AES加密在php5的版本中使用的mcrypt_decrypt 函数,该函数已经在php7.1后弃用了,取而代之的是openssl的openssl_encrypt和openssl_decrypt,并且代码也非常精简,下面是示例代码:
1 <?php 2 3 class Aes 4 { 5 public $key = ‘‘; 6 public $iv = ‘‘; 7 public $method = ‘‘; 8 9 public function __construct($config) 10 { 11 foreach ($config as $k => $v) { 12 $this->$k = $v; 13 } 14 } 15 16 //加密 17 public function aesEn($data) 18 { 19 return base64_encode(openssl_encrypt($data, $this->method, $this->key, OPENSSL_RAW_DATA, $this->iv)); 20 } 21 22 //解密 23 public function aesDe($data) 24 { 25 return openssl_decrypt(base64_decode($data), $this->method, $this->key, OPENSSL_RAW_DATA, $this->iv); 26 } 27 } 28 29 $config = [ 30 ‘key‘ => ‘reter4446fdfgdfgdfg‘, //加密key 31 ‘iv‘ => md5(time() . uniqid(), true), //保证偏移量为16位 32 ‘method‘ => ‘AES-128-CBC‘ //加密方式 # AES-256-CBC等 33 ]; 34 $obj = new Aes($config); 35 $res = $obj->aesEn(‘[email protected]‘);//加密数据 36 echo $res; 37 echo ‘<hr>‘; 38 echo $obj->aesDe($res);//解密
注意:要使用openssl相关函数必须要开启openssl扩展,否则程序报错
