NAME

CURLOPT_PROXY_TLSAUTH_TYPE - HTTPS proxy TLS authentication methods  

SYNOPSIS

#include <curl/curl.h>

CURLcode curl_easy_setopt(CURL *handle, CURLOPT_PROXY_TLSAUTH_TYPE,
                          char *type);

 

DESCRIPTION

Pass a pointer to a null-terminated string as parameter. The string should be the method of the TLS authentication used for the HTTPS connection. Supported method is "SRP".

Using this option multiple times makes the last set string override the previous ones. Set it to NULL to restore to internal default.

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

SRP

TLS-SRP authentication. Secure Remote Password authentication for TLS is defined in RFC 5054 and provides mutual authentication if both sides have a shared secret. To use TLS-SRP, you must also set the CURLOPT_PROXY_TLSAUTH_USERNAME(3) and CURLOPT_PROXY_TLSAUTH_PASSWORD(3) options.

 

DEFAULT

blank  

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 result;
    curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/");
    curl_easy_setopt(curl, CURLOPT_PROXY, "https://proxy.example");
    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");
    result = curl_easy_perform(curl);
    curl_easy_cleanup(curl);
  }
}
