- Mixed folders or inputs are also accepted, you can decrypt or encrypt multiple files, regardless of their type. This being said, you can only do encrypt _OR_ decrypt at one time.

- Required files will automatically be searched for in the application runtime directory as well as `%HOME%/.config/ndecrypt`, also known as `%USERPROFILE%\.config\ndecrypt` on Windows.

There are 3 major files that you can use to give NDecrypt that extra _oomph_ of functionality that it really needs. That is, you can't do any encryption or decryption without at least one of these present. I can't give you the files and I can't generate them for you on the fly with the correct values. Keys are a thorny thing and I just do not want to deal with them. Values are validated, at least, but you'll only get yelled at on run if one of them is wrong.

**Note:** The `NitroEncryptionData` field is also known as the "Blowfish table" for Nintendo DS carts. It's stored in the same hex string format as the other keys. There's some complicated stuff about how it's used and where it's stored, but all you need to know is that it wasn't required for `keys.bin` and `aes_keys.txt` but will be for `config.json`.

**Community Note:** If you have used previous versions of NDecrypt and already have either `keys.bin` or `aes_keys.txt`, consider using [this helpful community-made script](https://gist.github.com/Dimensional/82f212a0b35bcf9caaa2bc9a70b3a92a) to make your life a bit easier. It will convert them into the new `config.json` format that will be supported from here on out.

### `config.json`
|
||||
|
||||
The up-and-coming, shiny, new, exciting, JSON-based format for storing the encryption keys that you need for Nintendo DS, 3DS, and New 3DS. This JSON file is not generated by anything, but maps pretty much one-to-one with the code inside of NDecrypt, making it super convenient to use. Keys provided need to be hex strings (e.g. `"AABBCCDD"`). Any keys that are left with `null` or `""` as the value will be ignored. See [the sample config](https://github.com/SabreTools/NDecrypt/blob/master/config-default.json) that I've nicely generated for you. You're welcome.

This is used if it's found, even if you have a `keys.bin` file or if you're using the `-a` flag. It's intentionally very bullish about being used because this will be the singular format for keys in the future. I know I mentioned this above as well, but I also know users don't like reading.
|
||||
|
||||
In the future, this file will be automatically generated on first run along with some cutesy little message telling you to fill it out when you get a chance. It's not doing it right now because I don't want to confuse users. Including those reading this. How meta.

This is the OG of NDecrypt key file formats. It's a weird, binary blob of a format that is composed of little-endian values (most common extraction methods produce big endian, so keep that in mind). It's only compatible wtih Nintendo 3DS and New 3DS keys and is incredibly inflexible in its layout. The little-endianness of it is a relic of how keys were handled in-code previously and I really can't fix it now. If you don't have a key, it needs to be filled with `0x00` bytes so it doesn't mess up the read. Yeah.

Oddly, this gets confused with some similar format that GodMode9 works with, but it has nothing to do with it. If you try to use one of those files in place of this one, something will probably break. It wasn't intentional, I just didn't look ahead of time. See the table in the main part of this section for the order the keys need to be stored in.

### `aes_keys.txt`

### `aes_keys.txt` (Deprecated)

This is an INI-based format that was super popular among 3DS emulators and probably still is. To use this over `keys.bin`, the `-a` flag has to be included or else it won't be found. Yes, even if `keys.bin` isn't even in the folder. Weird thing, I know, but just roll with it please. The one major downside to this is that development keys can't be defined in this format. If you forget this and use `-d` anyway, NDecrypt will disable that flag for you. You're welcome.
