I have applied for a x.509 client certificate of Attestation Service for Intel® SGX last year. And now the certificate is expired. Does anyone know how I can renew the certificate? I emailed firstname.lastname@example.org and haven't got a reply yet. Thanks for the possible help.
Unless you have signed a commercial license with Intel, we no longer support x.509 certs for SGX remote attestation. You will need to convert to using our new SPID/key based APIs.
