Steganography tools

[Happy Chappies]

Hi all,

I've just entered the world of steganography (kicking and screaming I might add!) due to a few fiendish puzzle caches down this way which have peaked my interest.... (Damn curiosity getting ahead of my general capability and IQ levels!)

So I'm wondering what tools people have used out there in terms of decoding steganography puzzles... I've been playing with lots of free downloads and online tools but none are helping me do what I want to. (Which of course may mean there's no 'easy way' to decode and I'm wasting my time in hopeful vain)

Cheers

Eddie

There are many and varied.
Generally the puzzle will indicate which one and what key (thingy) you need.
Which ones?*

*Not that I'm going to give an answer, just sticky beaking.

Let's just say that a certain Mr B. Bear is causing me the grief right now.... Not sure if it's the same approach in the few I'm looking at (The Diabolical series and Stego (dash) cache) but I'm intrigued by the lot of them....

Right.
Done them both.
Easy, peasy
Actually one is easy, the other I'm not sure is that easy as I think there is a logic leap you need to make (or be persistent).

When I first discovered steganography, I had the owner help me out - I'd never even heard of it before! (Think learning about it when you'd found <100 caches. Still newbie right!)
And then I found out about BB cache in the middle of the bay, and just flat out asked him what the software he used to crypt it as I didn't want to download every possible program available on the net and risk my PC. I did however try a few online things firstly....

I've found that owners are not THAT mean, if at least you've shown some innitative to solve it first.

hey C@W has anyone told you that if you stare at your pathtag design long enough it starts to look like a big nosed buck tooth face with a moustache?
sorry not meaning to insult, but i just caught the image out of the corner of my eye,and thought, hey What a big nose he has!
sorry..
we now return you to your regular programmed geocaching forum.

There is a pathtag by Z that contains multiple puzzles on it for multiple caches! Now that's one way to really make you think.

Ooh, I've always wondered how to do an image steganograph. Not so easy without something like photoshop.

iSteg for mac looks pretty good if you have a mac..........

Actually it can be done with Notepad. PNGs have the capacity for a comment in the image which doesn't do anything to change the actualy image.

Most of the puzzles are BMPs, can you still use Notepad for BMPs? If so, can you explain it please?! I am sure we are all interested

Don't know about embedding text in BMPs. Here is a png with an embedded political message. Knock yourself out.

I got interested in this after reading a Tom Clancy Novel. I placed a cache (GC2MK3B) using this techniquie. I tried the notepad combination method, which worked on my PC but for some reason after uploading the images to GC, dragging them back did not allow me to get the txt file out of the image. I found a simple program on the net, JPHSwin, which worked well, and the cache was born.

It's probably because if the image is:
1: Not a JPG
2: Wider than 600 pixels
3: Bigger than 120k

The image will be converted and the embedded secret will be lost.
