prod.keys holds the console-wide keys that every game needs; title.keys holds one key per game, update or DLC for content distributed with a ticket. Lichii always needs prod.keys and needs title.keys only for some dumps.
| prod.keys | title.keys | |
|---|---|---|
| Scope | Whole console | One game, update or DLC per line |
| Needed by | Every game and firmware | Ticket-based dumps without their ticket |
| Line format | key_name = value | rights_id = title_key |
| Size | A few hundred lines at most | Grows with every new game |
| Changes when | A system update adds a key generation | New games are released |
| Without it | Encryption keys are missing | Missing title key for that game |
What is a title key?
A title key is the per-game key that decrypts content distributed digitally. It is stored inside a ticket, encrypted with the titlekek from prod.keys; title.keys lists the title keys already decrypted.
What is a rights ID?
A rights ID is the 32-character identifier that links a piece of content to its ticket and title key. It is the left side of every title.keys line.
Do you need both files?
You need prod.keys always. You need title.keys when Lichii reports a missing title key for a game; complete dumps with their tickets do not need it.
