Lockpick

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.
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.
What this software does differently
=
* Dumps titlekeys
* Dumps `titlekeys`
* Dumps `6.2.0` keys
* 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)
Usage
=
1. Use [Hekate](https://github.com/CTCaer/hekate/releases) to dump TSEC and fuses:
1. Use [Hekate v4.5+](https://github.com/CTCaer/hekate/releases) to dump TSEC and fuses:
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...`
3. Select `Print fuse info`
4. Press `Power` to save fuses to SD card
4. Press `Power` to save fuse info to SD card
5. Select `Print TSEC keys`
6. Press `Power` to save TSEC to SD card
6. Press `Power` to save TSEC keys to SD card
2. Launch CFW of choice
3. Open `Homebrew Menu`
4. Run `Lockpick`
5. Use the resulting `prod.keys` file as needed and rename if required
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)
Building
=
Release built with `libnx v1.6.0`.
