# NAME

CURLOPT_PROXY_TLSAUTH_PASSWORD - password to use for proxy TLS authentication

# SYNOPSIS

~~~c
#include <curl/curl.h>

CURLcode curl_easy_setopt(CURL *handle, CURLOPT_PROXY_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_PROXY_TLSAUTH_TYPE(3) option. Requires that the
CURLOPT_PROXY_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.

# DEFAULT

NULL

# %PROTOCOLS%

# EXAMPLE

~~~c
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_PROXY, "https://proxy.example");
    curl_easy_setopt(curl, CURLOPT_PROXY_TLSAUTH_TYPE, "SRP");
    curl_easy_setopt(curl, CURLOPT_PROXY_TLSAUTH_USERNAME, "user");
    curl_easy_setopt(curl, CURLOPT_PROXY_TLSAUTH_PASSWORD, "secret");
    res = curl_easy_perform(curl);
    curl_easy_cleanup(curl);
  }
}
