NAME

       CURLOPT_TLSAUTH_USERNAME - username to use for TLS authentication

SYNOPSIS

       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_TLSAUTH_USERNAME, char *user);

DESCRIPTION

       Pass  a  char  pointer as parameter, which should point to the null-terminated username to
       use for the TLS authentication method specified with the  CURLOPT_TLSAUTH_TYPE(3)  option.
       Requires that the CURLOPT_TLSAUTH_PASSWORD(3) option also be set.

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

       This feature relies on TLS SRP which does not work with TLS 1.3.

DEFAULT

       NULL

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 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

       Added in curl 7.21.4

RETURN VALUE

       Returns   CURLE_OK   if   the   option  is  supported,  CURLE_UNKNOWN_OPTION  if  not,  or
       CURLE_OUT_OF_MEMORY if there was insufficient heap space.
