A lot of people would like some reassurance that the people who they are communicating
with are who they say they are. One of the ways to verify this is by using some type
of cryptographic mechanism. The one I use is an
open source program called gpg.
This scheme makes use of public and private keys to ensure that only authorized parties are
able to make use of files sent to them and that the party you are communicating with is
who you think they are.
