Example sanitized excerpt from 3ds aes-keys.txt (not real keys):

However, this power comes with a responsibility. The most ethical and legally sound path for any user is to own a physical 3DS console and to obtain their keys and game ROMs directly from their own hardware, using the automated GodMode9 script. By doing so, you are not only protecting yourself from legal risks but also supporting a culture of preservation that respects the work of developers and the principle of fair use. The aes_keys.txt file is a tool; what matters most is how you choose to use it.

Before we proceed to usage, a serious disclaimer is required.

When a game is inserted into the 3DS, the console uses the encryption keys from the aes-keys.txt file to decrypt the game's content. This process ensures that only authorized games can be played on the console, and that piracy is prevented.

This is crucial. Every 3DS game has a 16-byte "Title Key" encrypted with a console-specific key. However, the system uses a fixed AES key to decrypt that Title Key from the game's ticket. Having the correct slot0x11Key95 allows you to generate valid title keys for games.

: Distributing or obtaining encryption keys without authorization can violate copyright laws and terms of service. It's essential to ensure that any handling of such data is legal and ethical.

You might have a CIA file (downloaded from the eShop or dumped from a digital copy) and want a .3ds file (for flashcarts or emulators). You can use makerom or cia2cci with the command:

As of 2024-2025, the 3DS eShop is closed, and the official Citra emulator has been discontinued (due to the Yuzu lawsuit fallout). However, the 3ds aes-keys.txt file remains critically important for three reasons:

Proponents argue that the keys are essential for "format shifting" and the long-term preservation of digital media, especially as the 3DS eShop has closed. 6. Conclusion

Perhaps the most complex aspect of the aes_keys.txt discussion is its legal status. The act of using these keys to decrypt and play a game on an emulator touches on several key points of intellectual property law, particularly the rules regarding Digital Rights Management (DRM) and Technological Protection Measures (TPMs).
