Security & Verification
How to confirm an AirLink build is genuine, and how to reach us about security matters.
This page explains how to confirm that an AirLink build is genuine, and how to reach us if you ever have a security question.
Signed Windows builds
AirLink installers for Windows are digitally signed, so Windows shows the publisher as AIRLink. A newly released signed app can briefly show a Windows SmartScreen prompt while it builds reputation — this is normal for new software and goes away over time. We explain it in more detail on the Support page.
Verify your download
For the builds we host directly — Windows and Android — we publish a SHA-256 checksum so you can confirm the file you downloaded is exactly the one we released:
To check it on Windows, open PowerShell in the download folder and run Get-FileHash .\AIRLinkVPN-Setup-x64.exe -Algorithm SHA256; on macOS or Linux, run shasum -a 256 AIRLink.apk. If the value matches the one above, the file is intact. The iOS and macOS apps come from the App Store, where Apple signs every build, so no manual check is needed.
Get in touch
If a security tool has flagged an AirLink build, or you have any other security question, we're glad to help — just include the file name and, if you have it, the SHA-256.
