As said in this URL, use curl to pass some values to Intel. However, how can I get the values such as Ocp-Apim-Subscription-Key, encrypted_ppid, cpusvn, pcesvn, pceid.

Is there any script available?

Thanks!

Hi,

I am able to get all the pre-requisites needed for PCK Certificate downloading. I got Ocp-Apim-Subscription-Key, encrypted_ppid, cpusvn, pcesvn, pceid. However when I run curl command for retrieval I always get 404 Resource not found. Do you have any idea how to resolve it ??

{ "statusCode": 404, "message": "Resource not found" }

Thanks,

I just write a guide to get those values:

  1. encrypted_ppid
  2. cpusvn
  3. pcesvn
  4. pceid

 

You can read the guide in here:

The PPID, CPUSVN, PCESVN, PCEID can be retrieved by downloading and running Intel's PCK ID Retrieval Tool on an SGX-capable machine.

The subscription key is obtained by registering for it with Intel.

The API for retrieving the PCK cert will give an invalid key error if you leave the {brackets} around the subscription key. However, you should leave brackets around the PPID, CPUSVN, PCESVN, PCEID.

The SDK and PSW are not necessary for retrieving these values.
