# Keys
|
|
|
|
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.
|
|
|
|
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
|
|
```
|
|
|
|
## Title keys
|
|
|
|
Title keys are stored in the format `rights_id,key`.
|
|
|
|
For example:
|
|
|
|
```
|
|
01000000000100000000000000000003,XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
|
|
01000000000108000000000000000003,XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
|
|
01000000000108000000000000000004,XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
|
|
```
|
|
|
|
## Complete key list
