- make DEFAULT sections less repetitive - make historic mentions use HISTORY - generate the protocols section on `# %PROTOCOLS%` instead of guessing where to put it - generate the availability section on `# %AVAILABILITY%` instead of guessing where to put it - make the protocols section more verbose Closes #14227

# NAME
|
|
|
|
CURLOPT_PROXY_SSLCERT - HTTPS proxy client certificate
|
|
|
|
# SYNOPSIS
|
|
|
|
~~~c
|
|
#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 filename 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 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%
