Prod Keys are not a single key but a collection. The v2101 set includes:
| Key Name | Purpose | Exclusive Trait |
|----------|---------|------------------|
| master_key_0A | Title decryption for HOS 12.x–13.x | Derived from a unique device root key |
| key_area_key (application, ocean, system) | NCA header decryption | Varies by fuses burned |
| package2_key | Kernel & package2 verification | Tied to bootloader phase |
| tsc_key | TSEC firmware authentication | Specific to Mariko or Erista v2 |
| bis_key (crypt, tweak) | Partition encryption (PRODINFO, SAFE) | Exclusive to eMMC hardware hash |
