We are trying to put some background noise to measure "Session Size" with the help of tool called " APPPerfect a load generating tool". For this we are taking help of the third party company.

But, when they are trying to generate/ record scripts using the "APPPERFECT" , they see some SSL certificate issue. Did you face the same problem?

they are asking the certificate in PKCS 12(.PFX) format, so they can import it into AppPerfect for load testing. But, when I try to look into it, .PFX format is disabled and don't know how to enable it?

Do you have any idea how to do that ?
