Aes-keys.txt Citra
Technically, it may work, but it is legally dubious. More importantly, sharing keys ties you to their console’s unique key layout. If they later dump DLC or updates, it may mismatch. Dump your own.
To run encrypted 3DS games on the Citra emulator (and its derivatives like Folium), you must provide decryption keys in a file named aes_keys.txt. Without this file, Citra will display an "encrypted" error when you try to launch your games. Where to Place the File
The aes_keys.txt file must be placed in the sysdata subfolder of your Citra user directory. The exact path depends on your operating system: Windows: C:\Users\[Your_Name]\AppData\Roaming\Citra\sysdata
Linux/Steam Deck: ~/.local/share/citra-emu/sysdata or ~/.var/app/org.citra_emu.citra/data/citra-emu/sysdata for Flatpak macOS: ~/Library/Application Support/Citra/sysdata
Android/iOS: Typically found within the app's internal "sysdata" folder accessible via a file manager How to Obtain aes_keys.txt
There are two primary ways to handle the "encrypted ROM" issue:
In the context of the Citra emulator, aes_keys.txt is a system file required to decrypt and load encrypted Nintendo 3DS games (ROMs). Without these keys, Citra cannot access the game data, often resulting in errors like "must be decrypted first". Where to Place the File
The file must be named exactly aes_keys.txt and placed in the sysdata folder within your Citra user directory. If the folder does not exist, you must create it manually.
Windows: C:\Users\ Android: Internal memory/citra-emu/sysdata/ macOS: ~/Library/Application Support/Citra/sysdata/
Linux (Steam Deck): /home/.var/app/org.citra_emu.citra/data/citra-emu/sysdata/ How to Obtain the File
While "good papers" or guides often point to existing lists, the most legal and reliable way is to dump the keys from your own 3DS console using custom firmware.
Use GodMode9: On a modded 3DS, run a script like dumpkeys.gm9 .
Locate the Output: The console will generate the file at sd:/gm9/aes_keys.txt.
Transfer: Copy this file to the specific sysdata path for your device listed above. Common Issues
Encrypted .CIA Files: If you are trying to install .cia files and they fail even with the keys, they may need to be decrypted first using external tools, or you should source .3ds or .cci formats.
Alternative: To avoid managing keys entirely, many users choose to download pre-decrypted ROMs, which Citra can play immediately without an aes_keys.txt file.

Understand the difference between encrypted and decrypted ROMs. CITRA: bios support for AES Keys · Issue #270 - GitHub
The world of emulation was abuzz with excitement as Citra, the popular Nintendo 3DS emulator, continued to improve with each new update. One of the key factors in Citra's success was its ability to accurately replicate the 3DS's complex encryption methods, including the use of AES keys.
For those who didn't know, AES (Advanced Encryption Standard) keys were a crucial part of the 3DS's security system. These keys were used to encrypt and decrypt game data, ensuring that only authorized software could access and play games on the console.
But for Citra users, having access to these AES keys was essential for playing games. That's where the "aes-keys.txt" file came in. This file contained a list of AES keys that Citra could use to decrypt and play 3DS games.
The story begins with a young programmer named Alex, who had been working on Citra for months. Alex was determined to get the emulator working perfectly, and he spent countless hours poring over lines of code and testing different configurations.
One day, while browsing through the Citra forums, Alex stumbled upon a post from a user who claimed to have discovered a way to extract the AES keys from a 3DS console. The user, known only by their handle "3DS_Hacker," had uploaded a file containing the AES keys, along with instructions on how to use them with Citra.
Alex was intrigued, and he quickly downloaded the file, which was named "aes-keys.txt." He carefully followed the instructions, making sure to configure Citra correctly and place the aes-keys.txt file in the right directory.
To his delight, Alex found that Citra was now able to play 3DS games with ease. The emulator was able to decrypt the game data using the AES keys, and the games ran smoothly and without any issues.
As news of the aes-keys.txt file spread, Citra users from all over the world began to download and use it. The file became a sort of holy grail for Citra enthusiasts, and it played a key role in the emulator's continued success.
But as with any powerful tool, there were also risks involved. Some users began to use the aes-keys.txt file for nefarious purposes, such as pirating games and distributing them online.
Citra's developers were aware of these risks, and they made it clear that they did not condone piracy or any other illicit activities. They encouraged users to only use the aes-keys.txt file for legitimate purposes, such as playing games they had purchased and owned. aes-keys.txt citra
Despite these risks, the aes-keys.txt file remained a crucial part of the Citra ecosystem. It was a testament to the power of community-driven development and the importance of collaboration and sharing knowledge.
And for Alex, the young programmer, the aes-keys.txt file represented a major breakthrough in his work on Citra. He continued to contribute to the emulator, and his efforts helped to make it one of the most popular and widely-used emulators in the world.
Here are some key points about Citra and AES keys:
The Essential Guide to aes_keys.txt for Citra To run encrypted Nintendo 3DS games on the Citra emulator, you must provide a file named aes_keys.txt within the emulator's system data folder. This file contains cryptographic keys that allow Citra to decrypt and boot game ROMs (such as .3ds or .cia files) and access system-level features. What is aes_keys.txt?
The aes_keys.txt file is a plain-text document that acts as a "keyring" for the Citra emulator. While Citra is an open-source project, it cannot legally include these proprietary Nintendo keys. These keys are necessary for: Game Decryption: Loading encrypted retail game dumps.
System Functions: Accessing features like Mii sharing, StreetPass data, and system-level font rendering.
CIA Installation: Allowing the emulator to install and play encrypted .cia files. How to Obtain aes_keys.txt
The legally recommended method is to dump these keys from your own Nintendo 3DS hardware.
Requirement: A Nintendo 3DS or 2DS console with custom firmware (CFW) and GodMode9 installed. Using GodMode9:
Download a "dumpkeys" script (often named dumpkeys.gm9) and place it in the /gm9/scripts/ folder on your 3DS SD card.
Boot your 3DS into GodMode9 (usually by holding Start while powering on).
Press the Home button, select Scripts, and run the DumpKeys script.
Transfer: Once the process is finished, a file named aes_keys.txt will be created on your SD card (typically in the /gm9/ folder). Where to Place the File
Once you have the file, it must be moved to the sysdata folder in your Citra User Directory. The location varies by operating system: 3DS trying to get AES keys : r/Roms

If Citra still shows an "encrypted" error, your keys might be outdated or for the wrong region. Most people find it easier to simply find a version of their game online. files using a PC tool instead?
The aes-keys.txt file is the "skeleton key" for the Citra emulator, acting as the essential bridge that allows the software to unlock and play encrypted Nintendo 3DS games. The Role of aes-keys.txt
Most 3DS games are protected by AES (Advanced Encryption Standard), a security measure designed to ensure they only run on official hardware. While Citra is a powerful emulator, it does not ship with these proprietary keys due to legal and copyright protections.
The Decryption Gap: Without this file, Citra cannot read the encrypted data within .3ds or .cia files, often resulting in errors where the game fails to load or the header is marked as "encrypted" in logs.
A "Dumping" Necessity: To play legally owned games, users must "dump" (extract) these system keys directly from their own 3DS hardware and save them into a text file named exactly aes-keys.txt. Where the Keys Live
For Citra to find these keys, they must be placed in a specific subfolder within the emulator's user directory. Standard Location: The file belongs in the sysdata folder.
Windows Path: C:\Users\[Username]\AppData\Roaming\Citra\sysdata\. macOS Path: ~/Library/Application Support/Citra/sysdata/. Linux Path: ~/.local/share/citra-emu/sysdata/.
RetroArch users: If using the Citra core in RetroArch, the file must typically be placed in ../saves/Citra/sysdata/.
The air in Leo’s room was thick with the hum of a desktop tower and the faint smell of overpriced energy drinks. On his monitor, the Citra emulator window sat stubbornly dark, a digital void where a vibrant world of pocket monsters was supposed to be. The error message was a familiar ghost: “Your ROM is encrypted. Please provide the AES keys.” Technically, it may work, but it is legally dubious
Leo sighed, leaning back until his chair groaned. To the uninitiated, "aes-keys.txt" sounded like a boring spreadsheet. To a retro-gaming enthusiast, it was the skeleton key to a locked kingdom. Without that tiny text file, the high-definition textures and smooth 60fps dreams he’d spent all afternoon configuring were just useless lines of code.
He opened his browser, the blue light reflecting in his glasses. He knew the risks. The internet was a minefield of "click here for keys" buttons that usually led to a hijacked browser or a very angry antivirus notification. He remembered his friend Mark, who had tried to find a shortcut and ended up with a computer that only spoke in pop-up ads for suspicious vitamins.
"Do it right," Leo muttered to himself. He pulled out his old, battered 3DS—the one with the peeling Pikachu sticker. This wasn't just about playing a game; it was about the ritual. He connected the handheld to his PC, his fingers dancing across the keys as he initiated the decryption process. It felt like digital archaeology, brushing away the layers of encryption to reach the preserved artifacts beneath. Slowly, the file began to take shape. aes-keys.txt.
He moved the file into the Citra folder with a satisfying click. He held his breath and hit 'Play.' The void on the screen shattered. The iconic chime of the handheld’s startup sequence filled the room, clearer and louder than his old speakers had ever managed. The world of Hoenn bloomed in crisp 4K, every blade of grass and flash of lightning rendered with a clarity the original creators could only have dreamed of.
Leo smiled. The "aes-keys.txt" wasn't just a file anymore. It was a bridge between the childhood he remembered and the technology he loved today. He picked up his controller, ready to start a journey he’d finished a dozen times before, but one that felt brand new all over again. 🔑 Understanding aes-keys.txt in Citra

The neon glow of Leo’s dual monitors was the only light in his cramped apartment, a digital sanctuary where the hum of cooling fans replaced the city's noise. For three days, he had been wrestling with a ghost: an encrypted .3ds file of a long-lost prototype he’d found on an obscure forum. It was the "Holy Grail" of his collection, but every time he tried to boot it in Citra, the screen remained a mocking, stubborn black.
The error was always the same: “Your ROM is encrypted. Please provide the AES keys.”
Leo knew the drill. Most users just dumped their keys from a physical 3ds console using GodMode9, but this prototype was different. It used a unique, non-standard encryption—a digital lock that shouldn't exist. He had spent hours scouring the Citra Community Forums and deep-diving into the Hacks Guide Wiki for a lead.
Finally, at 3:00 AM, he found a buried post from a user named 0xShadow. It contained nothing but a string of hex code and a single instruction: "Place in aes-keys.txt. Good luck, Traveler."
With trembling fingers, Leo opened his Citra user folder. He navigated past the sysdata and config folders, right-clicked, and created a new document: aes-keys.txt. He pasted the string, saved it, and held his breath.
He dragged the game file over the Citra icon. The emulator’s log window scrolled frantically—thousands of lines of code decrypting in real-time. Then, the black screen flickered. A familiar chiptune melody, slightly distorted and eerie, filled the room. The title screen appeared, but the characters weren't from any game he recognized. They were silhouettes, their eyes glowing with the same neon blue as his monitors.
Leo reached for his controller, but his hand stopped. On the second screen of the emulator, a line of text appeared that wasn't part of the game: "Thanks for the key, Leo. We’ve been waiting to get out."
The aes-keys.txt file on his desktop suddenly vanished. Outside his window, the streetlights began to flicker in sync with the chiptune beat. Leo realized too late that some keys aren't meant to unlock games; they're meant to unlock doors.
Citra and AES Keys
Citra uses AES (Advanced Encryption Standard) keys to decrypt and encrypt 3DS game files. These keys are usually stored in a file named aes-keys.txt. The keys in this file are crucial for Citra to function correctly, as they allow the emulator to access and process encrypted data.
Obtaining AES Keys
To use Citra, you'll need to obtain the AES keys. However, due to copyright and legal issues, these keys cannot be distributed directly. You might need to extract them from your own 3DS console or find a reliable source that provides guidance on how to obtain them.
Configuration and Usage
Here's a general outline of how to configure Citra with your AES keys:
