I was trying to find a test image so I can see if programs/code I'm trying to get working on my desktop is compatible. Your image doesn't work for me. Pixelknot is stuck on 10% "Fetching your message".

I made a test image with Pixelknot (pic related). The password is "test".

I used GIMP to write the text onto an image I found online. I used Pixelknot from the Google Play store to create the test image (and wrote an embedded message).

Did it lock up for my image (>>2346641), the image in the comment I replied to (>>2306905), or both?

The original SS image is 70KB, but Pixelknot wasn't used on the image because JFIF is present (the image has a sha256 beginning in "5a7f006").

As mentioned in this comment, Pixelknot does not have "JFIF" at the beginning of its output files:

The image I created with Pixelknot does not have the JFIF at the beginning. The image on..

>>2306905

does however. Maybe a mistake, maybe a slide, I dunno.

>Speaking of poorly written, is it possible that the developers made a mistake with the random seed generator? Using the same seed for each encryption.

There is no randomness for the seed. See method extractF5Seed(). The last 1/3 of the password string is used.

Nice find!

I wrote a script to scan all files in a directory and compare them to see if they have this signature.

[code]#!/bin/bash

PN_HASH_DESIRED_OUTPUT="3f3078870bf5ddc7c4d0e6e5941805b7a062c45d -"

for filename in .jp; do

FILE_HEADER_SHASUM_OUTPUT=$(head -c 100 $filename | shasum)

if [[ $FILE_HEADER_SHASUM_OUTPUT = $PN_HASH_DESIRED_OUTPUT ]]; then

echo "File $filename looks like it was made by Pixelknot."

fi;

done[code]

If you drop the file extension, almost every one of these filenames look like base64 encoded data. The base64url variant uses "-" and "_" instead of "+" and "/".

The Silverman pic was not made by Pixelknot. It has "JFIF" at the beginning of the file.
