NAME

       CURLOPT_SSH_PUBLIC_KEYFILE - 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 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.

DEFAULT

       NULL

PROTOCOLS

       SFTP and SCP

EXAMPLE

       int main(void)
       {
         CURL *curl = curl_easy_init();
         if(curl) {
           CURLcode res;
           curl_easy_setopt(curl, CURLOPT_URL, "sftp://example.com/file");
           curl_easy_setopt(curl, CURLOPT_SSH_PUBLIC_KEYFILE,
                            "/home/clarkkent/.ssh/id_rsa.pub");
           res = 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
