CURLOPT_SSH_HOST_PUBLIC_KEY_MD5(3) | Library Functions Manual | CURLOPT_SSH_HOST_PUBLIC_KEY_MD5(3) |
NAME¶
CURLOPT_SSH_HOST_PUBLIC_KEY_MD5 - 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 pointer 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 aborts the connection to the host unless the MD5 checksum match.
MD5 is a weak algorithm. We strongly recommend using CURLOPT_SSH_HOST_PUBLIC_KEY_SHA256(3) instead.
The application does not have to keep the string around after setting this option.
DEFAULT¶
NULL
PROTOCOLS¶
SCP and SFTP
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_HOST_PUBLIC_KEY_MD5,
"afe17cd62a0f3b61f1ab9cb22ba269a7");
res = curl_easy_perform(curl);
curl_easy_cleanup(curl);
} }
AVAILABILITY¶
Added in 7.17.1
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.
