This is a ground-up C++17 rewrite of homebrew key derivation software, namely [kezplez-nx](https://github.com/tesnos/kezplez-nx). It also dumps titlekeys. This will dump all keys through `*_key_05` on firmwares below `6.2.0` and through `*_key_06` on `6.2.0` and above.
* Uses the superfast `xxHash` instead of `sha256` when searching exefs for keys for a ~5x speed improvement
* Gets all possible keys from running process memory - this means no need to decrypt `Package2` at all, let alone decompress `KIP`s
* Gets `header_key` without `tsec`, `sbk`, `master_key_00` or `aes` sources - which may or may not be the same way `ChoiDujourNX` does it :eyes: (and I'm gonna issue a challenge to homebrew title installers to implement similar code so you don't need your users to use separate software like this :stuck_out_tongue_winking_eye: it's up to you to figure out if the same can be done for `key_area_keys` if needed)
1. Push hekate payload bin using [TegraRCMSmash](https://github.com/rajkosto/TegraRcmSmash)/[TegraRCMGUI](https://github.com/eliboa/TegraRcmGUI)/modchip/injector
2. Using the `VOL` and `Power` buttons to navigate, select `Console info...`
You may instead use [biskeydump](https://github.com/rajkosto/biskeydump) and dump to SD to get all keys prior to the 6.2.0 generation - all keys up to those ending in 05. This will dump all keys up to that point regardless which firmware it's run on.
Notes
=
* To get keys ending in 06, you must have firmware `6.2.0` installed
* No one knows `package1_key_06`, it's derived and erased fully within the encrypted TSEC payload. While there's a way to extricate `tsec_root_key` due to the way it's used, this is unfortunately not true of the `package1` key
* If for some reason you dump TSEC keys on `6.2.0` and not fuses (`secure_boot_key`) you will still get everything except any of the `package1` or keyblob keys (without `secure_boot_key`, you can't decrypt keyblobs and that's where `package1` keys live)
Uses `freetype` which comes with `switch-portlibs` via `devkitPro pacman`:
```
pacman -S libnx switch-portlibs
```
then run:
```
make
```
to build.
Special Thanks
=
* tèsnos! For making [kezplez-nx](https://github.com/tesnos/kezplez-nx), being an all-around cool and helpful person and open to my contributions, not to mention patient with my *enthusiasm*. kezplez taught me an absolute TON about homebrew.
* SciresM for [hactool](https://github.com/SciresM/hactool), containing to my knowledge the first public key derivation *software*, and for `get_titlekeys.py`
* roblabla for the original keys [gist](https://gist.github.com/roblabla/d8358ab058bbe3b00614740dcba4f208) and for believing in our habilities
* The folks in the [ReSwitched](https://reswitched.team/) Discord server for answering my innumerable questions while researching this (and having such a useful chat backlog!)
* The memory reading code from jakibaki's [sys-netcheat](https://github.com/jakibaki/sys-netcheat) was super useful for getting keys out of running process memory
* The System Save dumping methodology from Adubbz' [Compelled Disclosure](https://github.com/Adubbz/Compelled-Disclosure)
* Shouts out to fellow key derivers: shadowninja108 for [HACGUI](https://github.com/shadowninja108/HACGUI), Thealexblarney for [Libhac](https://github.com/Thealexbarney/LibHac), and [rajkosto](https://github.com/rajkosto/) :eyes:
* The constantly-improving docs on [Switchbrew wiki](https://switchbrew.org/wiki/) and [libnx](https://switchbrew.github.io/libnx/files.html)
* Literally the friends I made along the way! I came to the scene late and I've still managed to meet some wonderful people :) Thanks for all the help testing, making suggestions, and cheerleading!
