NAME

6       CURLOPT_SSH_PUBLIC_KEYFILE - set public key file for SSH auth
7

SYNOPSIS

9       #include <curl/curl.h>
10
11       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_SSH_PUBLIC_KEYFILE,
12                                 char *filename);
13

DESCRIPTION

15       Pass  a char * pointing to a filename for your public key. If not used,
16       libcurl defaults to $HOME/.ssh/id_dsa.pub if the HOME environment vari‐
17       able  is set, and just "id_dsa.pub" in the current directory if HOME is
18       not set.
19
20       If NULL (or an empty string) is passed, libcurl will pass no public key
21       to  libssh2, which then tries to compute it from the private key.  This
22       is known to work with libssh2 1.4.0+ linked against OpenSSL.
23
24       The application does not have to keep the string around  after  setting
25       this option.
