GnuPG does two things: encryption, and authentication.. The authentication
provides a digital signature, which serves the same purpose as a traditional
signature: proving who someone is. Actually, they're MUCH better than
traditional signatures, when used correctly.
GnuPG does both of those things by using keypairs: public and private keys.
Everyone has a secret key, and then one which they publish. If you have the
public key of someone else, you can check everything signed by that person
against their public key, and so you know that the person who wrote it is who
they say they are.
I'm not sure how you would use this for preventing spam, though. Presumably,
you would only accept email from people whose public keys you have. To me,
that's like mining your garden: it might keep people away, but it'll keep
everyone away, and it makes it tough to enjoy your garden, too. Maybe I
don't fully understand though.
