NAME

     CURLOPT_SSH_HOST_PUBLIC_KEY_MD5 -  checksum  of  SSH  server
     public key

SYNOPSIS

     #include <curl/curl.h>

     CURLcode curl_easy_setopt(CURL *handle, CURLOPT_SSH_HOST_PUBLIC_KEY_MD5,
                               char *md5);

DESCRIPTION

     Pass a char * pointing to a string containing 32 hexadecimal
     digits. The string should be the 128 bit MD5 checksum of the
     remote host's public key, and libcurl will reject  the  con-
     nection to the host unless the md5sums match.

     The application does not have  to  keep  the  string  around
     after setting this option.

DEFAULT

     NULL

PROTOCOLS

EXAMPLE

                        "afe17cd62a0f3b61f1ab9cb22ba269a7");
       ret = curl_easy_perform(curl);
       curl_easy_cleanup(curl);
     }
