= Secure hello world example
|
|
|
|
To try this example, you need GNU `make` and `git` in your PATH.
|
|
|
|
To build and run the example, use the following command:
|
|
|
|
[source,bash]
|
|
$ make run
|
|
|
|
Then point your browser to https://localhost:8443
|
|
|
|
You will be greeted by a security message. You can ask for more
|
|
information and ultimately accept to access localhost. This is
|
|
due to the example using a self-signed certificate.
|
|
|
|
Recent browsers will communicate using HTTP/2. Older browsers
|
|
will use HTTP/1.1.
