I built a steganography app that embeds encrypted messages into images.

It lives here: https://stegg.alifeinbinary.com

It's as much of an art project as it is a programming project. The images that it generates are visual representations of binary code translated from the text you enter. If you enable encryption it converts it to a hash. You can download the image, send to someone along with the password and they'll be able to decrypt it by uploading it to the app. Or you can post it to the time line and send them the link. All messages are truly private. No raw text text is sent to the server.

It's not vibe coded, I made it with typescript React. The app has a link to the github repo if you want to look under the hood.

I first saw this implementation from a Harvard paper back when LLM's were still just a novelty[0]. Glad to see they got their demo site back up. Always thought it was a cool idea.

OMFG the cognitive dissonance necessary to vibe code a project with the stated goal of preventing AI scrapers. What has happened to your brain.

for anyone who wants to try a consumer grade stegongraphy in browser. I built some thing here. Its free and loads a static page with a wasm binary. Once the page loads everything is handled in the browser.

You provide a carrier file (currently .mp4, .pdf, .jpeg or .png ) and impregnate it with an entire encrypted file system with a full viewer and gallery mode. Also supports streaming, so you can actually encrypt a a full blueray movie and run range requests.

Even as someone extremely firmly on the other side of the AI debate, I must appreciate the craft.

Now, to give Claude the steganogravy skill...

I wonder if you can construct a function between the encoder and decoder such that for any given input, both the raw and manipulated embeddings decode to plausible meanings that are guaranteed to be different.

Great way to hide your alchemical texts.

Really enjoyed the design/theme of this site!

Ha! I've been thinking of this exact thing, and was curious how natural-looking the end result would be / how much you could compress the tokens by choosing less and less likely ones until it became obvious gibberish. I'm kinda surprised that it just sounds like normal slop at that density. Seems viable to use with "just" two bots chattering away at each other, and also occasionally sending meaningful packets.

Pro-tip from unfrozen caveman lawyer: "Your honor. My client want hide thing from t-rex lang mo-del. He have big brain. So he not put thing on Al Gore device with series of tubes. (Unlike many on modern-day BBS called Haxer News.) T-rex not eat what t-rex not find."
