CURLOPT_SSH_HOST_PUBLIC_KEY_MD5(3)                    curl_easy_setopt options

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 connection to the host unless
       the md5sums match.

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

DEFAULT
       NULL

PROTOCOLS
       SCP and SFTP

EXAMPLE
       CURL *curl = curl_easy_init();
       if(curl) {
         curl_easy_setopt(curl, CURLOPT_URL, "sftp://example.com/file");
         curl_easy_setopt(curl, CURLOPT_SSH_HOST_PUBLIC_KEY_MD5,
                          "afe17cd62a0f3b61f1ab9cb22ba269a7");
         ret = curl_easy_perform(curl);
         curl_easy_cleanup(curl);
       }

AVAILABILITY
