Server Security

TLS/SSL Cryptography

For the security of your connection and data, this server requires that your browser supports the cryptographic protocol TLS v1.2 or higher. Older browsers and operating systems such as Internet Explorer 10, Safari 6, and Android 4.3 or below will probably not work. Currently, this server/site scores a maximum A+ on the SSL Server Test suite produced by Qualys SSL Labs.

Content Security Policy

This site uses a strict content security policy (CSP). If you find some pages are not appearing correctly you may have installed a buggy browser extension which is trying to inject something into this site's pages. Try disabling any browser extensions one at a time to find the culprit (or disable them all and enable one at a time - you get the idea).

Post-Quantum Cryptography

Post-Quantum Cryptography (PQC) is used to secure management connections to this server, but is not currently employed for the web server itself. PQC will be enabled on the web server at the earliest opportunity.
