# NAME
|
||
|
|
|
||
|
|
CURLOPT_KEYPASSWD - passphrase to private key
|
||
|
|
|
||
|
|
# SYNOPSIS
|
||
|
|
|
||
|
|
~~~c
|
||
|
|
#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
