SPL ("Secure Platform services") is responsible for handling all cryptographic operations within the system and relaying them to the [[SMC|Secure Monitor]] when necessary.
  
 
During [1.0.0-3.0.2], the only existing services were "csrng" and "spl:". However, in [4.0.0+] the "spl:" service was refactored and split into new services with different permission levels. Each service exposes the IPC command list differently in order to prevent cryptographic operations to take place in the wrong context.

In [2.0.0+] where previously only one AES keyslot was used, there is now support for 4 of them and when the session closes, all allocated AES keyslots are automatically freed.

 +
Takes 3 input type-0x9 buffers '''DataIn''', '''ModIn''' and '''LabelHashIn'''.
 +
 
 +

nx-abcb (Copper) is the SDEV unit. Among other differences, this has extra hardware to support HDMI output.
 
 
 
nx-abca2 (Icosa) hardware types are variations of the retail form factor.
 
 
 
=== SecurityEngineIrqNumber ===
 
SPL uses this for setting up the security engine IRQ.
 
 
 
=== Version ===
 
The current [[Package2#Versions|Package1 Maxver Constant]] - 1.
 
 
 
=== HardwareType ===
 
[1.0.0+] This item is obtained by checking bits 8 and 2 from [[Fuse_registers#FUSE_RESERVED_ODM4|FUSE_RESERVED_ODM4]]. It can be 0 (Icosa), 1 (Copper) or 3 (Invalid).
 
 
 
[4.0.0+] This item is obtained by checking bits 8, 2 and 16-19 from [[Fuse_registers#FUSE_RESERVED_ODM4|FUSE_RESERVED_ODM4]]. It can be 0 (Icosa), 1 (Copper), 3 (Mariko) or 4 (Invalid).
 
 
 
A value of 2 (Hoag?) is always mapped to 4 (Invalid).
 
 
 
=== IsRetail ===
 
This item is obtained by checking bits 9 and 0-1 from [[Fuse_registers#FUSE_RESERVED_ODM4|FUSE_RESERVED_ODM4]]. It can be 0 (Debug), 1 (Retail) or 2 (Invalid).
 
 
 
=== IsRecoveryBoot ===
 
Used to determine if the system is booting from SafeMode firmware.
 
 
 
=== DeviceId ===
 
[[NIM_services|NIM]] checks if this item matches the [[Settings_services|set:cal]] DeviceId with byte7 cleared. If they don't match, a panic is thrown.
 
 
 
=== BootReason ===
 
Used to determine how the system booted.
 
 
 
=== MemoryArrange ===
 
[[Process Manager services|PM]] uses this item for selecting the appropriate size for each [[SVC#LimitableResource|LimitableResource_Memory]].
 
 
 
=== IsDebugMode ===
 
Kernel uses this to determine behavior of svcBreak positive arguments. It will break instead of just force-exiting the process which is what happens on retail.
 
 
 
[2.0.0+] This is also used with certain debug [[SVC|SVCs]].
 
 
 
[3.0.0+] [[Loader services|RO]] checks this and if set then skipping NRR rsa signatures is allowed.

SPL ("Secure Platform services") is responsible for handling all cryptographic operations within the system and relaying them to the Secure Monitor when necessary.

During [1.0.0-3.0.2], the only existing services were "csrng" and "spl:". However, in [4.0.0+] the "spl:" service was refactored and split into new services with different permission levels. Each service exposes the IPC command list differently in order to prevent cryptographic operations to take place in the wrong context.

In [2.0.0+] where previously only one AES keyslot was used, there is now support for 4 of them and when the session closes, all allocated AES keyslots are automatically freed.

csrng

This is "nn::spl::detail::IRandomInterface".

Cmd Name
0 #GenerateRandomBytes

GenerateRandomBytes

Takes an output type-0xA buffer and fills it with random data from GenerateRandomBytes SMC. Same command for "spl:" and "csrng" services, except for buffer-type.

LoadAesKey

Wrapper for LoadAesKey SMC.

Takes an input u32 Keyslot , an input 16-byte AccessKey and an input 16-byte KeySource.
