CURLOPT_TLSAUTH_USERNAME(3)

Library Functions Manual

CURLOPT_TLSAUTH_USERNAME(3)

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.
