Programs in NXTools currently recognise the following keys (## represents a hexadecimal number between 00 and 1F):
|
|
|
|
```
|
|
; Key Sources
|
|
master_key_## : Master key, used to derive other keys. (0x10 bytes)
|
|
aes_kek_generation_source : Used to derive other aes-keks. (0x10 bytes)
|
|
aes_key_generation_source : Used to derive other aes-keys. (0x10 bytes)
|
|
package2_key_source : Used with master_key_## to derive package2_key_##. (0x10 bytes)
|
|
ticket_commonkey_source : Used with master_key_## to derive ticket_commonkey_##. (0x10 bytes)
|

# Compatibility with hactool keyset files
|
|
NXTools keyset files share the same keyset file format as [hactool](https://github.com/SciresM/hactool/blob/master/KEYS.md), but names of keys may differ. For compatibility, hactool names for equivalent keys are accepted.
|
|
```
|
|
titlekek_source : hactool alias for ticket_commonkey_source
|
|
header_key_source : hactool alias for nca_header_key_source
|
|
header_kek_source : hactool alias for nca_header_kek_source
|
|
key_area_key_application_source : hactool alias for nca_body_keak_application_source
|
|
key_area_key_ocean_source : hactool alias for nca_body_keak_ocean_source
|
|
key_area_key_system_source : hactool alias for nca_body_keak_system_source
|
|
titlekek_## : hactool alias for ticket_commonkey_##
|
|
header_key : hactool alias for nca_header_key
|
|
key_area_key_application_## : hactool alias for nca_body_keak_application_##
|
|
key_area_key_ocean_## : hactool alias for nca_body_keak_ocean_##
|
|
key_area_key_system_## : hactool alias for nca_body_keak_system_##
