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;
