Install this root certificate on unmanaged devices to trust TLS services issued by the CQRE internal certificate authority.
Install the root certificate into the system trust store. Use the intermediate certificate only when a specific client or tool asks for it separately.
After downloading, double-click the certificate and add it to the system trust store.
On iOS / iPadOS you can AirDrop or email the file, install it via Settings ➝ General ➝ VPN & Device Management, then enable full trust.
On Android, open the file and choose “Install certificate” → “VPN and apps”.
For Linux, place the file in /usr/local/share/ca-certificates/ and run
sudo update-ca-certificates.
Combined certificate-chain bundles are intentionally not published here because import support is inconsistent across operating systems.
