The lscfcaptcha Go module is a custom Cloudflare Turnstile processor. The Turnstile validation is still performed by Cloudflare. This executable will check if the response is successful and if so, notify the web server that the client successfully completed the Turnstile challenge.
Copy the binary from the latest release into your server root path:
mv _recaptcha /usr/local/lsws/lsrecaptcha/_recaptcha
chmod 555 /usr/local/lsws/lsrecaptcha/_recaptchaReplace the existing _recaptcha.shtml file in /usr/local/lsws/lsrecaptcha/ with the new one. Restart the server to take effect.
Once you have replaced the binary, modify OLS/LSWS configuration to use recaptcha, not hcaptcha.
Make sure that you configure the hostnames properly in Cloudflare's Dashboard, else requests would fail.
