Security library Loading Error

I downloaded 1.7.1 and there is no Security class in that version. That is why you are getting that error. It is only a helper.

Is possible to use helper ?

Yes, because there is a security helper, but you were trying to load a security library also according to your code. That's why you are getting an error because you are trying to load a class that does not exist.
