Key Types

Type AES Engine Keyslot Description
0 0x0D Used to decrypt the SSL client cert/private-key stored in ClCertA.
1 0x2D Used to generate the UDS local-WLAN CCMP key.
2 0x31 This is used by NS for the APT AES-CCM Wrap/Unwrap commands. These two NS commands are used by the Mii Maker application for the encrypted Mii data in the Mii QR codes.
3 0x38 BOSS
4 0x32 ?
5 0x39 This is used by the Download Play module.
6 0x2E ?
