Pablo Curiel c1b76fb2d9 Rework signature/cert/tik interfaces. 
* signature: add comments to SignatureType enum entries about the exact signing algorithms and padding schemes used.
* signature: rename signatureGetSigType() -> signatureGetTypeFromSignedBlob().
* signature: rename signatureIsValidSigType() -> signatureIsValidType().
* signature: rename signatureGetSigSize() -> signatureGetSigSizeByType().
* signature: rename signatureGetBlockSize() -> signatureGetBlockSizeByType().
* signature: rename signatureGetSig() -> signatureGetSigFromSignedBlob().
* signature: rename signatureGetPayload() -> signatureGetPayloadFromSignedBlob().
* signature: add signatureGetBlockSizeFromSignedBlob().

* cert: add more comments to the code.
* cert: update code to match signature interface changes.
* cert: add CERT_RSA_PUB_EXP_SIZE macro.
* cert: change public_exponent field in CertPublicKeyBlockRsa* structs from u32 to u8 array.
* cert: add size field to CertificateChain struct.
* cert: rename certGetCommonBlock() -> certGetCommonBlockFromSignedCertBlob.
* cert: rename certGetPublicKeySize() -> certGetPublicKeySizeByType().
* cert: rename certGetPublicKeyBlockSize() -> certGetPublicKeyBlockSizeByType().
* cert: rename certIsValidCertificate() -> certIsValidSignedCertBlob().
* cert: rename certGetSignedCertificateSize() -> certGetSignedCertBlobSize().
* cert: rename certGetSignedCertificateHashAreaSize() -> certGetSignedCertBlobHashAreaSize().
* cert: remove certGetPublicKey(), certGetPublicExponent() and certCalculateRawCertificateChainSize().
* cert: add certGetPublicKeyTypeFromCommonBlock(), certGetPublicKeyTypeFromSignedCertBlob(), certGetPublicKeySizeFromSignedCertBlob(), certGetPublicKeyBlockSizeFromSignedCertBlob(), certGetPublicKeyFromSignedCertBlob(), certGetPublicExponentFromSignedCertBlob(), certIsValidCertificate() (w/diff func sig), certGetCommonBlockFromCertificate(), certGetPublicKeyTypeFromCertificate(), certGetPublicKeySizeFromCertificate(), certGetPublicKeyBlockSizeFromCertificate(), certGetPublicKeyFromCertificate(), certGetPublicExponentFromCertificate() and certGetHashAreaSizeFromCertificate() functions.
* cert: avoid byteswapping the public key type value in multiple places -- it is now only being done in certGetPublicKeyTypeFromCommonBlock().
* cert: call certFreeCertificateChain() in _certRetrieveCertificateChainBySignatureIssuer() before attempting to retrieve the certificate chain.
* cert: other minor changes and corrections.

* tik: update code to match signature interface changes.
* tik: add missing comments to TikPropertyMask enum entries.
* tik: add key_generation, enc_titlekey_str and dec_titlekey_str fields to Ticket struct.
* tik: update tikRetrieveTicketByRightsId() to also take in a key_generation argument, instead of getting it from the rights ID (which could fail if it's using a key generation lower than HOS 3.0.1) or the key_generation field from the common ticket block (which could fail if the ticket has been tampered by certain tools).
* tik: rename tikGetCommonBlock() -> tikGetCommonBlockFromSignedTicketBlob().
* tik: change function signature for tikGetTicketSectionRecordsBlockSize().
* tik: rename tikIsValidTicket() -> tikIsValidSignedTicketBlob().
* tik: rename tikGetSignedTicketSize() -> tikGetSignedTicketBlobSize().
* tik: rename tikGetSignedTicketHashAreaSize() -> tikGetSignedTicketBlobHashAreaSize().
* tik: rename tikGetEncryptedTitleKeyFromTicket() -> tikGetEncryptedTitleKey().
* tik: add tikIsValidTicket() (w/diff func sig), tikGetCommonBlockFromTicket(), tikGetHashAreaSizeFromTicket(), tikFixTamperedCommonTicket(), tikVerifyRsa2048Sha256Signature() and tikDecryptVolatileTicket() functions. Ticket signature verification is only carried out for common tickets in tikFixTamperedCommonTicket().
* tik: change argument order in tikGetTicketEntryOffsetFromTicketList() and tikRetrieveTicketEntryFromTicketBin().
* tik: add TIK_COMMON_CERT_NAME and TIK_DEV_CERT_ISSUER macros.
* tik: use a scoped lock when calling tikRetrieveTicketFromEsSaveDataByRightsId().
* tik: simplify certificate chain retrieval steps in tikConvertPersonalizedTicketToCommonTicket() by always using the XS00000020 certificate.
* tik: wipe license_type and property_mask fields in tikConvertPersonalizedTicketToCommonTicket().
* tik: other minor changes and corrections.

Other changes include:

* keys: fix key generation checks in keysGetNcaKeyAreaKeyEncryptionKey() and keysGetTicketCommonKey().

* rsa: move core logic from rsa2048VerifySha256BasedPssSignature() into a new function: rsa2048VerifySha256BasedSignature().
* rsa: add rsa2048VerifySha256BasedPkcs1v15Signature() function.

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. ⚠️

Legend:

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