GenerateInquiryCode

This cmd takes no input, and produces 0x20 bytes of raw output containing snprintf("%02d%08llu", 10, [inquiry_rnd]) on <= 3.0.0. This changed on 3.0.1 to produce "11(...)" instead of "10(...)".

The random number generation relies on TinyMT.

CheckMasterKey

This cmd takes the 0x20 bytes produced by GenerateInquiryCode, and an 0x20 byte X descriptor containing snprintf("%08llu", master_key), and returns a bool 00 if the master key is not valid, and 01 if it is.

Master Keys are validated as follows on <= 3.0.0: first, svcSleepThread(1000000000LL) is called to introduce a delay to prevent brute force attacks. Then, strlen(master_key) is called -- if this is not 8, 0 is returned. Next, the inquiry code is regenerated and snprintf("%02d%08llu", 10, generated_inquiry_rnd) is compared to the inquiry data passed in as an argument. If this doesn't match, 0 is returned. Then, hmac-sha256(snprintf("%02d%08llu", 10, generated_inquiry_rnd)) is called using hardcoded keydata, and the master key argument is compared to snprintf("%08llu", (hmac_result & 0xFFFFFFFFFFFF) % 100000000). If this matches, 1 is returned, otherwise 0 is returned.

On 3.0.1 this was changed to use different hardcoded keydata, and to pass 11 as the snprintf argument instead of 10.
