The encryption works like a lock, and the "AES Keys" are the keys to that lock. Without the correct keys, Citra cannot decipher the game data, resulting in a black screen or a crash. Citra does not come with these keys pre-installed for legal reasons (distributing copyrighted decryption keys would open the developers up to lawsuits). Therefore, the user must supply them manually.
Citra is a popular open-source emulator that allows you to play Nintendo 3DS games on your computer. It supports various operating systems, including Windows, macOS, and Linux. Citra works by mimicking the 3DS console's hardware and software, enabling you to run 3DS games on your PC.
