In this article I'll help you get started with GnuPG, the GNU Privacy Guard. Instead of writing another GnuPG manual, I'll teach you how to generate your first keypair, sign/verify files and encrypt/decrypt files.

If you don't know what GnuPG is, this description from the official website will clear things up for you.

GnuPG is the GNU project's complete and free implementation of the OpenPGP standard as defined by RFC2440 . GnuPG allows to encrypt and sign your data and communication, features a versatile key managment system as well as access modules for all kind of public key directories.

Getting GnuPG

If you're using a Linux distribution, gpg is most likely already installed for you. If not, you can use the package manager included with your distribution to install the gnupg package. Windows users can check out the GnuPG website, but I recommend them to install a free operating system such as Ubuntu.
