NAME

       CURLOPT_PROXY_SSLCERT - set SSL 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 a HTTPS proxy, not a HTTPS server.

       Pass  a  pointer  to  a zero 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_SSLCERTTYPE(3).

       With NSS or Secure Transport, this can also be the nickname of the certificate 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 nickname.

       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
