The "hactool prodkeys does not exist" error is not a bug; it is a standard security protocol telling you that the program lacks the necessary decryption components. By dumping your prod.keys using Lockpick_RCM, renaming the file properly, and placing it either in the hactool directory or your global .switch folder, you can successfully bypass this error and proceed with your file extraction.
hactool --keyset=./my_keys/prod.keys game.nca
mkdir -p ~/.switch cp /path/to/dumped/prod.keys ~/.switch/
Ironically, the error’s opacity forces users to learn about the Switch’s security architecture. It is a painful but effective educational tool, turning a simple file-missing error into a lesson in cryptographic key hierarchies.
A frequent trap for Windows users is the "double extension" bug. Windows often hides known file extensions by default.
When running your command, append the -k or --keyset switch followed by the path to your keys: hactool -k path/to/prod.keys -t xci yourgame.xci Use code with caution.
You can explicitly tell hactool where the keys are using the -k flag.
By default, Windows hactool looks for keys in your user profile directory.
hactool doesn't just check for the existence of prod.keys ; it also scans the file itself. You might see additional warnings like:
If you are still experiencing issues, quickly run through this final checklist: Is the file name exactly prod.keys (all lowercase)?
