AES function does not implement base functions . As a result , only x86 platform can support AES functions now .
That's different with other functions

I think we should implement base functions

Correct, it would be nice but note it's a very difficult task to write equal-time base functions in C.

Is there any method to make sure "equal-time" ? I am preparing AES job , I must setup some local test firstly

Hi, @haoyu01. you still working on this ? We are trying to add aes implemention using AES instruction set directly.

@IamFive , I haven't start AES job .
And I think that's good news for me .

@haoyu01 I am working on this for Huawei, but they did not accept this solution (using AES instruction like vextq_u8 directly). SO, i give up this task too.
