I am trying this program out right now on a Raspberry Pi 3B+ and I see that at any given time it is only using 1 core and not all 4. Will there be any future development with this? We await your response!

This is an excellent tool, and the code is sensible enough. Restart functionality is just made for AWS spot instances. Does not multi-thread. Simple enough to extend to accept "start" and "end" keys for splitting work. All sorts of extensions are possible. Some of the key constants could have been in a header file. By default does not start with short length passwords. Could unroll some loops too, but still pretty quick.

Very well structured. Command line options were just what I expected. My case was easy because I knew the structure of my password and had just forgotten one part. I built a wordlist and pdfcrack solved my problem in one second.
