CURLOPT_TLSAUTH_PASSWORD(3)

NAME
CURLOPT_TLSAUTH_PASSWORD - password to use for TLS authentication

SYNOPSIS
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_TLSAUTH_PASSWORD, char *pwd);

DESCRIPTION
Pass a char pointer as parameter, which should point to the null-terminated password to use for the TLS authentication method specified with the CURLOPT_TLSAUTH_TYPE(3) option. Requires that the CURLOPT_TLSAUTH_USERNAME(3) option also be set. The application does not have to keep the string around after setting this option. Using this option multiple times makes the last set string override the previous ones. Set it to NULL to disable its use again. 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.
