A Simple Example

Encode & Decode

<?php

use Encryption\Authcode;

$key = 'IoUwe#(#FFFsfoaHFfa';
echo $auth = Authcode::encode('String', $key), '<br>';
echo $result = Authcode::decode($auth, $key), '<br>';

<?php

$key = 'IoUwe#(#FFFsfoaHFfa';
echo $auth = Encryption\Authcode::encode('String', $key), '<br>';
echo $result = Encryption\Authcode::decode($auth, $key), '<br>';

Only correct key can decode

<?php
$key = 'IoUwe#(#FFFsfoaHFfa';
echo $auth = Encryption\Authcode::encode('String', $key), '<br>';
echo $result2 = Encryption\Authcode::decode($auth, 'otherKey'), '<br>';    # Can't get 'String'

Use expiry

$key = 'IoUwe#(#FFFsfoaHFfa';
echo $auth = Encryption\Authcode::encode('String', $key, 10), '<br>';
sleep(11);
echo $result = Encryption\Authcode::decode($auth, $key), '<br>';    # Can't get 'String'

echo $auth = Encryption\Authcode::encodeRemainEqualsigns('String', $key), '<br>';    # has '='
echo $result = Encryption\Authcode::decode($auth, $key), '<br>';
