Improved security with HSTS

ohdear.app

In a new post at the Oh Dear blog, there's a good explanation how HSTS improves security.

HSTS stands for HTTP Strict Transport Security. It's a mechanisme that allows a website to signal that it should only be reached via HTTPS - the encrypted HTTP - instead of the plain text HyperText Transfer Protocol.

The end of Extended Validation certificates

ma.ttias.be

Mattias Geniar argues that you shouldn't buy extended validation certificates.

You know those certificates you paid 5x more for than a normal one? The ones that are supposed to give you a green address bar with your company name imprinted on it? It's been mentioned before, but my take is the same: they're dead.

Extended Validation Certificates are Dead

www.troyhunt.com

In a new blogpost Troy Hunt explains why you shouldn't bother buying an EV certificate anymore.

That's it - I'm calling it - extended validation certificates are dead. Sure, you can still buy them (and there are companies out there that would just love to sell them to you!), but their usefulness has now descended from "barely there" to "as good as non-existent". This change has come via a combination of factors including increasing use of mobile devices, removal of the EV visual indicator by browser vendors and as of today, removal from Safari on iOS

Oh Dear! Website and SSL Monitoring Application Is Now Live

Together with Mattias I've been working on Oh Dear! for the last couple months. We launched it last week. If you want to try it out, just register and you'll get a trial period of 10 days. No credit card is needed.

I plan on writing a few technical posts on the whole project in the next couple of months. Right now you can already read this excellent article written by Paul Redmond about what Oh Dear! can do for you.

What differentiates Oh Dear from other uptime monitoring solutions, in my opinion, is the mixed content detection and SSL certificate monitoring. The web is moving to HTTPS, and your site’s availability can be affected by modern browsers when things go awry with your certificate.

What web developers should know about SSL but probably don't

In 2015 web developers understand more about SSL than they ever have. If you read Hacker News you should know: What about the rest?

10 Reasons To Use HTTPS

Today, however, there are more reasons than ever to switch to HTTPS — even for a news site, corporate site, or any site that doesn’t consider itself at the top of the security food chain. HTTPS adoption grew 80% last year alone, much faster than previous years, but we’re still very far from encryption being the norm.

If you’re not convinced HTTPS is right for you, or need ammo to convince your peers and bosses, here are 10 good reasons to go HTTPS.

certificatechain.io: an online tool to download intermediate ssl certificates

When installing an SSL certificate on your server you should install all intermediate certificates as well. If you fail to do so, some browsers will reported “untrusted” warnings for your site like this one.

untrusted

Searching and downloading those intermediate certificates can be a hassle.

Today my colleagues at Spatie and I launched certificatechain.io. This online tool helps you download all intermediate certificates. Just paste or upload your certificate and you'll get a file containing the entire trust chain that you can install on your server.

The site is built with Laravel 5 and uses the SSL certificate chain resolver we made last month.

SSL certificate chain resolver

All operating systems contain a set of default trusted root certificates. But CAs usually don't use their root certificate to sign customer certificates. Instead of they use so called intermediate certificates, because they can be rotated more frequently.

A certificate can contain a special Authority Information Access extension (RFC-3280) with URL to issuer's certificate. Most browsers can use the AIA extension to download missing intermediate certificate to complete the certificate chain. This is the exact meaning of the Extra download message. But some clients (mobile browsers, OpenSSL) don't support this extension, so they report such certificate as untrusted.

A server should always send a complete chain, which means concatenated all certificates from the certificate to the trusted root certificate (exclusive, in this order), to prevent such issues. Note, the trusted root certificate should not be there, as it is already included in the system’s root certificate store.

This tools downloads all the intermediate certificates in the trust chain.
