Windows OpenSSL binaries


Every now and then I need to use openssl on windows, and I always struggle finding a good set of prebuilt binaries. For a long time I have been fine with a very old version of openssl built back in 2008 – but recently I needed to use some newer features so I had to find a more recent build of OpenSSL.

After some googling I found these

They work wonders, and he builds a lot of flavors.

The command I wanted to use was

openssl s_client -connect {}:443 -servername {}

Which can be used to view certificate chain used by a web server.
