NAME

CURLOPT_TLSAUTH_USERNAME - user name to use for TLS authentication

SYNOPSIS

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

DESCRIPTION

Pass a char * 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 in TLS SRP which doesn't work with TLS 1.3.

DEFAULT

NULL

PROTOCOLS

All TLS-based protocols

EXAMPLE

CURL *curl = curl_easy_init();
if(curl) {
  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");
  ret = curl_easy_perform(curl);
  curl_easy_cleanup(curl);
}

AVAILABILITY

Added in 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.
