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.

=== Hardware Types ===
+
Takes an input u32 '''ConfigItem''' and an input u64 '''ConfigValue'''.

   −
nx-abca2 hardware types are variations of the retail form factor.
+
== ImportLotusKey ==
 +

   −
=== Notes ===
+
Takes an input type-0x9 buffer '''DataIn''', an input 16-byte '''AccessKey''', an input 16-byte '''KeySource''' and an input u32 '''Version''' (0 for normal keys or 1 for extended keys).
   −

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

Kernel reads id12 when setting up memory-related code. If bit0 is set, it will memset various allocated memory-regions with 0x58, 0x59, 0x5A ('X', 'Y', 'Z') instead of zero. This allows Nintendo devs to find uninitialized memory bugs. If bit17-16 is 0b01, the kernel assumes 6GB of DRAM instead of 4GB.

This is "nn::spl::detail::ISslInterface".
   −
== UnlockAesEngine ==
+
{| class="wikitable" border="1"
Takes a single u32 and unlocks the engine with that id. It must be owned by current session otherwise 0xD21A will be returned.
