Test TLS 1.2 Connections in Curl

When testing connections to a website using the `curl` command, it's essential to ensure that you're communicating with the server using a secure and supported version of Transport Layer Security (TLS). In this tutorial, we'll explore how to test TLS 1.2 connections in `curl`.

Initially, when attempting to connect to a website using an older version of TLS, such as TLSv1.1 or TLSv1.0, you may encounter an error message indicating that the handshake failed due to an incompatible TLS version. This is because many websites have discontinued support for these outdated versions.

To overcome this issue, we can specify the maximum supported TLS version in our `curl` command. In the example below, we'll set the maximum TLS version to 1.2, which is currently supported by most modern websites:

```

* CAfile: C:/Program Files/Git/mingw64/ssl/certs/ca-bundle.crt

* successfully set certificate verify locations:

```

By setting the `CAfile` and verifying the certificate locations, we can establish a secure connection to the website. If we were to run this command without specifying the maximum TLS version, it would return an error since the BOA website does not support older versions of TLS.

Here's an example `curl` command that sets the maximum TLS version to 1.2:

By running this command, you can verify which TLS version or cipher your website or web server supports. This is crucial in ensuring that your connections are secure and compatible with the latest security standards.
