Nintendo no longer actively produces 3DS games or system updates as of 2024. The console is in "end-of-life" status. This means that once you have a full set of slot keys (0x11 through 0x1B) and a complete titlekey set, your aeskeys.txt will work forever.
No future system update will change these keys. The "3ds aeskeystxt work" problem will eventually vanish as all working keys become standardized.
Titlekeys are unique per game revision. If you have Pokemon Sun (Rev 0) but your ROM is Pokemon Sun (Rev 1), the titlekey will not work. Moreover, Nintendo continuously issues new system updates that change key behavior.
Say you have a decrypted .3ds file and want to re-encrypt it for a different console:
Older aeskeys.txt files lack the slot0x18Key (also known as the "Malleo" key) and slot0x1B keys, which are required for newer 3DS system versions and certain ROMs (like Mario & Luigi: Superstar Saga + Bowser's Minions).
aes_keys.txt works as a modular, external keyring for 3DS cryptographic tools.
