How to implement cookie encryption in php, phpcookie encryption

The example in this article describes how to implement cookie encryption in php. Share it with everyone for your reference. The specific implementation method is as follows:

Copy code The code is as follows: class Cookie
{
/**
* Decrypt encrypted cookies
* *
* @param string $encryptedText
* @return string
​​*/
Private static function _decrypt($encryptedText)
{
         $key = Config::get('secret_key');
          $cryptText = base64_decode($encryptedText);
          $ivSize = mcrypt_get_iv_size(MCRYPT_RIJNDAEL_256, MCRYPT_MODE_ECB);
          $iv = mcrypt_create_iv($ivSize, MCRYPT_RAND);
          $decryptText = mcrypt_decrypt(MCRYPT_RIJNDAEL_256, $key, $cryptText, MCRYPT_MODE_ECB, $iv);
         return trim($decryptText);
}
/**
     * 加密cookie
     *
     * @param string $plainText
     * @return string
    */
Private static function _encrypt($plainText)
{
         $key = Config::get('secret_key');
          $ivSize = mcrypt_get_iv_size(MCRYPT_RIJNDAEL_256, MCRYPT_MODE_ECB);
          $iv = mcrypt_create_iv($ivSize, MCRYPT_RAND);
          $encryptText = mcrypt_encrypt(MCRYPT_RIJNDAEL_256, $key, $plainText, MCRYPT_MODE_ECB, $iv);
          return trim(base64_encode($encryptText));
}
/**
* Delete cookies
* *
* @param array $args
* @return boolean
​​*/
Public static function del($args)
{
          $name = $args['name'];
$domain = isset($args['domain']) ? $args['domain'] : null;
            return isset($_COOKIE[$name]) ? setcookie($name, '', time() - 86400, '/', $domain) : true;
}
/**
* Get the value of the specified cookie
* *
* @param string $name
​​*/
Public static function get($name)
{
          return isset($_COOKIE[$name]) ? self::_decrypt($_COOKIE[$name]) : null;
}
/**
* Set cookie
*
* @param array $args
* @return boolean
​​*/
Public static function set($args)
{
          $name = $args['name'];
          $value= self::_encrypt($args['value']);
$expire = isset($args['expire']) ? $args['expire'] : null;
$path = isset($args['path']) ? $args['path'] : '/';
$domain = isset($args['domain']) ? $args['domain'] : null;
$secure = isset($args['secure']) ? $args['secure'] : 0;
            return setcookie($name, $value, $expire, $path, $domain, $secure);
}
}
