CURLOPT_PROXY_TLSAUTH_TYPE explained

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".

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 and CURLOPT_PROXY_TLSAUTH_PASSWORD options.

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

Default

blank

Protocols

All

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);
  }
}

Availability

Added in 7.52.0

You need to build libcurl with GnuTLS or OpenSSL with TLS-SRP support for this to work.

Return value

Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.
