How to compress/encrypt/convert large string into a small string?

Posted: 03 Nov 2010 12:15 AM PDT

I am developing an application which requires activation over phone. For this process, the program generates an ID (which comprises of the product key and motherboard serial number) which the user tells to our representative.

The problem which I am facing is that the ID which is generated by the program is very large (about 80 characters), and it is obviously very difficult for the user to dictate those 80 characters to our representative. :(

Is there any method to encrypt or compress those 80 characters into a set of small string of about 40 - 45 chars ?

We're developing this software over the .net framework.
