Description:
------------
When I use:
 $method = 'id-aes128-GCM';
the openssl_decrypt returns false.

However, when I use a different cipher method like 'AES-128-CBC' (like used in 011.phpt) it returns the input string (correct behavior).

So I want to use aes128-GCM because GCM mode is recommended for authenticated encryption.





Test script:
---------------
<?php
error_reporting(E_ALL);
$data = '1234567890ABCDEF';
$method = 'id-aes128-GCM';
$password = 'dCoD........Eu39';
$iv_size = openssl_cipher_iv_length($method);
$iv = openssl_random_pseudo_bytes($iv_size);
$encrypted = openssl_encrypt($data, $method, $password, $options = 0, $iv);
$output = openssl_decrypt($encrypted, $method, $password, $options = 0, $iv);
echo in_array($method, openssl_get_cipher_methods()) ? $method."\n" : "";
echo var_dump($encrypted);
echo var_dump($output);
exit(0);

Expected result:
----------------
id-aes128-GCM
string(24) "lIn8CH5BBWWR/q1WdSf7Pw=="
string(16) "1234567890ABCDEF"

Actual result:
--------------
id-aes128-GCM
string(24) "lIn8CH5BBWWR/q1WdSf7Pw=="
bool(false)
