No, it does not. CRL verification is tls_openssl.c is reserved for
hostapd (i.e., EAP server). Verifying CRL in the supplicant side is
somewhat difficult since the network connection is not usually available
when the CRL would need to be fetched from somewhere. Do you have an
authentication server that is sending out the CRL somehow as part of the
TLS handshake or would the CRL be downloaded into the client manually?
