SHA-1 hashes : 76d31f51a205e93adacf08564f3180e106304494 : pdfcrack (backend tool) 7c538124c850bda016471f7feb0c8492466696f0 : pdfcrack-gui (GUI tool)

It comes precompiled as a Linux 64-bit binary, only. Both were compiled on Linux Mint 19.3.

This project in no way aims to replace pdfcrack. The gui is 100% reliant on pdfcrack itself and is simply a friendly front end to it.

Just double click pdfcrack-gui to launch, or to execute from the command line :

./pdfcrack-gui

If the program does not run after download, be sure to make both pdfcrack and pdfcrackgui are present in the same folder, and executable :

chmod +x *
