+     If such a certificate is found during a verify operation it is 
+     rejected by default: this behaviour can be overridden by either
+     handling the new error X509_V_ERR_UNHANDLED_CRITICAL_EXTENSION or
+     by setting the verify flag X509_V_FLAG_IGNORE_CRITICAL. A new function
+     X509_supported_extension() has also been added which returns 1 if a
+     particular extension is supported.
