NAME

6       CURLOPT_PROXY_SSLCERT - HTTPS proxy client certificate
7

SYNOPSIS

9       #include <curl/curl.h>
10
11       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_PROXY_SSLCERT, char *cert);
12

DESCRIPTION

14       This option is for connecting to an HTTPS proxy, not an HTTPS server.
15
16       Pass  a  pointer  to  a null-terminated string as parameter. The string
17       should be the file name of your client certificate used to  connect  to
18       the  HTTPS  proxy.  The default format is "P12" on Secure Transport and
19       "PEM" on other engines, and can be changed with  CURLOPT_PROXY_SSLCERT‐
20       TYPE(3).
21
22       With NSS or Secure Transport, this can also be the nickname of the cer‐
23       tificate you wish to authenticate with as it is named in  the  security
24       database.  If you want to use a file from the current directory, please
25       precede it with "./" prefix, in order to avoid confusion with  a  nick‐
26       name.
27
28       When using a client certificate, you most likely also need to provide a
29       private key with CURLOPT_PROXY_SSLKEY(3).
30
31       The application does not have to keep the string around  after  setting
32       this option.
