To apply the keys, you must place the text file into the specialized core directory of your chosen emulation software:
This comprehensive guide explains exactly what the aes-keys.txt file is, how the Nintendo 3DS uses security keys, how to legally obtain them from your own hardware, and how to set them up for a flawless emulation experience. What is aes-keys.txt?

That said, the humble 3ds aes-keys.txt remains the most portable, human-readable, and widely supported format. It will likely remain relevant for another decade, as long as people still play The Legend of Zelda: A Link Between Worlds or Pokémon Omega Ruby on PC. 3ds aes-keys.txt
He saved it.

Used to decrypt system applications, system updates, and general container assets. To apply the keys, you must place the
Once you have your text file ready, you must place it in the correct directory so your emulator can detect it automatically. For Citra (and modern forks)

Shared across all retail 3DS systems to decrypt system applications and standard software.
Without these cryptographic keys, an emulator cannot read the encrypted data inside 3DS game files (such as .3ds , .cia , or .cxi ), resulting in errors like "The ROM is encrypted" or a failure to launch.
This ensures you aren't downloading potentially malicious files (hackers love hiding malware in fake "keys" archives) and keeps your usage legally defensible for backup purposes.
