# ncatool
|
||||
|
||||
|
||||
|
||||
ncatool is a tool to view information about, decrypt, and extract Nintendo Content Archives.
|
||||
|
||||
It is heavily inspired by [ctrtool](https://github.com/profi200/Project_CTR/tree/master/ctrtool).
|
||||
|
||||
## Usage
|
||||
|
||||
```
|
||||
Usage: ncatool [options...] <file>
|
||||
Options:
|
||||
-i, --info Show file info.
|
||||
This is the default action.
|
||||
-x, --extract Extract data from file.
|
||||
This is also the default action.
|
||||
-r, --raw Keep raw data, don't unpack.
|
||||
-y, --verify Verify hashes and signatures.
|
||||
-d, --dev Decrypt with development keys instead of retail.
|
||||
--titlekey=key Set title key for Rights ID crypto titles.
|
||||
--contentkey=key Set raw key for NCA body decryption.
|
||||
NCA options:
|
||||
--section0=file Specify Section 0 file path.
|
||||
--section1=file Specify Section 1 file path.
|
||||
--section2=file Specify Section 2 file path.
|
||||
--section3=file Specify Section 3 file path.
|
||||
--section0dir=dir Specify Section 0 directory path.
|
||||
--section1dir=dir Specify Section 1 directory path.
|
||||
--section2dir=dir Specify Section 2 directory path.
|
||||
--section3dir=dir Specify Section 3 directory path.
|
||||
--exefs=file Specify ExeFS file path. Overrides appropriate section file path.
|
||||
--exefsdir=dir Specify ExeFS directory path. Overrides appropriate section directory path.
|
||||
--romfs=file Specify RomFS file path. Overrides appropriate section file path.
|
||||
--romfsdir=dir Specify RomFS directory path. Overrides appropriate section directory path.
|
||||
--listromfs List files in RomFS.
|
||||
```
|
||||
|
||||
## Building
|
||||
|
||||
Copy `config.mk.template` to `config.mk`, make changes as required, and then run `make`.
|
||||
If your `make` is not GNU make (e.g. on BSD variants), you need to call `gmake` instead.
|
||||
|
||||
To build under windows, you will need to build [libgpgerror](https://www.gnupg.org/(fr)/related_software/libgpg-error/index.html), and [libgcrypt](https://www.gnu.org/software/libgcrypt/).
|
||||
You may need [libiconv](https://www.gnu.org/software/libiconv/) when not building on Linux.
|
||||
Fairly recent versions (~1.8.0) are required of the libraries in order to support AES-XTS operations. I recommend using MinGW.
|
||||

||||
