CURLOPT_TLSAUTH_TYPE(3)    Library Functions Manual    CURLOPT_TLSAUTH_TYPE(3)

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: 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_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.
