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 null-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.

  curl_easy_setopt(curl, CURLOPT_SSLKEY, "key.pem");
  curl_easy_setopt(curl, CURLOPT_KEYPASSWD, "superman");
  ret = curl_easy_perform(curl);
  curl_easy_cleanup(curl);
}
