Complete example of php aes encryption algorithm, phpaes Encryption Algorithm
This example describes the AES Encryption Algorithm of PHP. We will share this with you for your reference. The details are as follows:
<?phpclass MCrypt { private $hex_iv = '00000000000000000000000000000000'; # converted JAVA byte code in to HEX and placed it here private $key = 'U1MjU1M0FDOUZ.Qz'; #Same as in JAVA function __construct() { $this->key = hash('sha256', $this->key, true); //echo $this->key.'<br/>'; } function encrypt($str) { $td = mcrypt_module_open(MCRYPT_RIJNDAEL_128, '', MCRYPT_MODE_CBC, ''); mcrypt_generic_init($td, $this->key, $this->hexToStr($this->hex_iv)); $block = mcrypt_get_block_size(MCRYPT_RIJNDAEL_128, MCRYPT_MODE_CBC); $pad = $block - (strlen($str) % $block); $str .= str_repeat(chr($pad), $pad); $encrypted = mcrypt_generic($td, $str); mcrypt_generic_deinit($td); mcrypt_module_close($td); return base64_encode($encrypted); } function decrypt($code) { $td = mcrypt_module_open(MCRYPT_RIJNDAEL_128, '', MCRYPT_MODE_CBC, ''); mcrypt_generic_init($td, $this->key, $this->hexToStr($this->hex_iv)); $str = mdecrypt_generic($td, base64_decode($code)); $block = mcrypt_get_block_size(MCRYPT_RIJNDAEL_128, MCRYPT_MODE_CBC); mcrypt_generic_deinit($td); mcrypt_module_close($td); return $this->strippadding($str); } /* For PKCS7 padding */ private function addpadding($string, $blocksize = 16) { $len = strlen($string); $pad = $blocksize - ($len % $blocksize); $string .= str_repeat(chr($pad), $pad); return $string; } private function strippadding($string) { $slast = ord(substr($string, -1)); $slastc = chr($slast); $pcheck = substr($string, -$slast); if (preg_match("/$slastc{" . $slast . "}/", $string)) { $string = substr($string, 0, strlen($string) - $slast); return $string; } else { return false; } } function hexToStr($hex) { $string=''; for ($i=0; $i < strlen($hex)-1; $i+=2) { $string .= chr(hexdec($hex[$i].$hex[$i+1])); } return $string; }}$encryption = new MCrypt();echo $encryption->encrypt('123456') . "<br/>";echo $encryption->decrypt('tpyxISJ83dqEs3uw8bN/+w==');?>
