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
