Where are primality certificates used?

hmmm, glad I read that... (not sure I learned one damn thing!)

NumberChaser, personally, I'm sorry I read that!!!!

I'm sure even most mathematicians and computer scientists cannot understand that description.

Das, SO glad that I'm not the only one who had NO IDEA what the explanation said.

The explanation seems like its at the Ph D . level . l did not get it . l will ask my Mathematician son to explain in Lay mans Terminology.

It's a little confusing but I think I got it!!
