CURLOPT_PROXY_SSLKEY(3)    curl_easy_setopt options    CURLOPT_PROXY_SSLKEY(3)

NAME
       CURLOPT_PROXY_SSLKEY  -  specify  private keyfile for TLS and SSL proxy
       client cert

SYNOPSIS
       #include <curl/curl.h>

       CURLcode  curl_easy_setopt(CURL  *handle,  CURLOPT_PROXY_SSLKEY,   char
       *keyfile);

DESCRIPTION
       Pass  a  pointer  to  a zero terminated string as parameter. The string
       should be the file name of your private key used for connecting to  the
       HTTPS  proxy.  The default format is "PEM" and can be changed with CUR-
       LOPT_PROXY_SSLKEYTYPE(3).

       (iOS and Mac OS X only) This  option  is  ignored  if  curl  was  built
       against  Secure  Transport. Secure Transport expects the private key to
       be already present in the keychain or PKCS#12 file containing the  cer-
       tificate.

       The  application  does not have to keep the string around after setting
       this option.

DEFAULT
       NULL

PROTOCOLS
