+# 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
+```
