Semi prime numbers are numbers that are the product of 2 prime numbers.

They are incredibly usefull and I can't beleive that this thread has been up for this long without somebody giving the use.

Semi prime numbers make up the basis of how secure web sites work. Exchanging really large semi prime numbers is how secure website are secure without a key having to be sent in a non public manor. I will try and find my texts on the subject and post something better.
