I'm confused here. Stegseek works on things encrypted with steghide. steghide doesn't use F5 algorithm which is what PixelKnot uses. The F5 algorithm is funded by AFRL (airforce research lab). So, my bet is that we need to use an F5 algorithm based steg decrypter.

Wow.. so, looks like I can run a decryption in a couple seconds by directly using the f5 library referenced by PixelKnot:

And running with:
java -jar f5.jar x -p 'POTUS45' image.jpg
Make sure the file ends with .jpg. For some reason, the tool doesn't like files with .jpeg extension.
