When libcurl is built with +OpenSSL support, X509_V_FLAG_CRL_CHECK and X509_V_FLAG_CRL_CHECK_ALL are both +set, requiring CRL check against all the elements of the certificate chain if +a CRL file is passed. + +This option makes sense only when used in combination with the +\fICURLOPT_SSL_VERIFYPEER(3)\fP option. + +A specific error code (\fICURLE_SSL_CRL_BADFILE\fP) is defined with the +option. It is returned when the SSL exchange fails because the CRL file cannot +be loaded. A failure in certificate verification due to a revocation +information found in the CRL does not trigger this specific error. + +The application does not have to keep the string around after setting this +option. +.SH DEFAULT +NULL +.SH PROTOCOLS +All TLS-based protocols +.SH EXAMPLE +.nf +CURL *curl = curl_easy_init(); +if(curl) { + curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/"); + curl_easy_setopt(curl, CURLOPT_CRLFILE, "/etc/certs/crl.pem"); + ret = curl_easy_perform(curl); + curl_easy_cleanup(curl); +} +.fi +.SH AVAILABILITY +Added in 7.19.0 +.SH RETURN VALUE +Returns CURLE_OK if the option is supported, CURLE_UNKNOWN_OPTION if not, or +CURLE_OUT_OF_MEMORY if there was insufficient heap space. +.SH "SEE ALSO" +.BR CURLOPT_SSL_VERIFYPEER "(3), " CURLOPT_SSL_VERIFYHOST "(3), " +.BR CURLOPT_PROXY_CRLFILE "(3), " |
