Hactool Prodkeys Does Not Exist Link

hactool --keyset=~/.switch/prod.keys game.nca

Or, if you prefer it in the current folder:

cp ~/.switch/prod.keys .
hactool game.nca

When you run hactool (a tool for inspecting Nintendo Switch file formats like NCA, NRO, XCI, etc.), it requires a file called prod.keys to decrypt and parse certain protected content.
If hactool cannot find this file at the expected location, you’ll see an error similar to: hactool prodkeys does not exist link

hactool: prod.keys does not exist

Or, if you’re dealing with a symbolic link issue:

hactool: cannot link prod.keys

The error means:

You have the file, but hactool is looking in the wrong directory. By default, hactool searches:

If you do not have the file, you must dump it from your Switch. hactool --keyset=~/

The file must be named exactly prod.keys. Not prod.key, not product.keys, not prod.keys.txt. Windows sometimes hides file extensions; you might have accidentally created prod.keys.txt without realizing it.

Make sure the file is readable:

chmod 644 prod.keys
