Distributing them alongside open-source tools would lead to immediate legal takedowns. Therefore, the developers of hactool designed it to look for an external file named prod.keys (or dev.keys for development units) in specific locations.

There is no friendly "Browse" button, no settings menu to point it to the right location. It is command-line purism at its finest.
However, it is notoriously finicky during the initial setup. One of the most common roadblocks users face is the dreaded error message: .
