NAME

       CURLOPT_KEYPASSWD - 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 need 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

       All TLS based protocols: HTTPS, FTPS, IMAPS, POP3S, SMTPS etc.

EXAMPLE

       CURL *curl = curl_easy_init();

         curl_easy_setopt(curl, CURLOPT_URL, "https://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);
       }
