Remember the golden rule of homebrew: Always dump your own keys. Not only does it keep you legal, but it guarantees that hactool will work with your specific dumps.
If you are a Nintendo Switch homebrew enthusiast, a reverse engineer, or someone trying to dump or decrypt your own game files, you have likely encountered the frustrating hactool error: "Failed to locate prod.keys." or "prod.keys does not exist." C:\hactool\ ├── hactool
This error halts your progress immediately. You cannot decrypt NCA files, view program metadata, or extract game assets without solving it.
hactool --keyset=D:\switch\prod.keys game.nca This overrides all other search locations and is the most reliable method. For power users who run hactool from many locations, set the HACTOOL_KEYS_FILE environment variable. If you are a Nintendo Switch homebrew enthusiast,
export HACTOOL_KEYS_FILE=/home/user/keys/prod.keys
