Thanks for your information.
I read this website and that is just some concept introduce, not practice case, I want to practice deploy manual, such as HP OpenView.....Certificates of third-party applications
Just a tip from some experience related to Certs & vPro. You'll want to ensure the key length is set to a value supported by AMT. Currently, AMT cannot use a key length of 4096 bits, so your provisioning will fail if you've set up your CA with a key length of 4096 bits.
