CURLOPT_PROXY_TLSAUTH_USERNAME explained

Name

CURLOPT_PROXY_TLSAUTH_USERNAME - username to use for proxy TLS authentication

Synopsis

#include <curl/curl.h>
 
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_PROXY_TLSAUTH_USERNAME,
                          char *user);

Description

Pass a char pointer as parameter, which should point to the null-terminated username to use for the HTTPS proxy TLS authentication method specified with the CURLOPT_PROXY_TLSAUTH_TYPE option. Requires that the CURLOPT_PROXY_TLSAUTH_PASSWORD option also be set.

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

Using this option multiple times makes the last set string override the previous ones. Set it to NULL to disable its use again.

Default

NULL

Protocols

This functionality affects all TLS based protocols: HTTPS, FTPS, IMAPS, POP3S, SMTPS etc.

This option works only with the following TLS backends: GnuTLS and OpenSSL

Example

int main(void)
{
  CURL *curl = curl_easy_init();
  if(curl) {
    CURLcode res;
    curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/");
    curl_easy_setopt(curl, CURLOPT_PROXY, "https://proxy");
    curl_easy_setopt(curl, CURLOPT_PROXY_TLSAUTH_TYPE, "SRP");
    curl_easy_setopt(curl, CURLOPT_PROXY_TLSAUTH_USERNAME, "user");
    curl_easy_setopt(curl, CURLOPT_PROXY_TLSAUTH_PASSWORD, "secret");
    res = curl_easy_perform(curl);
    curl_easy_cleanup(curl);
  }
}
