- >What prevents us from getting into Sun and Moon early?
- Three layers of protection.
- -The games' encrypted content need to be uploaded to the CDN. (EDIT 10/31/2016: They have been uploaded).
- -The games' titlekey needs to be made available (this is equivalent to saying the games must be purchasable).
- -The games' content lock seeds need to be made available.
- >What's a titlekey?
- A titlekey is a 128-bit number, that's the key to decrypting the content on the CDN.
- Titlekeys get delivered to your console when you purchase a game -- there's no way to get one otherwise.
- Thus, we will not have the titlekeys before release or Nintendo making them pre-purchasable, whichever comes first.
- >Nintendo made the game's prepurchasable. Why can't we decrypt them?
- In addition to the normal CDN crypto, sun and moon will use a content_lock seed protection system.
- In addition to the normal encryption on every 3ds game, Sun and Moon will have a 128-bit "content lock seed", used to encrypt the games.
- Without this value, the games can't be decrypted, even if you've installed them via pre-purchasing. Nintendo is not stupid, and has not released this value.
- The "small update" you download on release date for a pre-purchased game consists entirely of this 128-bit content lock seed, which gets published on release.
- >What does all this mean?
- -The games will probably be uploaded to the CDN in the next week or two.
- -The games may not be prepurchasable. If they're not, they're doubly protected.
- -If they are prepurchasable, they're still protected by a 128-bit value, which nobody can brute-force before the universe dies.
- All in all, nobody's going to be getting into Sun/Moon early via the eShop, because nobody has the titlekey, and nobody has the content lock seed.
- If anyone gets the games early, it will be via cartridge leaks.
