.TH CURLOPT_SSH_PUBLIC_KEYFILE 3 "19 Jun 2014" libcurl libcurl
|
||
|
|
.SH NAME
|
||
|
|
CURLOPT_SSH_PUBLIC_KEYFILE \- public key file for SSH auth
|
||
|
|
.SH SYNOPSIS
|
||
|
|
.nf
|
||
|
|
#include <curl/curl.h>
|
||
|
|
|
||
|
|
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_SSH_PUBLIC_KEYFILE,
|
||
|
|
char *filename);
|
||
|
|
.SH DESCRIPTION
|
||
|
|
Pass a char * pointing to a \fIfilename\fP for your public key. If not used,
|
||
|
|
libcurl defaults to \fB$HOME/.ssh/id_dsa.pub\fP if the HOME environment
|
||
|
|
variable is set, and just "id_dsa.pub" in the current directory if HOME is not
|
||
|
|
set.
|
||
|
|
|
||
|
|
If NULL (or an empty string) is passed, libcurl passes no public key to
|
||
|
|
libssh2, which then computes it from the private key. This is known to work
|
||
|
|
with libssh2 1.4.0+ linked against OpenSSL.
|
||
|
|
|
||
|
|
The application does not have to keep the string around after setting this
|
||
|
|
option.
|
||
|
|
.SH DEFAULT
|
||
|
|
NULL
|
||
|
