NAME
CURLOPT_PROXY_SSLCERT - HTTPS proxy client certificate
SYNOPSIS
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_PROXY_SSLCERT, char *cert);
DESCRIPTION
This option is for connecting to an HTTPS proxy, not an HTTPS server.
Pass a pointer to a null-terminated string as parameter. The string
should be the file name of your client certificate used to connect to
the HTTPS proxy. The default format is "P12" on Secure Transport and
"PEM" on other engines, and can be changed with CURLOPT_PROXY_SSLCERT-
TYPE(3).
With NSS or Secure Transport, this can also be the nickname of the cer-
tificate you wish to authenticate with as it is named in the security
database. If you want to use a file from the current directory, please
precede it with "./" prefix, in order to avoid confusion with a nick-
name.
When using a client certificate, you most likely also need to provide a
private key with CURLOPT_PROXY_SSLKEY(3).
The application does not have to keep the string around after setting
this option.
DEFAULT
NULL
PROTOCOLS
Used with HTTPS proxy
