Dirk Bartley explained GPG, the Gnu Privacy Guard project. This is an Open Source data encryption software project. http://www.gnupg.org
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. http://www.gnu.org/
[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. http://www.gnupg.org/(en)/documentation/faqs.html
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.
