Ever need to set your web server a specific protocol version of TLS for web servers and need a quick way to test that out to confirm? Let’s check out how to use
curlto go just that.
This code here uses
curlwith the parameters
--tlsv1.1 --tls-max 1.1, which will force the max TLS protocol version to 1.1. Using the
--verboseparameter gives you the ability to see the TLS handshake and get the output sent to standard out.
Also, check the comments for a very helpful addendum.
I should note that cURL is built into Windows 10 as of v1803, and it’s been a part of MacOS and Linux for a long, long time.
