iOS

Version 2.0.1

Fixed

Tunnels now use the Arqit SKA-Platform™ region configured during registration. Devices registered to a region other than the default (for example acme1) failed to connect with a "No KNode server keys" error.

Important

Crux is a new app that replaces Crux VPN. This is a new App Store listing — existing Crux VPN users will need to install Crux separately.

Added

Rebuilt from the ground up in SwiftUI, replacing the original Crux VPN client
Post-quantum tunnel keys via Arqit SKA-Platform™ — register the device in-app, agree a pre-shared key at connect time, and rotate it automatically for the life of the session
Scan a QR code to import a tunnel, including on iPad and on devices without a Neural Engine
Import and export tunnel configurations, including export of all tunnels to a zip archive
In-app logging with a redesigned log viewer for easier troubleshooting
Developer mode for exporting and importing device metadata
Proprietary licensing (EULA)

Changed

New app identity — rebranded from Crux VPN to Crux, with a new bundle identifier (com.sirius.crux)
Redesigned interface with a new icon, colour palette, and typography
Full iPad layout support
Updated to the latest Arqit SKA-Platform™ SDK
Requires iOS 18 or later

Fixed

Device registration now generates a stable device ID instead of using the device name
Resolved a race condition that prevented capital letters being typed into secure fields
Camera permissions are now requested and checked before scanning
Tunnel importer no longer rejects configurations containing unrecognised fields
