Pablo Curiel f79680184d Runtime key derivation with hardcoded key sources 
* aes: add aes128EcbCrypt() as a one-shot function to perform AES-128-ECB crypto. The rest of the codebase now calls this function whenever suitable.

* fs_ext: add const keyword to IPC input structs wherever suitable.

* key_sources: add hardcoded master key vectors (prod, dev); master KEK sources (Erista, Mariko); master key source; ticket common key source; SMC key type sources; SMC seal key masks; AES key generation source; NCA header KEK source; NCA header key source and NCA KAEK sources. Also fixed the hardcoded gamecard CardInfo key source for dev units (it was previously generated using retail keydata, my bad).

* keys: remove keysGetNcaMainSignatureModulus(); remove keysDecryptNcaKeyAreaEntry(); repurpose keyset struct to only hold keys that can actually be used for the current hardware type; remove KeysGameCardKeyset; remove keysIsXXModulusYYMandatory() helpers; remove keysRetrieveKeysFromProgramMemory(); remove keysDeriveSealedNcaKeyAreaEncryptionKeys(); add keysDeriveMasterKeys() and keysDerivePerGenerationKeys(); rename keysDeriveGameCardKeys() -> keysDeriveGcCardInfoKey(); add small reimplementations of GenerateAesKek, LoadAesKey and GenerateAesKey; add keysLoadAesKeyFromAesKek() and keysGenerateAesKeyFromAesKek() wrappers. Furthermore, master key derivation is now carried out manually using hardcoded key sources and the last known master key, which is loaded from the Lockpick_RCM keys file -- if the last known master key is unavailable, the key derivation algorithm will then fallback to TSEC root key / Mariko KEK based key derivation, depending on the hardware type.

* nca: add hardcoded NCA man signature moduli (prod, dev); merge ncaDecryptKeyArea() and ncaEncryptKeyArea() into ncaKeyAreaCrypt().

* nxdt_utils: add utilsIsMarikoUnit(); remove _utilsAppletModeCheck(); rename utilsAppletModeCheck() -> utilsIsAppletMode().

* services: remove spl:mig dependency (yay).

* smc: add SmcKeyType enum; add SmcSealKey enum; add SmcGenerateAesKekOption struct; add smcPrepareGenerateAesKekOption().

nxdumptool

Nintendo Switch Dump Tool

Official Discord server: https://discord.gg/SCbbcQx

This branch is used for the development of the ongoing nxdumptool rewrite. Code is highly experimental and lacks a proper UI at this time, but it has been thoroughly tested and should be safe to use. Proof-of-concept (PoC) builds are provided to test different aspects of the codebase.

If a nxdumptool build from the releases page isn't working for whatever you're trying to do (e.g. RomFS dumping), odds are it will work with a PoC build from this particular branch. The old branch will not receive any further updates.

A GitHub workflow is used to automatically build each new commit -- feel free to check it out.

This readme will be updated whenever the rewrite branch is ready for a proper release.

Currently planned changes for this branch include:

  • USB ABI (dump data directly to a PC). ✅
  • USB Mass Storage device support (FAT, NTFS, EXT). ✅
  • Gamecard header dumps. ✅
  • Gamecard CardInfo area dumps. ✅
  • Gamecard InitialData area dumps. ✅
  • Individual NCA dumps (select and dump a specific NCA from a title). ✅
  • Individual NCA FS section dumps (select and dump a specific FS section from a specific NCA belonging to a title, in both extracted and raw image forms) (this includes patched RomFS images). ✅
  • System title support (e.g. dump qlaunch, shared fonts and much, much more at runtime). ✅
  • Better support for NCA BucketTree storages (Indirect, AesCtrEx, Sparse, Compressed), as well as better handling of multi-layered reads in combination with game updates. ✅
  • Volatile ticket dumping -- temporary tickets that are downloaded and kept in RAM instead of being written to the eMMC. ✅
  • Better memory handling while dealing with compressed NRO binaries. ✅
  • Event-driven background threads to manage gamecard insertions/ejections, gamecard application metadata parsing (e.g. the game would be properly identified even if its gamecard has never been used on your console), USB ABI sessions and USB Mass Storage devices. ✅
  • Improved support for multigame gamecards and titles with more than one Program NCA (e.g. SM3DAS). ✅
  • Control.nacp patching while dumping NSPs (lets you patch screenshot, video, user account and HDCP restrictions). ✅
  • Full system update dumps. ❌
  • New UI using a customized borealis fork. ⚠️

  • ✅ - Implemented
  • ⚠️ - Partially implemented
  • ❌ - Not implemented
