Hello Malinen,
Thank you for your reply.
the hostapd version I used is 0.6.9, and the version of openssl is 0.9.8i, and How can I confirm if the SHA256 is enable or not?
I will use the newer openssl  to try. 
But I'm confuzed that the freeradius 2.1.6 combined with the openssl 0.9.8i is ok for the eap-tls.
