Worried about an NSA ChainOfFools/CurveBall attack? There are lots of moving parts. Test your system.

The pro-patch-now argument generally goes something like this: Everybody is recommending that you install the patches to protect against the Crypto bug — almost all of the major security folks, the researchers, the big online sites, your local news station, your congresscritter, your neighbor’s nine-year-old, even the bleeping NSA. It’s a little patch. Why not just install it and be done with it?
