Windows sometimes hides file extensions. Ensure your file is named exactly prod.keys and not prod.keys.txt .
These keys are collectively stored in a text file usually named prod.keys (production keys).

If you are trying to decrypt a brand-new game, your prod.keys might be missing the newest "Master Key" required for that specific firmware level. If this happens, update your Nintendo Switch system firmware and re-run Lockpick_RCM to get an updated key file. hactool prodkeys does not exist link
Place the Lockpick_RCM.bin payload into the bootloader/payloads folder on your Switch's SD card.
Ensure your Switch is unpatched and capable of running Custom Firmware (CFW).
When creating the .switch folder, remember the leading dot. In Windows, you may need to name the folder .switch. in File Explorer to force it to accept the starting period.
Download the latest release of from a trusted homebrew repository. ls -l prod
mkdir -p ~/.switch cp /path/to/prod.keys ~/.switch/
: Connect your Switch to your PC and use a tool like TegraRCMGUI (Windows) or WebRCM to inject the Lockpick_RCM.bin payload.
Place prod.keys in %APPDATA%\hactool\ (on Windows). 3. Verify Filename Ensure the file is explicitly named:

A hackable Nintendo Switch console (capable of booting into RCM/Homebrew). An SD card reader.
This is the most reliable method as it leaves no room for ambiguity.
is a command-line program designed to decrypt, extract, and view the contents of Nintendo Switch file formats (NCA, NRO, NSO, XCI, etc.). However, all modern Nintendo Switch software is heavily encrypted. Without the correct cryptographic keys, the files look like random garbage data.
If you see "header decryption failed," your prod.keys might be from an older firmware version. You will need to update your Switch firmware and re-run Lockpick_RCM to get the latest master keys.
