# hactool
|
|
|
|
|
|
|
|
hactool is a tool to view information about, decrypt, and extract common file formats for the Nintendo Switch, especially 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.
|
|
|
|
If on Windows, I recommend using MinGW.
|
|
|
|
## External Keys
|
|
|
|
External keys can be provided by the -k/--keyset argument to the a keyset filename.
|
|
Keyset files are text files containing one key per line, in the form "key_name = HEXADECIMALKEY".
|
|
Case shouldn't matter, nor should whitespace.
|
|
|
|
In addition, if -k/--keyset is not set, hactool will check for the presence of a keyset file
|
|
in $HOME/.switch/prod.keys (or $HOME/.switch/dev.keys if -d/--dev is set). If present, this file
|
|
will automatically be loaded.
