I'm not sure why you're linking to that site?

The question isn't whether the NSA are able to do SHA-1 collisions
(which I think everybody assumes that they can, albeit expensively), but
whether they can create certificates.  The jury is out on that one, and
many people think that it's not a thing (yet) (with certificates with
the recommended entropy in serial numbers and dates).

It will almost certainly be bogus (now).  Next year, perhaps not.
