The website of TestTLS.com does no longer reference any external resources. Instead we host all JS & CSS on our server. Kicking out CDNs sacrifices some speed for privacy. Do you think it is worth it?

Fixed: scanning TCP ports over #IPv6 for #TLS configuration and vulnerabilities with testtls.com is now working again. Sorry for the inconvenience.

Today we fixed an issue where expired intermediate certificates provided by a #TLS server caused testtls.com to report an "expired" chain of trust. Even if a trusted root CA certificate upheld a valid chain, like with the today expired DST Root CA X3 from Lets Encrypt

Maybe no single entity has contributed more to spreading #TLS than @letsencrypt - kudos! But simultaneously, LE is becoming a big single-point-of-failure. Did you know there are alternative CAs providing free certificates and ACME client support, like @zerosslHQ or @BuyPass?

I love how @letsencrypt is making the Internet a more secure place. But with their huge success we are centralizing #TLS #certificate issuance and creating a single point of failure. Shouldn't there be a dozen or so independent letsencrypts?

Glad to seeing a web browser finally supporting a much needed #security feature #HTTPS-only-mode: blog.mozilla.org/security/2020/… I hope that the over vendors will follow #Firefox on this feature.

Small feature but nevertheless: #download of the #certificate from your #SSL/#TLS service is now possible on testtls.com. I am embedding those using "data" URL scheme with base64 encoding; do all browsers support that?

After adding some 💕 you can now scan any TCP port for #SSL/#TLS issues on testtls.com - just enter "host:port" or "IP:port". Oh, yes #IPv6 works as well. What bad config did you find?

Big thanks to everyone giving lots of feedback during the last week via Twitter and Reddit. First improvement: scanning IPv6 targets with TestTLS is now also possible. Does that work for you as expected? Please like. If not, please comment.

Super excited to launch a new service to test the #tls #security of your server: Check out testtls.com - not just for HTTPS but many other ports. What do you think?
