# 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).

|
## 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.
