EAP-SIM simulation, Is there any oepnssl utilities that will calculate the MAC value for AT_MAC attribute in EAP-SIM

[Sanjay Kumar (sanjaku5)]

Hi All,
        I need a help to calculate the MAC value for  AT_MAC attribute in 
EAP-SIM.

Is there any openssl utilities (e.g. openssl dgst .....) or online tool
which will calculate the MAC value when we pass the required input e.g AT_RAND.


Thanks,
Sanjay
