CURLOPT_KEYPASSWD(3)

NAME
CURLOPT_KEYPASSWD - set passphrase to private key

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

DESCRIPTION
Pass a pointer to a zero terminated string as parameter. It will be used as the password required to use the CURLOPT_SSLKEY(3) or CURLOPT_SSH_PRIVATE_KEYFILE(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
All TLS based protocols: HTTPS, FTPS, IMAPS, POP3S, SMTPS etc.

EXAMPLE
CURL *curl = curl_easy_init();
if(curl) {
  curl_easy_setopt(curl, CURLOPT_URL, "http://example.com/foo.bin");
  curl_easy_setopt(curl, CURLOPT_SSLCERT, "client.pem");
  curl_easy_setopt(curl, CURLOPT_SSLKEY, "key.pem");
  curl_easy_setopt(curl, CURLOPT_KEYPASSWD, "superman");
  ret = curl_easy_perform(curl);
  curl_easy_cleanup(curl);
}
