# libhac
|
||
|
|
|
||
|
|
libhac is a .NET or .NET Core library for opening, decrypting and extracting common content file formats used by the Nintendo Switch.
|
||
|
|
|
||
|
|
All content is imported and exported as .NET streams. This means that reading nested file types and encryptions can easily be done by linking different file readers together.
|
||
|
|
For example, the files from a title stored on the external SD card can be read or extracted in this way.
|
||
|
|
`NAX0 Reader` -> `NCA Reader` -> `RomFS Reader` -> `Individual Files`

|
||
|
|
|
||
|
|
hactoolnet is an example program that uses libhac. It is used in a similar manner to [hactool](https://github.com/SciresM/hactool).
|
||
|
|
|
||
|
|
## Usage
|
||
|
|
```
|
||
|
|
Usage: hactoolnet [options...] <path>
|
||
|
|
Options:
|
||
|
|
-r, --raw Keep raw data, don't unpack.
|
||
|
|
-y, --verify Verify hashes.
|
||
|
|
-k, --keyset Load keys from an external file.
|
||
|
|
-t, --intype=type Specify input file type [nca, switchfs]
|
||
|
|
--titlekeys <file> Load title keys from an external file.
|
||
|
|
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.
|
||
|
|
--listromfs List files in RomFS.
|
||
|
|
--basenca Set Base NCA to use with update partitions.
|
||
|
|
Switch FS options:
|
||
|
|
--sdseed <seed> Set console unique seed for SD card NAX0 encryption.
|
||
|
|
--listapps List application info.
|
||
|
|
--listtitles List title info for all titles.
|
||
|
|
--title <title id> Specify title ID to use.
|
||
|
|
--outdir <dir> Specify directory path to save title to.
|
||
|
|
--romfsdir <dir> Specify RomFS directory path.
|
||
|
|
```
|
||
|
|
|
||
|
|
## Examples
|
||
|
|
|
||
|
|
#### List applications on a Switch SD card or NAND
|
||
|
|
`hactoolnet -t switchfs --sdseed <sd_seed> --listapps <sd_root_path>`
|
||
|
|
|
||
|
|
#### Extract a title from an SD card or NAND as NCA files
|
||
|
|
`hactoolnet -t switchfs --sdseed <sd_seed> --title <title_id> --outdir output <sd_root_path>`
|
||
|
|
|
||
|
|
#### Extract the RomFS from a title from an SD card or NAND
|
||
|
|
`hactoolnet -t switchfs --sdseed <sd_seed> --title <title_id> --romfsdir romfs <sd_root_path>`
|
||
|
|
|
||
|
|
Specifying the base title ID will extract the unpatched title.
|
||
|
|
Specifying the patch title ID will extract the patched title.

|
## External Keys
|
||
|
|
|
||
|
|
Keys can be loaded from a text file by specifying a filename with the `-k` argument. The file should be in the same format read by [hactool](https://github.com/SciresM/hactool#external-keys):
|
||
|
|
"Keyset files are text files containing one key per line, in the form "key_name = HEXADECIMALKEY". Case shouldn't matter, nor should whitespace."
|
||
|
|
|
||
|
|
Title keys can be loaded from a text file by specifying a filename with the `--titlekeys` argument. The file should contain one key per line in the form `rights_id,HEXADECIMALKEY`.
|
||
|
|
|
||
|
|
If a keyfile is not set at the command line, hactoolnet will search for and load keyfiles in `$HOME/.switch/prod.keys` and `$HOME/.switch/titlekeys.txt`.
