Gibberish AES, a PHP Implementation

See Gibberish AES javascript encryption library, https://github.com/mdp/gibberish-aes

An important note: The complementary JavaScript project Gibberish AES has been deprecated, see mdp/gibberish-aes#25
Consider finding alternative PHP and JavaScript solutions.

This class is based on initial code proposed by nbari at dalmp dot com http://www.php.net/manual/en/function.openssl-decrypt.php#107210

Live Demo

Requirements:

php >= 7.1

openssl and mbstring module

Usage Example:

echo '<br />';

// This is a secret pass-phrase, keep it in a safe place and don't loose it.
$pass = 'my secret pass-phrase, it should be long';
echo '$pass = '.$pass;
echo '<br />';
// The string to be encrypted.
$string = 'my secret message';
echo '$string = '.$string;
echo '<br />';
echo '<br />';

// The default key size is 256 bits.
$old_key_size = GibberishAES::size();

echo 'Encryption and decryption using a 256-bit key:';
echo '<br />';
GibberishAES::size(256);
// This is the result after encryption of the given string.
$encrypted_string = GibberishAES::enc($string, $pass);
// This is the result after decryption of the previously encrypted string.
// $decrypted_string == $string (should be).
$decrypted_string = GibberishAES::dec($encrypted_string, $pass);
echo '$encrypted_string = '.$encrypted_string;
echo '<br />';
echo '$decrypted_string = '.$decrypted_string;
echo '<br />';
echo '<br />';

echo 'Encryption and decryption using a 192-bit key:';
echo '<br />';
GibberishAES::size(192);
$encrypted_string = GibberishAES::enc($string, $pass);
$decrypted_string = GibberishAES::dec($encrypted_string, $pass);
echo '$encrypted_string = '.$encrypted_string;
echo '<br />';
echo '$decrypted_string = '.$decrypted_string;
echo '<br />';
echo '<br />';

echo 'Encryption and decryption using a 128-bit key:';
echo '<br />';
GibberishAES::size(128);
$encrypted_string = GibberishAES::enc($string, $pass);
$decrypted_string = GibberishAES::dec($encrypted_string, $pass);
echo '$encrypted_string = '.$encrypted_string;
echo '<br />';
echo '$decrypted_string = '.$decrypted_string;
echo '<br />';
echo '<br />';

// Restore the old key size.
GibberishAES::size($old_key_size);
