I am following the ROS 2 Humble documentation and it is required openssl v1.1.1t. In the official website I cannot find that versione cause EOL. How can I install it?

I found a good guide here to install openssl: https://github.com/openssl/openssl/blob/master/NOTES-WINDOWS.md

  • $\begingroup$ This is a bit of a link only answer. Whilst the repo is unlikely to disappear (as it is the OpenSSL repo, after all), it might be worth quoting the relevant part of the read me in your answer. $\endgroup$ Commented Apr 30 at 11:15
