In today's time of rampant information crimes, including identity theft, security is more important to the average computer user than ever. This tutorial shows how you can use GnuPG to secure and verify data on your Linux box.

"...We are pleased to announce the availability of a new stable GnuPG-2 release: Version 2.0.9 -- The GNU Privacy Guard (GnuPG) is GNU's tool for secure communication and data storage. It can be used to encrypt data, create digital signatures, help authenticating using Secure Shell and to provide a framework for public key cryptography.

"...The GNU Privacy Guard (GnuPG) is GNU's tool for secure communication and data storage. It can be used to encrypt data, create digital signatures, help authenticating using Secure Shell and to provide a framework for public key cryptography. It includes an advanced key management facility and is compliant with the OpenPGP and S/MIME standards..."

The GNU Privacy Guard (GnuPG) allows you to encrypt, decrypt, sign, and verify communications and data, as well as create and manage the keys needed for these tasks. It is a full, open source implementation of the OpenPGP Standard (RFC2440) and is integrated into many Linux applications ranging from clipboard applets to instant messaging clients.

Seahorse is a Gnome front end for GnuPG - the Gnu Privacy Guard program. It is a tool for secure communications and data storage. Data encryption and digital signature creation can easily be performed through a GUI and Key Management operations can easily be carried out through an intuitive interface.

"Hello! We are pleased to announce the availability of a new stable GnuPG-1 release: Version 1.4.9. This is a maintenance release to fix a possible vulnerability introduced with 1.4.8. [...] Note that this version is from the GnuPG-1 series and thus smaller than those from the GnuPG-2 series..."

GnuPG is the GNU project's complete and free implementation of the OpenPGP standard as defined by RFC4880 . 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.

Performing GnuPG functions from Vim is actually pretty helpful if you work heavily with both applications on a regular basis. I was recently looking for a simple way to both word wrap and clearsign various text files within Vim, and found just what I was looking for.

"Now that Emacs has encryption functions built-in (previously, an external library had to be added), you can use GnuPG to keep all your sensitive data secret..."
