The utility automatically utilizes the 3DS's own hardware AES engine to cleanly dump the required keys into a standardized text file format ( aes_keys.txt or encTitleKeys.bin ). A Note on Legality

The Nintendo 3DS uses AES (Advanced Encryption Standard) keys for various cryptographic purposes, including encrypting and decrypting data, such as game cartridges, DSiWare, and other content.

Emulators like Citra , Lime3DS , and Folium require a file named aes_keys.txt to play encrypted games.

Nintendo fought back by introducing the slot0x15 key in system update 6.0.0, but even that was eventually leaked in 2015 following the release of the "New 3DS" and subsequent hardware exploits.
