Keys are required for decrypting most of the file formats used by the Nintendo Switch.
|
||||
|
||||
Keysets are stored as text files. These 3 filenames are automatically read:
|
||||
`prod.keys` - Contains common keys usedy by all Switch devices.
|
||||
`console.keys` - Contains console-unique keys.
|
||||
`title.keys` - Contains game-specific keys.

* `prod.keys` - Contains common keys used by all Nintendo Switch devices.
|
||||
* `title.keys` - Contains game-specific keys.
|
||||
|
||||
Ryujinx will first look for keys in `RyuFS/system`, and if it doesn't find any there it will look in `$HOME/.switch`.
|
||||
|
||||
A guide to assist with dumping your own keys can be found [here](https://gist.github.com/roblabla/d8358ab058bbe3b00614740dcba4f208).
|
||||
|
||||
## Common keys
|
||||
|
||||
Here is a template for a key file containing the main keys Ryujinx uses to read content files.
|
||||
Both `prod.keys` and `console.keys` use this format.
|
||||
|
||||
```
|
||||
master_key_00 = XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
|
||||
master_key_01 = XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
|
||||
master_key_02 = XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
|
||||
master_key_03 = XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
|
||||
master_key_04 = XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
|
||||
master_key_05 = XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
|
||||
|
||||
titlekek_source = XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
|
||||
key_area_key_application_source = XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
|
||||
key_area_key_ocean_source = XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
|
||||
key_area_key_system_source = XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
|
||||
aes_kek_generation_source = XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
|
||||
aes_key_generation_source = XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
|
||||
header_kek_source = XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
|
||||
header_key_source = XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
|
||||
```
|
||||
To dump your `prod.keys` and `title.keys` please follow these following steps.
|
||||
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.
|
||||
3. Download the latest release of [Lockpick_RCM](https://github.com/shchmue/Lockpick_RCM/releases).
|
||||
4. Boot into RCM mode.
|
||||
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.
|
||||
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.
|
||||
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`.
|
||||
10. You can find your keys in `sd:/switch/prod.keys` and `sd:/switch/title.keys` respectively.
|
||||
11. Copy these files and paste them in `RyuFS/system`.
|
||||
And you're done!
|
||||
|
||||
## 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:
|
||||
|
||||
```
|
||||
01000000000100000000000000000003,XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
|
||||
01000000000108000000000000000003,XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
|
||||
01000000000108000000000000000004,XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
|
||||
01000000000100000000000000000003 = XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
|
||||
01000000000108000000000000000003 = XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
|
||||
01000000000108000000000000000004 = XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
|
||||
```

These are typically used to decrypt system files and encrypted game files. These keys get changed in about every major system update, so make sure to keep your keys up-to-date if you want to play newer games!
