CURLOPT_TLSAUTH_PASSWORD(3) Library Functions Manual CURLOPT_TLSAUTH_PASSWORD(3)

CURLOPT_TLSAUTH_PASSWORD - password to use for TLS authentication

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

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.

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

NULL

All TLS based protocols: HTTPS, FTPS, IMAPS, POP3S, SMTPS etc.

This option works only with the following TLS backends: GnuTLS and OpenSSL

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);
  }
}

Added in 7.21.4, with the OpenSSL and GnuTLS backends only

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