NAME

       CURLOPT_TLSAUTH_TYPE - TLS authentication methods

SYNOPSIS

       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_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. 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_TLSAUTH_USERNAME(3)    and
              CURLOPT_TLSAUTH_PASSWORD(3) options.

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

              TLS SRP does not work with TLS 1.3.

DEFAULT

       blank

PROTOCOLS

       All TLS-based protocols

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_TLSAUTH_TYPE, "SRP");
           curl_easy_setopt(curl, CURLOPT_TLSAUTH_USERNAME, "user");
           curl_easy_setopt(curl, CURLOPT_TLSAUTH_PASSWORD, "secret");
           res = curl_easy_perform(curl);
           curl_easy_cleanup(curl);
         }
       }

AVAILABILITY

       You  need  to  build libcurl with GnuTLS or OpenSSL with TLS-SRP support for this to work.
       Added in 7.21.4

RETURN VALUE

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