I find myself going in circles trying to pull OIDs from a certificate's
"X509v3 Extended Key Usage" (as `openssl x509 -in foo.pem -text` shows)
When I read in the cert:
cert, err := x509.ParseCertificate(block.Bytes)
the ExtKeyUsage, UnknownExtKeyUsage, nor PolicyIdentifiers contain the list
of extensions that I know are in the PEM certificate file.
Does anyone have a pointer on how to do this? or is it even available?
