Does the result after encrypt different?
Why need 2 crypto?

I suppose you mean components/wpa_supplicant/src/crypto?
This is part of the source code of wpa_supplicant library, used inside the wifi stack. It is indeed possible to re-write parts of this library to make use of HW crypto APIs, this is currently in our backlog.
