You must dump it from your own Nintendo Switch console using tools like:

The dumped file will be named prod.keys. Keep it private – sharing it is illegal and exposes your console.

hactool is an open-source command-line tool developed by the Switch reverse engineering community (primarily by Simon "SciresM" Aarons and the switch-tools team). It is designed to parse and decrypt various Nintendo Switch file formats, including:

Without hactool, extracting game assets (models, textures, sound files) or analyzing system updates would be nearly impossible for homebrew developers and researchers. However, due to encryption, hactool cannot work alone. For the end-user, however, the error is infamously cryptic

If you are delving into the world of Nintendo Switch file extraction, game modding, or firmware analysis, you have likely encountered the hactool utility.
