These are just some boring update notifications from the elkemental Webiverse.
The elkement blog has recently celebrated its fifth anniversary, and the punktwissen blog will turn five in December. Time to celebrate this – with new domain names that says exactly what these sites are – the ‘elkement.blog‘ and the ‘punktwissen.blog‘ (Edit: which now – in 2020 – point to a copy of these sites elsewhere ;-))
worry about research cookies set by Twitter and Facebook, but not by ad providers, and I am also considering to remove social media sharing buttons and the embedded tweets. (Yes, I am thinking about this!)
On the websites under my control I went full dinosaur, and the server sends only non-interactive HTML pages sent to the client, not requiring any client-side activity. I now got rid of the last half-hearted usage of a session object and the respective cookie, and I have never used any social media buttons or other tracking.
So there are no login data or cookies to protect, but yet I finally migrated all sites to HTTPS.
It is a matter of principle: I of all website owners should use https. Since 15 years I have been planning and building Public Key Infrastructures and troubleshooting X.509 certificates.
But of course I fear Google’s verdict: They have announced long ago to HTTPS is considered a positive ranking by its search engine. Pages not using HTTPS will be tagged as insecure using more and more terrifying icons – e.g. http-only pages with login buttons already display a striked-through padlock in Firefox. In the past years I migrated a lot of PKIs from SHA1 to SHA256 to fight the first wave of Insecure icons.
Finally Let’s Encrypt has started a revolution: Free SSL certificates, based on domain validation only. My hosting provider uses a solution based on Let’s Encrypt – using a reverse proxy that does the actual HTTPS. I only had to re-target all my DNS records to the reverse proxy – it would have been very easy would it not have been for all my already existing URL rewriting and tweaking and redirecting. I also wanted to keep the option of still using HTTP in the future for tests and special scenario (like hosting a revocation list), so I decided on redirecting myself in the application(s) instead of using the offered automated redirect. But a code review and clean-up now and then can never hurt :-) For large complex sites the migration to HTTPS is anything but easy.
In case I ever forget which domains and host names I use, I just need to check out this list of Subject Alternative Names again:
(And I have another certificate for the ‘test’ host names that I need for testing the sites themselves and also for testing various redirects ;-))
WordPress.com also uses Let’s Encrypt (Automattic is a sponsor), and the SAN elkement.blog is lumped together with several other blog names, allegedly the ones which needed new certificates at about the same time.
It will be interesting what the consequences for phishing websites will be. Malicious websites will look trusted as being issued certificates automatically, but revoking a certificate might provide another method for invalidating a malicious website.
Anyway, special thanks to the WordPress.com Happiness Engineers and support staff at my hosting provider Puaschitz IT. Despite all the nerdiness displayed on this blog I prefer hosted / ‘shared’ solutions when it comes to my own websites because I totally like it when somebody else has to patch the server and deal with attacks. I am an annoying client – with all kinds of special needs and questions – thanks for the great support! :-)
