Bot defeated thanks @DarthCoin
hahahaha nice!
But man, be more creative and put another title for the note, something like a riddle, like a secret message, or a haiku :)
Make it PoW
Fun fact: in one of my guides I put 12 words (from a real wallet) in plain sight! Find them if you can.

I love a hunt!
Does the wallet still contain a prize? Would you reveal the address that holds the prize, so hunters can check if the prize is still there (in the future), and if the prize is worth the effort?

The most canonical version of this image that I know of is the one from your GitHub repository in https://github.com/Darth-Coin/darth-coin.github.io/blob/main/assets/images/
But it's a .jpg
$ mediainfo cats-stego.jpg
General
Complete name : cats-stego.jpg
Format : JPEG
File size : 38.4 KiB
Image
Format : JPEG
Width : 640 pixels
Height : 480 pixels
Color space : YUV
Chroma subsampling : 4:2:0
Bit depth : 8 bits
Compression mode : Lossy
Stream size : 38.4 KiB (100%)
Does that even still contain the steganographic data?
Is there a method to convert a TIFF (written by OpenStego) to a JPG so it retains the information?
Or would I have to put the TIFF itself on the web?
You allude to this in your guide
I can send this photo to anyone (it is necessary without digital alterations/ compression) anywhere in the world, without anyone knowing that this photo contains 1BTC. Or I can even have it as a desktop background or in a digital photo frame-box.
Is the cat image in your guide still containing the secret data, or is this just an illustration of the concept? If it still contains the secret data, how does one create such a JPG file?

check also these tools you can play with:

Thanks I’ll add them to the list of bot busters!
What you inspect is a copy. When you copy the file with stego info is losing the embedded data from stego.
Only the original file contain it.
By saying that "I can send this image to somebody else" I mean I will use the ORIGINAL file that I used in stego, not a copy.
So people looking to "decrypt" this file posted online, will find nothing in fact.
reply
Ah, I understand.
When I want to put such an image of my own somewhere public, it's a little suspicious if I post a large .tif file. People might immediately suspect it contains stego.
I was wondering if you had found an elegant way of losslessly compressing it to .jpg.
Best I could think of is ImageMagick's convert image.tif image.jp2 (where JPEG 2000 can contain losslessly compressed data), then rename to image.jpg.
I've seen that before, but you being DarthCoin, I always assumed this to be cryptographically secure steganography with a strong password.
Is this a hunt, where an amateur can realistically figure out the seed words from the picture?
Or a I dare you break this AES-256 encryption without any key information, knowing full well nobody can, hence not risking any Bitcoin at all?
reply
then good luck finding the 12 words in my guide.
reply
I studied https://darth-coin.github.io/beginner/be-your-own-bank-en.html where that image is present.
The "Madness in plain sight" paragraph mentions the 12 words. But if I were to follow your guide and hide my own 12 words in a document of my own, to reconstruct them later, how would I later
- identify which words were special to me
- in what order they go in the passphrase (if not from first to last)
I notice there are about 12 worlds like “cleanliness” in quotation marks. But putting those, in order, in OpenStego doesn't work. As you note
Even if you think about it, they have many years of trying until they can find the order …
But how would I, in the future, deduce the right order?
BTW, your explanation of PublicNote
This algorithm (which is open source and you can take it offline if you want) makes an encryption of this text resulting in another text
can be dangerously misunderstood: Yes, the software is open source and you can run your own instance. But the data is stored on the server, and when the server goes offline (your own server can vanish, too!), you can't follow these breadcrumbs anymore. If you stored your texts on the public server, and that goes away, you can't install your own server from the open source to get the texts back.
