KLUG Weekly Meeting Notes

Tuesday, November 22, 2005



Presented by Dirk Bartley!

With two SVGA projectors, a detailed outline, and the details on
four GPG e-mail encryption and authentication… Dirk Bartley
used the KLUG LTSP boxes, creating a table wide network (TWN)
for a multiple platform network, to show us how it all works.

Dirk Bartley demonstrated GPG, the Gnu Privacy Guard project.
This presentation covered the concepts and use of GPG to encrypt
attached emails as well as to prove that the email was sent from

the possessor of the appropriate private key. The objective was to
familiarize the audience with using GPG from open email clients
as well as Microsoft Outlook.

Dirk had several points he wanted to emphasize in review of the
initial GPG presentation. He clearly described the difference
and purpose of encryption and signing with signatures! He also
wanted to add a big picture usage reference.

Why should I encrypt my mail? I'm not doing anything illegal!
You should encrypt your e-mail for the same reason that you don't
write all of your correspondence on the back of a post card. E-mail
is actually far less secure than the postal system. With the post

office, you at least put your letter inside an envelope to hide it
from casual snooping. Take a look at the header area of any e-mail
message that you receive and you will see that it has passed through
a number of nodes on its way to you. Every one of these nodes presents
the opportunity for snooping. Encryption in no way should imply illegal
activity. It is simply intended to keep personal thoughts personal.

Crime? If you are not a politician, research scientist, investor,
CEO, lawyer, celebrity, libertarian in a repressive society,
investor, or person having too much fun, and you do not send
e-mail about your private sex life, financial/political/legal/scientific
plans, or gossip then maybe you don't need PGP, but at least realize
that privacy has nothing to do with crime and is in fact what keeps
the world from falling apart. Besides, PGP is FUN.
You never had a secret decoder ring? Boo!

Theodore Thunder Thunderbird Enigmail
Kevin Keller Kmail KGPG
Edgar Evans Evolution GNU Privacy Assistant
Owen Outdone Outlook GPG Relay

The latest version of Enigmail is 0.93.0, working with Thunderbird 1.0.x
and Mozilla 1.7.x. Enigmail is an extension to the mail client of
Mozilla / Netscape and Mozilla Thunderbird which allows users to access
the authentication and encryption features provided by GnuPG (see
screenshots). Enigmail is open source and dually-licensed under the GNU
General Public License and the Mozilla Public License.

KGPG is a simple, free, open source KDE frontend for GPG with Kmail.

GnuPG stands for GNU Privacy Guard and is GNU's tool for secure
communication and data storage. It can be used to encrypt data and to
create digital signatures. It includes an advanced key management
facility and is compliant with the proposed OpenPGP Internet standard
as described in RFC 2440. As such, it is aimed to be compatible with

PGP from NAI, Inc.

GPGrelay is, as indicated by its name a local relaying server.
It works completely transparent for your Email-Client as well as for
the remote Server. Now, if you want to send emails encrypted, GPGrelay
encrypts them and sends the encrypted mail to the SMTP-Server.
If you receive an encrypted mail, GPGrelay does the decryption for you –
so your Email-Client never sees any encrypted mails, which is quite a

nice feature when your Email-Client (like Outlook Express) is not capable
of handling those mails.
