: The file is named incorrectly (e.g., prod.keys.txt instead of prod.keys ).
The [WARN] prod.keys does not exist message is one of the most misunderstood and feared outputs in the Switch modding toolkit. But as we've seen, for the vast majority of users, it is a harmless notification, not a fatal error. It's a bit of nagging from a tool that's thorough in its checks, even when those checks aren't required for the task at hand.
Depending on what specific file type you are trying to decrypt, production keys alone may not be enough. If you are decrypting game titles or downloadable content (DLC), hactool might also require a title.keys file. hactool prodkeys does not exist top
By explicitly defining the path, you bypass hactool's automated directory search entirely, eliminating the pathing error. Alternative Solutions: Title Keys

Encryption keys are copyrighted material property of Nintendo. You must dump these keys legally from your own physically owned, modified Nintendo Switch console using homebrew tools like Lockpick_RCM. Downloading these files from third-party websites violates copyright laws and poses malware risks. To help you get everything running smoothly, let me know: Which are you currently using?
The prod.keys file is the linchpin of the entire Nintendo Switch encryption system. This file contains a collection of cryptographic keys necessary to decrypt and make sense of the various encrypted components of Switch titles and system software. Without these keys, the hactool tool can still work with unencrypted files, but any attempt to access the secure parts of an encrypted file would result in gibberish data.
