This should be done using special certificates known as Certificate Authorities (CA). The curve objects are useful as values for the argument accepted by Context.set_tmp_ecdh() to specify which elliptical curve should be used for ECDHE key exchange. Sometimes we only need a lightweight tool and don't want to configure openssl.cnf. The extension may be created from der data or from an extension oid and value.
