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(3)   and
              CURLOPT_PROXY_TLSAUTH_PASSWORD(3) options.

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

DEFAULT

       blank

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.
