Algorithm Types
| Type | Description |
|---|---|
| 0 | CBC Encrypt |
| 1 | CBC Decrypt |
| 2 | CTR Encrypt |
| 3 | CTR Decrypt |
| 4 | CCM Encrypt |
| 5 | CCM Decrypt |
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 | This is used by the StreetPass CECD module to generate the CCMP key passed to nwm::CEC commands, when beginning StreetPass communications. |
| 7 | Invalid | |
| 8 | 0x36 | Support for this keytype was added with the NATIVE_FIRM updated with 2.2.0-X. When the running NATIVE_FIRM doesn't support this keytype, the result is the same as using keytype7. This is used by the friends module. |
| >=9 | Invalid, same as keytype7. |
Description
This is used to encrypt/decrypt data via the AES engine. AES-CCM is not supported by this command, PSPXI:EncryptSignDecryptVerifyAesCcm must be used for AES-CCM instead.
