phalcon: crypt-encrypt/decrypt用法

phalcon：crypt加密与解密

可以在入口文件index.php进行配置，也可以不配置：

$di->set('crypt', function(){
    $crypt = new \Phalcon\Crypt();
    return $crypt;
}, true);

或者：

$di['crypt'] = function(){
   $crypt=new \Phalcon\Crypt();
   return $crypt;
};

关于调用：
$this->crypt;
或者
$this->di['crypt'];
或者
$this->di->crypt;

　　

加密解密代码：

        $key = "le password";
        $password = "this is a secret text";

            //加密
            $crypt = new \Phalcon\Crypt();
            $encrypted = $crypt->encrypt($password, $key);
            echo $encrypted;

            //解密
            $crypt = new \Phalcon\Crypt();
            $encrypted = $crypt->encrypt($password, $key);
            //
            $password = $crypt->decrypt($encrypted, $key);
            echo $password;

　　

64位的加密解密方便url传输：

      $crypt = new \Phalcon\Crypt();
       // $crypt->setCipher('blowfish');
        $key = "le password";
        $password = "this is a sicret text";

        //加密
        $encrypted = $crypt->encryptBase64($password, $key);
        echo $encrypted;

        echo "<br>";

       //解密
        $password = $crypt->decryptBase64($encrypted, $key);
        echo $password;
