To play encrypted Nintendo 3DS games on the Citra emulator, you must provide a file named aes_keys.txt . This file contains the cryptographic keys needed to decrypt and run game data from .3ds or .cia files.
Nintendo uses Advanced Encryption Standard (AES) hardware encryption to protect its 3DS game software from piracy. Games distributed digitally via the Nintendo eShop (CIA files) or dumped directly from game cartridges (CCI or 3DS files) are often encrypted.
These are direct, raw dumps from a 3DS cartridge or system storage. They retain Nintendo's original security layout and strictly require the aes_keys.txt file to run on Citra.
