CURLOPT_PROXY_KEYPASSWD(3)

NAME
CURLOPT_PROXY_KEYPASSWD - passphrase for the proxy private key

SYNOPSIS
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_PROXY_KEYPASSWD, char *pwd);

DESCRIPTION
This option is for connecting to an HTTPS proxy, not an HTTPS server. Pass a pointer to a null-terminated string as parameter. It will be used as the password required to use the CURLOPT_PROXY_SSLKEY(3) private key. You never needed a pass phrase to load a certificate but you need one to load your private key. The application does not have to keep the string around after setting this option.

DEFAULT
NULL

PROTOCOLS
Used with HTTPS proxy

EXAMPLE
CURL *curl = curl_easy_init();
if(curl) {
  curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/foo.bin");
  curl_easy_setopt(curl, CURLOPT_PROXY, "https://proxy:443");
  curl_easy_setopt(curl, CURLOPT_PROXY_KEYPASSWD, "superman");
  ret = curl_easy_perform(curl);
  curl_easy_cleanup(curl);
}

AVAILABILITY
Added in 7.52.0

RETURN VALUE
Returns CURLE_OK if TLS enabled, CURLE_UNKNOWN_OPTION if not, or CURLE_OUT_OF_MEMORY if there was insufficient heap space.
