Ensure your complete directory structure looks exactly like this:
If Citra still displays an encryption error after you added the keys, check the following:
tries to mimic a real 3DS system environment but cannot legally ship with Nintendo's proprietary decryption keys.
A standard installation of Citra searches the global system directory for decryption keys. Citra Portable, by design, is isolated from the host computer's operating system. It cannot access global system folders, meaning you must manually place the aes_keys.txt file directly inside its portable file structure to boot encrypted games.

There are two main ways to get your keys. The first is highly recommended for accuracy; the second is for advanced users comfortable with manual configuration.
This is a very common user error. The issue is almost always one of two things:
I can provide the exact path for your operating system if you let me know! Ensure your complete directory structure looks exactly like
This is where your text file comes in. When placed correctly, this file provides the emulator with a library of the necessary cryptographic keys. The text file lists each key with a specific label, like "slot0x25KeyX", followed by the actual 32-digit hexadecimal key value, such as slot0x25KeyX=0123456789ABCDEF0123456789ABCDEF . With the keys at its disposal, Citra can decrypt the game's data on the fly, allowing it to load and play it as if it were running on a real 3DS system.
Alternatively, some users avoid using aes_keys.txt entirely by using ROMs, which have already had their encryption removed and can be played directly by Citra without additional key files. 3DS trying to get AES keys : r/Roms
Once the emulator detects the local user folder, it mirrors the standard operating system directories locally. You must create the correct directory path manually to hold your keys. Open your newly created folder. Inside it, create a new subfolder named sysdata . It cannot access global system folders, meaning you
If you launch a game and receive an error regarding encryption, it means Citra cannot find the file or the keys inside are incorrect.
The required file is typically found on the SD card after running a "DumpKeys" script, resulting in sdmc:/gm9/aes_keys.txt . 5. Troubleshooting
: When Citra detects this folder upon launch, it will redirect all its data—including system keys and save files—to this local directory instead of the system's default path. Understanding the aes_keys.txt File
: Run your exact setup straight from a flash drive, external hard drive, or cloud storage sync folder on any PC.
