Is HMAC-SHA hash argorithm available on Fez Spider?


I write code to access REST API Web service with OAuth authentication.
I use Microsoft.SPOT.Cryptoki.Mechanism class to get hash argorithm mechanism by

var mech = new Mechanism(MechanismType.SHA_1_HMAC);

This code works on Emulator on Windows but causes Not Supported Exception on Fez Spider.
Is hash argorithm implementation a part of firmware?
If so, Fez Spider’s firmware doesn’t have OpenSV imelementation , dose it?

I use latest Gadgeteer SDK v4.2.
