* keysGetKeyAndValueFromFile() is now thread-safe -- may be useful for people reusing code from nxdumptool. The dynamic buffer allocated by __getline() must be freed by the caller. Furthermore, this fixes an out-of-bounds issue while writing data to the static array that was being used with fgets().
* Empty lines are now considered failures.
* keysGetKeyAndValueFromFile() now validates the value string and converts it to lowercase as well.
* Adjusted the example regex in the description for keysGetKeyAndValueFromFile() to accurately match what the function actually does.
* Added helper macros to keysReadKeysFromFile().
* Thread-safe.
* Provides getter/setter functions for the data types used by nxdumptool's configuration.
* Each setter function writes the modified JSON configuration back to the SD card.
* Configuration is validated on interface initialization. If validation fails, a default JSON template is loaded from the application's RomFS and written back to the SD card.
Other changes:
* Implement directory creation.
* Moved more preprocessor definitions to defines.h.
* Replaced strtok() calls throughout the code with strtok_r() to guarantee thread-safety.
* Added custom key sources to derive CardInfo keys at runtime using SPL.
* Implemented CardInfo area decryption.
* Implemented LAFW blob lookup in FS .data segment to retrieve the current LAFW version.
P.S.: still need to move around code to perform the LAFW version check at the places we need. But the current code is good enough for a test.
* Implemented RSA-2048-PSS + SHA256 signature verification.
* Refactored RSA-2048-OAEP decryption steps to use mbedtls function calls.
* Implemented NCA header main signature verification.
* Replaced Björn Samuelsson's CRC32 algorithm with the hardware accelerated CRC32 checksum calculation from libnx (latest commit with support for calculation in blocks).
* Rewrote mutex handling throughout the code to use a small, macro-based scoped lock implementation.
* Removed extern variables from common.h - launch path management is now completely handled in utils.c.
* Updated NpdmSystemCallId_Count to reflect changes introduced in 12.0.0.
* Added NcaMainSignatureKeyGeneration enum.
* NCA main signature moduli are now retrieved from FS .rodata at runtime.
* Simplified lock management in usb.c by using a single global mutex with scoped locks instead of three different r/w locks.
* Updated FatFs to R0.14b.
* Enabled 64-bit LBA support in FatFs to potentially support custom eMMC replacements / resized USER partitions in the future.
* Updated LZ4 to v1.9.3.
* Fixed typos.
* USB gamecard dumper PoC now only dumps the Initial Data area.
* Updated to-do list.
* Refactored keydata handling.
* Sealed NCA KAEKs are now generated at startup, and NCA key area entries are now decrypted by keysDecryptNcaKeyAreaEntry(), reducing the number of calls to spl functions.
* The eTicket RSA device key is now retrieved and decrypted at startup. RSA-OAEP wrapped titlekeys are now decrypted by keysDecryptRsaOaepWrappedTitleKey().
* Renamed titlekek -> ticket common key throughout the codebase.
* Added NcaKeyAreaEncryptionKeyIndex_Count and NcaKeyGeneration_Max enum values to nca.h.
* Proper usage of strcasecmp() in some functions.
* Moved syscall hint checks from keys.c to mem.c.
* Define illegal FS characters as an array rather than a char pointer.
* Services are now initialized before the CFW type checks.
* Fixed pcv/clkrst service initialization.
* Implemented additional thread safety and logfile output to service functions.
* Slightly tweaked running service checks.
* Added proper Markdown documentation for the USB ABI.
