Web Cryptography API Examples

Live Table: https://diafygi.github.io/webcrypto-examples/

I couldn't find anywhere that had clear examples of WebCryptoAPI, so I wrote examples and made a live table with them. Pull requests welcome!

Info on bit length and complexity

From it you may gather that using 256 bit ECDSA key should be enough for next 10-20 years.

README

Services declared as oneshot are expected to take some action and exit immediatelly (thus, they are not really services, no running processes remain). A common pattern for these type of service is to be defined by a setup and a teardown action.

Let's create a example foo service that when started creates a file, and when stopped it deletes it.

Define setup/teardown actions

Create executable file /opt/foo/setup-foo.sh:

<?php
$key = "<API Key>";
$from = "info@example.com";
$to = "dave@example.com";


if ($_SERVER['REQUEST_METHOD'] == 'POST') {
	if(isset($_POST['timestamp']) && isset($_POST['token']) && isset($_POST['signature']) && hash_hmac('sha256', $_POST['timestamp'] . $_POST['token'], $key) === $_POST['signature'])
	{
		if($_POST['event'] == 'complained') {
