NAME

     CURLOPT_SSH_PUBLIC_KEYFILE - set public  key  file  for  SSH
     auth

SYNOPSIS

     #include <curl/curl.h>

     CURLcode curl_easy_setopt(CURL *handle, CURLOPT_SSH_PUBLIC_KEYFILE,
                               char *filename);

DESCRIPTION

     Pass a char * pointing to a filename for your public key. If
     not  used,  libcurl defaults to $HOME/.ssh/id_dsa.pub 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 will pass no
     public  key  to libssh2, which then tries to compute 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.

DEFAULT

     NULL

PROTOCOLS

     SFTP and SCP

EXAMPLE

     CURL *curl = curl_easy_init();
     if(curl) {
       curl_easy_setopt(curl, CURLOPT_URL, "sftp://example.com/file");
       curl_easy_setopt(curl, CURLOPT_SSH_PUBLIC_KEYFILE,
                        "/home/clarkkent/.ssh/id_rsa.pub");
       ret = curl_easy_perform(curl);
       curl_easy_cleanup(curl);
     }

AVAILABILITY

     The "" trick was added in 7.26.0

RETURN VALUE

     Returns   CURLE_OK   if    the    option    is    supported,
     CURLE_UNKNOWN_OPTION if not, or CURLE_OUT_OF_MEMORY if there
     was insufficient heap space.
