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

So I dumped my keys and got a prod.keys, title.keys, and dev.keys. However, the application XCI_NCA_NSP_v2 asks for a Keys.dat? What exactly is that file?

EDIT: Never mind, figured out I can just make a copy of my prod.keys and rename the copy to keys.dat.

Does this need an update again for 13.1.0 for games like animal crossings new update? I know I couldn't dump the latest update with NXDumpTool and unsure the issue. It mentioned using lockpick_rcm which I did.
