Ryujinx will first look for keys in `RyuFS/system`, and if it doesn't find any there it will look in `$HOME/.switch`. Ryujinx will first look for keys in `RyuFS/system`, and if it doesn't find any there it will look in `$HOME/.switch`.
To dump your `prod.keys` and `title.keys` please follow these following steps.
A guide to assist with dumping your own keys can be found [here](https://gist.github.com/roblabla/d8358ab058bbe3b00614740dcba4f208). 1. First off learn how to boot into RCM mode and inject payloads if you haven't already. This can be done [here](https://nh-server.github.io/switch-guide/).
2. Make sure you have an SD card with the latest release of [Atmosphere](https://github.com/Atmosphere-NX/Atmosphere/releases) inserted into your Nintendo Switch.
## Common keys 3. Download the latest release of [Lockpick_RCM](https://github.com/shchmue/Lockpick_RCM/releases).
4. Boot into RCM mode.
Here is a template for a key file containing the main keys Ryujinx uses to read content files. 5. Inject the `Lockpick_RCM.bin` that you have downloaded at `Step 3.` using your preferred payload injector. We recommend [TegraRCMGUI](https://github.com/eliboa/TegraRcmGUI/releases) as it is easy to use and has a decent feature set.
Both `prod.keys` and `console.keys` use this format. 6. Using the `Vol+/-` buttons to navigate and the `Power` button to select, select `Dump from SysNAND | Key generation: X` ("X" depends on your Nintendo Switch's firmware version)
7. The dumping process may take a while depending on how many titles you have installed.
``` 8. After its completion press any button to return to the main menu of Lockpick_RCM.
master_key_00 = XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX 9. Navigate to and select `Power off` if you have an SD card reader. Or you could Navigate and select `Reboot (RCM)` if you want to mount your SD card using `TegraRCMGUI > Tools > Memloader V3 > MMC - SD Card`.
master_key_01 = XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX 10. You can find your keys in `sd:/switch/prod.keys` and `sd:/switch/title.keys` respectively.
master_key_02 = XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX 11. Copy these files and paste them in `RyuFS/system`.
master_key_03 = XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX And you're done!
master_key_04 = XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
master_key_05 = XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
titlekek_source = XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX

## Title keys ## Title keys
Title keys are stored in the format `rights_id,key`. These are only used for games that are not dumped from cartridges but from games downloaded from the Nintendo eShop, these are also only used if the eShop dump does *not* have a `ticket`. If the game does have a ticket, Ryujinx will read the key directly from that ticket.
Title keys are stored in the format `rights_id = key`.
For example: For example:
``` ```
01000000000100000000000000000003,XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX 01000000000100000000000000000003 = XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
01000000000108000000000000000003,XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX 01000000000108000000000000000003 = XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
01000000000108000000000000000004,XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX 01000000000108000000000000000004 = XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
``` ```
