CURLOPT_TLSAUTH_TYPE(3)

NAME
CURLOPT_TLSAUTH_TYPE - TLS authentication methods

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

DESCRIPTION
Pass a pointer to a null-terminated string as parameter. The string should be the method of the TLS authentication. Supported method is "SRP".

SRP TLS-SRP authentication. Secure Remote Password authentication for TLS is defined in RFC 5054 and provides mutual authentication if both sides have a shared secret. To use TLS-SRP, you must also set the CURLOPT_TLSAUTH_USERNAME(3) and CURLOPT_TLSAUTH_PASSWORD(3) options. The application does not have to keep the string around after setting this option. TLS SRP does not work with TLS 1.3.

DEFAULT
blank

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
You need to build libcurl with GnuTLS or OpenSSL with TLS-SRP support for this to work. Added in 7.21.4

RETURN VALUE
Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.
