23 .TH CURLOPT_PROXY_SSLCERT 3 "16 Nov 2016" "libcurl 7.52.0" "curl_easy_setopt options"
24 .SH NAME
25 CURLOPT_PROXY_SSLCERT \- set SSL proxy client certificate
26 .SH SYNOPSIS
27 #include <curl/curl.h>
28
29 CURLcode curl_easy_setopt(CURL *handle, CURLOPT_PROXY_SSLCERT, char *cert);
30 .SH DESCRIPTION
31 This option is for connecting to an HTTPS proxy, not an HTTPS server.
32
33 Pass a pointer to a zero terminated string as parameter. The string should be
34 the file name of your client certificate used to connect to the HTTPS proxy.
35 The default format is "P12" on Secure Transport and "PEM" on other engines,
36 and can be changed with \fICURLOPT_PROXY_SSLCERTTYPE(3)\fP.
37
38 With NSS or Secure Transport, this can also be the nickname of the certificate
39 you wish to authenticate with as it is named in the security database. If you
40 want to use a file from the current directory, please precede it with "./"
41 prefix, in order to avoid confusion with a nickname.
42
43 When using a client certificate, you most likely also need to provide a
44 private key with \fICURLOPT_PROXY_SSLKEY(3)\fP.
45
46 The application does not have to keep the string around after setting this
47 option.
