== LoadAesKey ==
[2.0.0+] Now verifies that the engine used (0..3) is locked/owned by the current spl session, otherwise errors with 0xD21A. Previously engine was hardcoded to 0.
== GenerateAesKey ==
[2.0.0+] Previously it used engine 0 always. Now it tries to allocate an engine to be used, returns 0xD01A if they're all busy. After command is done, the engine is released.

Last SPL cmd used by [[SSL_services|SSL]]-sysmodule for TLS client-privk.
Last SPL cmd used by [[SSL_services|SSL]]-sysmodule for TLS client-privk.
== UninitializeSpl ==
== GenerateAesKeyOther ==
Returns a single u32 (always 3?) only once.
Scrambles with a different constant than non-"other" version.
[2.0.0+] Introduced same engine allocation code as for [[#GenerateAesKey]].
== DecryptAesCtr ==
[2.0.0+] Verifies the engine is locked by current session, same change as [[#LoadAesKey]].
== ComputeCmac ==
[2.0.0+] Verifies the engine is locked by current session, same change as [[#LoadAesKey]].
== SetKeyslotFromZ ==
[2.0.0+] Verifies the engine is locked by current session, same change as [[#LoadAesKey]].
== LockAesEngine ==
Returns the id of the engine that was locked, or 0xD01A if all engines are busy. You need to lock an engine before using AES functions.
== InitializeSpl ==
== UnlockAesEngine ==
Takes a single u32 (always 3?) only once.
Takes a single u32 and unlocks the engine with that id. It must be owned by current session otherwise 0xD21A will be returned.
