3ds Aeskeystxt Work

With ctrtool:

ctrtool --content=0 my.cia --keyfile=aes_keys.txt

With 3dstool:

3dstool -x -t cxi --header ncch_header.bin --plain plain.bin -k aes_keys.txt

aeskeystxt (often named aes_keys.txt) is a plaintext file used by various 3DS decryption tools (like citra, godmode9, 3dstool, ctrtool, lotus3ds, etc.) to store hardware-specific cryptographic keys for the 3DS’s AES engine. 3ds aeskeystxt work

Do not trust random Google Drive links. The safest method is to dump keys from your own 3DS console (if you have custom firmware – Luma3DS). With ctrtool : ctrtool --content=0 my

Using GodMode9 (Recommended):

This method guarantees your aeskeys.txt works for your console region and version. With 3dstool : 3dstool -x -t cxi --header ncch_header

You do not need to wait for a decryption failure. Here is a quick test.
