Story is on many sires. Here is one:

PGP relies on public-private encryption key pairings that make it all but impossible for someone other than the intended recipient to read an encrypted message.
Say Sally wants to send Bob a message. Once she's done composing it, Sally uses Bob's public encryption key to encrypt the message turning it into a bunch of garbled nonsense. Then only Bob can decrypt the message using his private key.
An attacker would have to spend an impossibly long time guessing combinations to decrypt the message, making it, as we said, nearly impossible.
There are ways around decryption such as stealing private keys or hacking into a PC once the message has been decrypted. But for the most part, public-private keys offer a reasonable amount of privacy.
