Using the -verbose parameter gives you the ability to see the TLS handshake and get the output sent to standard out. In order to override a system default and set a supported (D)TLS or SSL protocol version to the Enabled state, create a DWORD registry value named 'Enabled' with a non-zero value, and a DWORD registry value named 'DisabledByDefault' with a value of zero, under the corresponding version-specific subkey. This code here uses curl with the parameters -tlsv1.1 -tls-max 1.1, which will force the max TLS protocol version to 1.1. 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 curl to go just that.
