Homebrew Batch CIA 3DS Decryptor - A simple batch file to decrypt CIA & 3DS

[stockerzz]

Is this compatible with windows 10? Whenever I try to decrypt my Pokemon moon file and click decrypt it does it immediately and doesn’t make new files. I’ve heard you have to rename the file to a set of 3 letters before the .cia file or if it decrypts immediately without actually doing anything it’s because the software isn’t compatible with your system. Thoughts? Thanks.

If anyone came here looking for a straight encrypted game CIA -> decrypted game CIA solution,
simply remove or comment out the lines 64-69 in the batch file and, optionally, rename "-decfirst.cia" to "-decrypted.cia" on the line 41.
Better save it as a separate batch ofc.

...I don't think I can thank you and OP enough for this, so as an expression of gratitude, I shall let thee behold a Carbuncle.

Everytime i want to decrypt a cia game, it always end up freezing my laptop mid way and when the freeze is done, it will say that it's finished, but when i tried to run the file on citra, the file is still encrypted, my laptop is compatible and i dont know why this happens

To anyone getting the 'running the batch goes directly to finish with no new file generated' - try dragging the CIA file to decrypt.exe (just clicking decrypt.exe does not work, you have to give it a file to chew on) and it should run through and generate a bunch on NCCH files. Then double click on the .bat and it will run through and generate a decrypted CIA/CCI.
Make sure everything is in the same folder.

where do i find this batch file? all i have is the .cia and when trying to decrypt citra keeps saying it isn't i don't understand what lines or batch file this is refencing

This is a bit of an edge case, but just in case people don't know: the program won't work if your .cia file has an exclamation mark (and potentially other forms of punctuation). So maybe just edit the filename to omit the exclamation mark.

that does not work for me.... can you help me?

hey, i get following error message when trying to use it:

[TIK WARNING] Failed to sign header
[TMD WARNING] Failed to sign header

am I the only one with that problem and is there a way i can fix it?
cheers

edit: trying over and over again somehow worked for me. problem got fixed

Im getting the same error but after trying again several times there has been no change.

 

[maxmaxmax]

thats works for .3ds files but not cia...

 

[stronzium]

the decrypter wont work to me
it creates lots of .cci that doesnt get away after finishing the process, none of these works with citra and the main .cia remaines crypted, back to square one, im pretty outta nervs

 

[AnIdiotWaffle]

Do I have to have a folder for the source code? (I would assume yes) But if I do, where do I put it and do I have to name it a specific thing?

 

[TacticalVictory]

I have tried renaming the .3ds file I am trying to decrypt, Battleship, but still get the instant Finished message. Any way to to stop this?

Why is everything restricted to the "new" 3DS only? All it is is just the 3DS with a built-in amiibo reader.

Because the New 3DS also has better and beefier hardware, not just a amiibo reader.

It has a source code version, written in python. You can get it by searching decrypt_v2.zip on Google.

I Couldn't find anything

Could we get source code for decrypt.exe? Not everyone runs windows.

there is a thing that says ntrboot_flasher under the "Could we get source code for decrypt.exe? Not everyone runs windows." part of the post, why the hell is that there
