I'm curious how visible changes are in the picture and what happen if you use an image which already had a message hidden. So I'm going to try I guess. I could do this in /test/ but maybe someone will be interested. (I also guess there is some article about this somewhere, but I'm too lazy to look it up.)

stegno thread? What is the best way to get hidden data out of images? pic related, I found this picture on the google machine, The colour stripe on the side made me think it might have hidden data in it

>>41 This is what I am trying to figure out as well. I am going to try with all white and all black images to see if visible changes shake out.

>>198 >>200 You can hide a message around ~12% of the size of the original image. But size as in "information content", and a plain black or white rectangle has basically no information stored (it can be perfectly summed up by its dimensions and its colour). Thus you can't hide a message inside.

>>1415 Follow the sticky guide. On firefox you have to enable the greasemonkey userscript per site. (gmonkey / DDT / options / includes) The default broadcast address is 'desu' in each of the 3 fields (danger zone, if you changed it) Reloading and opening a thread (via catalog for ex) helps.

The github says it's a steganography tool but i see nothing about steganography..

I've tried here and other chans, and no dice on getting it to work with and without 4chanx and other scripts running. Absolute tragedy.

Trinity · 2023-11-26 21:23

>>1870 Yeah I'm having trouble with it too. When I hit encrypt and send, the site complains my post looks automated so it discards it.
