NAME
CURLOPT_PROXY_TLSAUTH_TYPE - HTTPS proxy TLS authentication methods

SYNOPSIS
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_PROXY_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 used for the HTTPS connection. 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_PROXY_TLSAUTH_USERNAME(3) and CURLOPT_PROXY_TLSAUTH_PASSWORD(3) options. The application does not have to keep the string around after setting this option.
