Technical Documentation

Engineering guides for RookVPN privacy tools — leak testing, curl diagnostics, encrypted file transfer, and VPN setup.

VPN Leak Testing Guide

Learn how to run a full VPN leak test covering IP, DNS, WebRTC, and IPv6 — and fix failures before you trust the tunnel.

Hiddify Setup Guide

Download Hiddify, import your RookVPN subscription, and connect on any platform.

Free VPN with No Logs

Get a free, zero-logs VPN profile in minutes and confirm your traffic and identity stay private.

Online curl Tool Guide

Run curl commands from your browser to check your public IP, inspect response headers, and test endpoints without installing curl locally.

Hiddify on Windows

Step-by-step Windows setup for RookVPN using the Hiddify desktop client.

Hiddify on iOS

Import your RookVPN subscription into Hiddify on iOS and connect securely.

DNS Leak Test & Fix

Stop DNS queries from bypassing your VPN tunnel and exposing browsing metadata to your ISP.

WebRTC Leak Test & Fix

Prevent browsers from exposing your real IP through WebRTC STUN requests while a VPN is active.

IPv6 Leak Test & Fix

When IPv6 is enabled locally but not tunneled, websites may see your real ISP IPv6 address even if IPv4 goes through the VPN.

Using the RookCheck Suite

RookCheck bundles browser-based tests to audit IP visibility, VPN leaks, and fingerprinting surface — free at rookvpn.com/check.

RookSecret One-Time Secrets

Share passwords, tokens, and recovery codes through links that expire after one view or a time limit you choose.

Client-Side Crypto Tools

Inspect JWTs, generate secure passwords, and compute checksums locally — nothing is uploaded to RookVPN.

Free vs Paid VPN Plans

Start with a free no-logs profile, verify with RookCheck, then upgrade when you need longer access or priority support.

Hash Generator Guide

Pick the hash that matches the job. Checksums and password hashes are not interchangeable.

Password Generator Guide

A strong password is one you can store and an attacker cannot guess. Clever substitutions are not a scheme.

JWT Decoder Guide

Decode shows you the JSON. Verify tells you whether the key you hold signed it. Your API still has to enforce the claims.

Subnet Calculator Guide

Identify one network, or split a parent block into several prefix lengths, without guessing the next boundary.
