    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.

    kcylsnavs: What's the problem with doing "pdfcrack -h" and getting the options listed for you? What more do you want?

    Perfect program. My configuration: Intel core i3 4GB RAM Ubuntu 12.04 20 hours = found user-password 'xxxxxx' six characters!!!

    No documentation whatsoever, other than a terse help file. Works with encrypted PDF's only, if is merely password protected the program simply asks you that but provides no guidance on what to do if it is.

    Some annoyances can't be evaded by simply switching to Linux.
