The active bootloader's version (offset 0x2330 in the BCT) acts as an index to control which keyblob should be installed into the system.
The active bootloader's version (offset 0x2330 in the BCT) acts as an index (<code>version-1</code>) to control which keyblob should be installed into the system.
[[NS_Services|NS]] uses this during system updates to install the keyblob into the [[BCT#customer_data|customer data]] section in BCTs (offset 0x450).

Encrypted partitions use AES-XTS using the same non-standard tweak (tweak[0] = sectorIdx[MSB] .. tweak[15] = sectorIdx[LSB], if using 32bit sectorIdx that means tweak[0]..tweak[11] are 0, with tweak[12]..tweak[15] containing big-endian sectorIdx) as other Nintendo AES-XTS code, initial_sector = 0, and sector size 0x4000. All encrypted partitions use console unique keydata.
