Certificates

These are the currently in-use SSL/TLS certificates.

IMPORTANT: ADMIN-ONLY. Regular end-users should NOT have to change any settings regarding certificates. Use a modern browser.

WARNING: It's recommended to trust your browser vendor's root certificates.
Only trust specific certificates if there's no altenative (eg, if you have to manage your own trust store).
Even in this scenario, please trust the root certificates in preference to endpoint certificates.

Please keep browsers, trust stores, and operating system updated according to the vendors recommended update policy.
