NAME

CURLOPT_PROXY_KEYPASSWD - set passphrase to proxy private key

SYNOPSIS

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

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