Simple encoding/decoding of data and hash validation using a shared secret.

Usage

1. Initialization

// Composer autoloader
require_once 'vendor/autoload.php';

use nurtext\SignedRequest;

// Set a shared secret
SignedRequest::setSharedSecret('my shared secret');

2. Generating a signed request

// Encode and hash the data
$signedRequest = SignedRequest::generate(array('hello' => 'world'));

// Debug output
var_dump($signedRequest);

3. Verifying a signed request

// Just verify, don't return the parsed data
var_dump(SignedRequest::verify($signedRequest));

4. Verifying and parsing a signed request in a single call

// Verify and return data if verification succeeds
var_dump(SignedRequest::parse($signedRequest));

• PHP >= 5.1.2
