A Simple Example

Encode & Decode

<?phpuseEncryption\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'

Encode remain equal signs

python without '=' base64.b64decode() can't decode

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