Posted by jpluimers on 2018/03/07

It was fitting to bump into [WayBack] Packet Sender is a good tool when debugging protocols…” Written by Dan Nagle… – Lars Fosdal – Google+ on the day presenting [WayBack] Conferences/Network-Protocol-Security.rst at master · jpluimers/Conferences · GitHub

It also means that libssh2-delphi is getting a bit more love soon and will move to github as well after a conversion from mercurial.

Some of the things I learned or got confirmed teaching the session (I love learning by teaching):

badssl.com

Posted by jpluimers on 2018/01/11

I wish I had bumped into this when it got released in 2015: [WayBackbadssl.com hosted in the cloud and maintained by two people from Google and Mozilla.

Where ssllabs.com is for checking server-side certificates, this one is for checking clients against many, many (did I already write MANY?) server side configurations both good (with a varying set of security settings like cyphers and key exchanges) and bad.

One of the bad ones is expired.badssl.com which your clients should not be able to connect to without throwing a big error.

Sources are at [WayBack] GitHub – chromium/badssl.com: Memorable site for testing clients against bad SSL configs.

Before using, please read their

Disclaimer

badssl.com is meant for manual testing of security UI in web clients.

Most subdomains are likely to have stable functionality, but anything could change without notice. If you would like a documented guarantee for a particular use case, please file an issue. (Alternatively, you could make a fork and host your own copy.)

badssl.com is not an official Google product. It is offered “AS-IS” and without any warranties.
