0x36
|
This is used by the friends module.
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.

|
0x39
|
This is used by the NFC module.
Support for this keytype was added with the NATIVE_FIRM updated with 9.3.0-X. When the running NATIVE_FIRM doesn't support this keytype, the result is the same as using keytype7. Before selecting this keyslot, Process9 writes a keyY from the Process9 .(ro)data section(keydata is different for retail/dev units) to this keyslot. Once finished with crypto, Process9 restores the original keyY to this keyslot.

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.
