       gnutls_x509_crq_set_key_purpose_oid - API function
       #include <gnutls/x509.h>
       int gnutls_x509_crq_set_key_purpose_oid(gnutls_x509_crq_t crq,
       const void * oid, unsigned int critical);
       gnutls_x509_crq_t crq
                   a certificate of type gnutls_x509_crq_t
       const void * oid
                   a pointer to a null-terminated string that holds the

       unsigned int critical
                   Whether this extension will be critical or not
       This function will set the key purpose OIDs of the Certificate.
       These are stored in the Extended Key Usage extension (2.5.29.37)

       Subsequent calls to this function will append OIDs to the OID
