Dirk’s Slide Presentation on GPG - Act 1: (43 slides)

Dirk Bartley explained GPG, the Gnu Privacy Guard project.
This is an Open Source data encryption software project.

The presentation covered the concepts and use of GPG to
encrypt and digitally sign files. The objective was to
familiarize the attendees with using GPG from basic concept
to the command line interface. He started out by covering
the basics from his previous encryption related KLUG
presentations. He has already covered SSH, Kerberos, & SSL!
We heard about ciphers, keys, cryptoanalysis, and algorithims.
He answered questions throughout the presentation and worked

hard to help those that were trying to grasp the concepts.

Dirk talked about symmetric and asymmetric encryption and
decryption, data signing, asymmetric key generation, key
management, and even key parties. He discussed various
related authentication and security considerations.

The second half of Dirk’s GPG presentation (next week) will
cover the concepts and use to encrypt attached e-mails.

Open Source GNU Privacy Guard is distributed by the Free
Software Foundation. Richard Stallman founded the GNU
Project in 1984.

[From the GnuPG FAQ page]
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.

Some people say you only need encryption if you have something
to hide. Others say that you are entitled to privacy and to be
secure in your personal computer originated communication.

We had a VIP in attendance tonight. Dirk’s father, retired WMU
Communications Professor Lynn Bartley, witnessed his son’s
passion for the Linux OS, Open Source software, and teaching

his knowledge to others. Dirk served dutifully as KLUG Chair
for two terms of office.
