.SH NAME
|
|
CURLOPT_PROXY_CRLFILE \- HTTPS proxy Certificate Revocation List file
|
|
.SH SYNOPSIS
|
|
.nf
|
|
#include <curl/curl.h>
|
|
|
|
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_PROXY_CRLFILE, char *file);
|
|
.fi
|
|
.SH DESCRIPTION
|
|
This option is for connecting to an HTTPS proxy, not an HTTPS server.
|
|
|
|
Pass a char pointer to a null\-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 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_PROXY_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: HTTPS, FTPS, IMAPS, POP3S, SMTPS etc.
|
|
|
|
This option works only with the following TLS backends:
|
|
GnuTLS, OpenSSL and mbedTLS
|
|
.SH EXAMPLE
|
|
.nf
|
|
int main(void)
|
|
{
|
|
CURL *curl = curl_easy_init();
|
|
if(curl) {
|
|
CURLcode res;
|
|
curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/");
|
|
curl_easy_setopt(curl, CURLOPT_PROXY, "https://localhost:80");
|
|
curl_easy_setopt(curl, CURLOPT_PROXY_CRLFILE, "/etc/certs/crl.pem");
|
|
res = curl_easy_perform(curl);
|
|
curl_easy_cleanup(curl);
|
|
}
|
|
}
