How does encryption work?

All Web pages that are secured on the Web use encryption to ensure that unauthorized individuals cannot read your sensitive data.  Encrypted data moves across the Internet as a string of unrecognizable numbers that cannot be decrypted into the actual information without a numeric key. This numeric key is randomly generated and agreed upon by your browser and our Web site each time you establish a connection with RCU’s secure Web pages.  This makes it possible for your computer and ours to pass encrypted data back and forth and make it recognizable only on those two computers.
