Learn how to run a full VPN leak test covering IP, DNS, WebRTC, and IPv6 — and fix failures before you trust the tunnel.
Engineering guides for RookVPN privacy tools — leak testing, curl diagnostics, encrypted file transfer, and VPN setup.
Learn how to run a full VPN leak test covering IP, DNS, WebRTC, and IPv6 — and fix failures before you trust the tunnel.
Verify what IP address the internet sees using curl and compare with in-browser tools.
Architecture overview of ephemeral file sharing sessions with optional E2EE on rookvpn.com/file.
Download Hiddify, import your RookVPN subscription, and connect on any platform.
Get a free, zero-logs VPN profile in minutes and confirm your traffic and identity stay private.
Run curl commands from your browser to check your public IP, inspect response headers, and test endpoints without installing curl locally.
Step-by-step Windows setup for RookVPN using the Hiddify desktop client.
Connect RookVPN on Android phones and tablets using Hiddify.
Import your RookVPN subscription into Hiddify on iOS and connect securely.
Understand RookVPN subscription URLs and how clients fetch server profiles over HTTPS.
Stop DNS queries from bypassing your VPN tunnel and exposing browsing metadata to your ISP.
Prevent browsers from exposing your real IP through WebRTC STUN requests while a VPN is active.
When IPv6 is enabled locally but not tunneled, websites may see your real ISP IPv6 address even if IPv4 goes through the VPN.
RookCheck bundles browser-based tests to audit IP visibility, VPN leaks, and fingerprinting surface — free at rookvpn.com/check.
Run curl online, reuse vetted command templates, and monitor URLs without installing curl locally.
Analyze phishing emails, PDFs, and installers with AI — in the browser or by forwarding mail to [email protected].
Share passwords, tokens, and recovery codes through links that expire after one view or a time limit you choose.
Clean photos and PDFs before sharing so GPS coordinates, device IDs, and author names do not leak.
Inspect JWTs, generate secure passwords, and compute checksums locally — nothing is uploaded to RookVPN.
Start with a free no-logs profile, verify with RookCheck, then upgrade when you need longer access or priority support.
Pick the hash that matches the job. Checksums and password hashes are not interchangeable.
A strong password is one you can store and an attacker cannot guess. Clever substitutions are not a scheme.
Decode shows you the JSON. Verify tells you whether the key you hold signed it. Your API still has to enforce the claims.
Identify one network, or split a parent block into several prefix lengths, without guessing the next boundary.
