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 is used as the password required to use the CURLOPT_PROXY_SSLKEY(3) private key. You never need a passphrase 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.

Using this option multiple times makes the last set string override the previous ones. Set it to NULL to disable its use again.

DEFAULT

NULL

EXAMPLE

int main(void)
{
  CURL *curl = curl_easy_init();
  if(curl) {
    CURLcode res;
    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");
    res = curl_easy_perform(curl);
    curl_easy_cleanup(curl);
  }
}
