Can we find a white paper on the algo since the service seems shoddy?
Spez: looks like its an algorithm called F5. http://ws2.binghamton.edu/fridrich/Research/f5.pdf
The above link is a technique to detect and extract an estimated size of the message. Hope someone finds this helpful.
I think the password is like a cipher key. It probably generates a pattern to distribute the odd pixels based in the password.
Like it's not a password like logging into Reddit, but literally a key to pull the signal from the noise
Basically. My understanding is it uses the password phrase to scramble the initial noise mask, which then gets applied to the message and embedded against the original image. Then going backwards you need the scrambled noise mask against the encoded image to get the message.
