Lockpick_RCM payload - Official Thread


Description

Lockpick_RCM is a bare metal Nintendo Switch payload that derives encryption keys for use in Switch file handling software like hactool, hactoolnet/LibHac, ChoiDujour, etc. without booting Horizon OS.

Source: https://github.com/shchmue/Lockpick_RCM
Payload: https://github.com/shchmue/Lockpick_RCM/releases

Due to changes imposed by firmware 7.0.0, Lockpick homebrew can no longer derive the latest keys. In the boot-time environment however, there are fewer limitations. That means the new keys are finally easy to dump!

Usage
  • Launch Lockpick_RCM.bin using your favorite payload injector or chainload from Hekate by placing it in /bootloader/payloads
  • Upon completion, keys will be saved to /switch/prod.keys on SD
  • If the console has Firmware 7.x, the /sept/ folder from Atmosphère or Kosmos release zip containing both sept-primary.bin and sept-secondary.enc must be present on SD or else only keyblob master key derivation is possible (ie. up to master_key_05 only)
Big thanks to CTCaer
For Hekate and all the advice while developing this!

Known Issues
  • Chainloading from SX will hang immediately due to quirks in their hwinit code, please launch payload directly

Haven't tinkered with my Switch for a while, but tried using this tool to get my keys, but all I get when I inject it is a black screen.

I'm on 6.0.0 and AMS 0.9.2
Which version do you use? Try the normal lockpick. Lockpick RCM is only required for FW 7.0 and above.

Okay!

I just tried using the regular Lockpick, and it seemed to work fine, but the keys generated don't seem to have worked. I tried using them for Switch Army Knife and got an error message asking if the keys were right.

the latest Lockpick_RCM doesn't work? that's odd. you might need to update that extremely old version of atmosphere (it's a year and a half old, latest is 2 weeks old), but indeed you're not going to get any more recent keys unless you update your firmware, so that's why SAK is likely having trouble with whatever content you're using it on. I'd suggest making sure Lockpick_RCM, Atmosphere, and your console's firmware are all up to date and trying again (update Atmosphere first or you won't be able to boot new firmware in CFW). Use either Daybreak or normal settings menu to update firmware.
 
Any word on when lockpick will be able to dump v11? Thank you for all you do Shchmue

I appreciate the work you do! Is there any word on when Lockpick will support v11? I get errors anytime I try to dump my SysMMC keys.

Thanks!
