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 is used as the password required to use the CURLOPT_SSLKEY(3) or CURLOPT_SSH_PRIVATE_KEYFILE(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
