How to Dump Keys

In order to play games in XCI or NCA format, you must have the required keys to decrypt them.

Process

Guide on how to obtain the decryptions keys.

• Requirements: A hackable Nintendo Switch (you can check whether your Nintendo Switch is hackable or not here.)
• A Micro SD card of at least 1 Gigabyte in capacity.
• A Micro SD card reader.
• Lockpick: Is included by default in Kosmos CFW if you don’t use that you can download it here.
• The necessary tools (i.e a jig, paperclip, etc.) required to be able to boot into RCM and navigate around the Hekate menu.
• TegraRCMGUI or TegraRCMSmash.

You can skip to Step 3 if you already have CFW set-up.

• Step 1: Turn off your Nintendo Switch and plug your Micro SD card into your computer.
• Step 2: Download the latest Kosmos CFW (If you already have that or use a different CFW software download the latest Lockpick. and extract than in your “/switch/” folder) and extract the zip in the root of your Micro SD card.
• Step 3: Put your SD card back in your Nintendo Switch, boot into RCM mode and inject the latest Hekate payload * using your preferred payload injector.
• Step 4a: Using the VOL and Power buttons to navigate, select Console info…
• Step 4b: Select Print fuse info (not kfuse info!) and press the Power button to save fuse info to your Micro SD card.
• Step 4c: Return back to Console info… and select Print TSEC keys and press the Power button to save TSEC keys to your Micro SD card.
• Step 5: Boot into your CFW of choice, and open the Homebrew Menu (Album application).
• Step 6: Run Lockpick.
• Step 7: Turn you Nintendo Switch off and plug your Micro SD card into your computer.
• Step 8: Locate to the /switch/ folder on your Micro SD card where you’ll find two .keys files; prod.keys and title.keys, copy these and paste them into the &appdata&/yuzu/keys/ folder.

And you’re done! Congratulations! You’ve just dumped your decryption and title keys!
