hactool expects the prod.keys file to be in specific locations, primarily the user's home configuration folder or the same directory as the executable.
这条"prod.keys does not exist"本质上是一个信息提示，而非致命错误。举例来说，在处理NSO（Nintendo Switch Object）解压缩时，hactool的 -t nso0 参数完全不依赖任何密钥文件就能正常运行，因此即使看到这条警告，也不妨碍操作成功。
However, one of the most common and frustrating roadblocks for beginners (and even experienced users) is the infamous error message:
此方案最可靠，直接通过命令行参数告诉工具你的密钥文件在哪里。例如，假设你把密钥文件放在 D:\Switch\prod.keys ，可以执行： hactool prodkeys does not exist top
If it’s empty or contains garbled text, the dump failed — re-dump from your Switch.

hactool is a command-line utility used to view information about, decrypt, and extract Nintendo Switch file formats [1]. However, it does not come packaged with the necessary decryption keys due to copyright laws. hactool expects the prod
If you edited prod.keys on Windows using Notepad, it might have saved with CRLF line endings. Some versions of hactool on Linux/macOS dislike this. Use dos2unix to fix:

Leo pushed his chair back, the wheels screeching against the floorboards. He grabbed his phone and dove into the forums. He typed the error message into the search bar. However, it does not come packaged with the
If using a build/package that expects a different filename, pass it with --keys or consult that build’s docs.
If you are only extracting data from NCA files that do not require high-level decryption, this warning can sometimes be ignored. If hactool proceeds despite the warning, you can ignore it. To hide the warning, you can use the flag: --disablekeywarns Use code with caution. Summary Checklist used to generate keys? prod.keys file in ~/.switch/ or hactool folder?
