  Oh ok.. thank you! (Somehow I'd never heard of that.)

    Cool, that means that browser developers and web server developers are doing their jobs halfway right :)

      hehe I guess so. Was a bit shocked to read SSL is deprecated! Still had that on my "Things to learn about one day" list! ...Ah, I did get this error trying to curl something earlier today "error:1407742E:SSL routines:SSL23_GET_SERVER_HELLO:tlsv1 alert protocol version" - seems my computer hasn't heard of it either.

        SSL and TLS are really the same protocol, except that newer versions are called TLS. Many software stacks still refer to both as SSL, but these days we only use TLS. My understanding is that the renaming was mostly politics between Microsoft, Netscape, and the IETF in the 90s.
