+.TH CURLOPT_CRLFILE 3 "19 Jun 2014" "libcurl 7.37.0" "curl_easy_setopt options"
+.SH NAME
+CURLOPT_CRLFILE \- specify a Certificate Revocation List file
+.SH SYNOPSIS
+#include <curl/curl.h>
+
+CURLcode curl_easy_setopt(CURL *handle, CURLOPT_CRLFILE, char *file);
+.SH DESCRIPTION
+Pass a char * to a zero terminated string naming a \fIfile\fP with the
+concatenation of CRL (in PEM format) to use in the certificate validation that
+occurs during the SSL exchange.
+
+When curl is built to use NSS or GnuTLS, there is no way to influence the use
+of CRL passed to help in the verification process. 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.
+.SH DEFAULT
+NULL
+.SH PROTOCOLS
+All TLS-based protocols
+.SH EXAMPLE
+TODO
+.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.
