Never mind, I did a quick experiment with the tool from Cryptologia and a minor change to the code and the right settings (once I read the comment in the text)…

Can someone give me a hint or nudge on how to attack/solve this problem?
Please send me an email and what you tried with Sage. I guess I can gi…
