can't use it as the message

No problem! :D

>>550906826
Same error when gif is just in the input. Also figured out I cant put .mp3s as the message. Same error msg

>>550907415
It's possible the image you're embedding it in isn't big enough. That's why my MP3 was just 'Dun dun DADAAAA'

ok fuck it, gifs are difficult.
But this image has sound embedded.

My point was you can embed anything you want in pictures.

>>550906301
God dammit, I thought I had you at 77

>>550908257
Not working for me. Did you not use LSB, or did you have some weird bitstart/bitend?

>>550907963
Gif was 2.33 MB
Image I was trying to embed was 275 KB

It works fine for me.
What player/script are you using for playback?

Pic related, it also has sound. My voice, actually, specially for you <3

>>550908718
Seconding. Didn't work for me but then again I suck at this

>google 4chan media player
>install
>reload page
and then check my pics

This one also has sound

>>550883795
What's that LSB.E/LSB.D you're talking about?

All I know about steganography is how to hide a rar within a jpeg.

You guys getting it to work?

>>550909812
Werks now

>>550911924
Just to make sure you're not bluffing, tell me what you hear (in any one of them)

>>550911250
Hm
no
not working
*shrug*

>>550911692
Ok, test. Try to get the image within this one.

How do I open the image now?

Can someone explain what's going on in this thread? Far as i get it you're hiding images within other images, is this in a codey way or are you actually hiding stuff in plain sight? Sorry for being a newfag i guess.

>>550913737
others are hiding images within images
I'm hiding audio in them

see >>550909812 if you want the sound to work

>>550913737
In a coding way.

>>550911250
>Baby got back

>>550912243
Picture of ass has Big Butts song

>>550914120
>>550914201
okay okay
I was starting to think you were all retarded

Guys, this image>>550911250

won't work for me. What am I doing wrong?

http://snag.gy/UIMRa.jpg

>>550915180
That VSL stuff is for images dude.
That image has a song in it. audio..
install 4chan media player to hear it

>>550915449
Ok, thanks.

Can I embed other things than images using VSL though?

>>550915654
dunno I never messed around with that
back in the day people were hiding entire rar archives in pics, but that's not possible anymore
well, it is, but you can't upload them to 4chan anymore

Almost seems random as to which ones work and which ones I get an error for.

This werks >>550912505

This doesn't >>550878260

Didn't change anything. Just changed the input file

>>550915979
Oh well.

How can I embed any file in an image, other than an image?

>>550916084
>put anything you want in a rar file
>Place the image in c:. Then place the .rar file that you want to hide in the image in the same directory.

>Open up the command line by clicking, start, run, then type cmd, press enter.

>Navigate to the c:\ by typing, `*cd c:*.

>Type the following
>copy /b nameofimage.jpg + nameofrar.rar chooseanewname.jpg

that's it
now when you double click the image it will just open the image.
use winrar to open the rar.

but again, 4chan will detect it

>>550916639
I already know how to make a rarpeg, but how did this guy put music in his image?

>>550916639

ok, I tried to encode a quick message just to try.
pic is what I get.
txt works.
images work.
mp3, >>550889143 worked but >>550909812 and >>550911250 don't.
Weird.

>>550919220
same problem here, I think it's a java problem

>>550919220
lol with the extension it works great!
Still, can't fucking reproduce it with the jar application!

>>550919683
nice dude, thanks.

>>550919820
Also have been having this problem
