# NXTools
# NNTools
Tools & Libraries for NX (Nintendo Switch).
Tools & Libraries for Nintendo devices.
[![License](https://img.shields.io/badge/license-MIT-blue.svg)](/LICENSE)
# Tools
* __nstool__ - read *.npdm, read/extract PartitionFS (PFS0|HFS0) blobs (including *.nsp), read/extract RomFS blobs, read/extract *.xci, read/extract *.nca, read *.cnmt, read *.nso, read *.nro, read *.nacp
* [__nstool__](/programs/nstool/README.md) - General purpose reading/extraction tool for Nintendo Switch file formats.
# Libraries
* __libfnd__ - Foundation library.
* __libcrypto__ - Cryptographic functions (AES,SHA,RSA). Wrapper for [mbedTLS](https://github.com/ARMmbed/mbedtls)
* __libcompress__ - Compression algorithms (LZ4). Wrapper for [lz4](https://github.com/lz4/lz4)
* __libpki__ - Processes Nintendo's proprietary PKI.
* __libes__ - Processes Nintendo's eShop file types.
* __libnx__ - Processes NX file types.
* __libnx-hb__ - Processes NX file types (homebrew extensions).
* __libhac__ - Processes Nintendo Switch file types.
* __libhac-hb__ - Processes Nintendo Switch file types (homebrew extensions).
# Building
On MacOS/Linux/WSL run `make`.
For Windows, Visual Studio 2017 is supported.
# External Keys
Programs/libraries don't embed any keys that are copyright protected. However keys can be imported via a keyset file.
For programs that support it, the keyset file can be provided via the command line (see program usage for details). Alternatively a keyset file located in ___$HOME/.switch/prod.keys___ (or ___$HOME/.switch/dev.keys___ for dev) will be imported automatically if one is not provided at the command line.
Keyset files are ASCII text files containing one key per line, in the form "__key_name = HEXADECIMALKEY__". Case and whitespace do not matter, ';' character can be used to insert comments.
See [KEYS.md](/KEYS.md) for more details.

# Loading keyset files automatically
If a keyset file is located in ___$HOME/.switch/___ it will be loaded automatically.
# General Keys (prod.keys and dev.keys)
Some switch files formats feature encryption and or cryptographic signatures. In order to process these file formats, some keys are required. These keys can be supplied via a keyfile: ___prod.keys___ (or ___dev.keys___ for devkit variants).
This keyset file can be provided via the command line (refer to usage for details).

# Compatibility with hactool keyset files
NXTools keyset files share the same keyset file format as [hactool](https://github.com/SciresM/hactool/blob/master/KEYS.md), but names of keys may differ. For compatibility, hactool names for equivalent keys are accepted.
