Ernie provides raw storage in its EEPROM, named NVS (Non-Volatile Storage). The OS partitions some of this storage for encrypted data. The keys to encrypt/decrypt this data is from slots 0x502-0x504. They are derived by second_loader by encrypting using AES-256-CBC a seed with keyslot 0x216, which is console unique. Consoles with minimum firmware < 0.996 use a set of static keys found in second_loader. Minimum firmware comes from IdStorage SMI leaf.
