One you have created your GPG

One you have created your GPG have a look at the FREE root signing authority CACERT: http://www.cacert.org

Once you are verified you can get your key signed by them for FREE of course.

They all provide a range of other keys for such as S/MIME, SSL etc.. (all for free).

Merci Marcel !

If you want to decode Evolution's signed and encrypted mail in KMail, you can also look at this page:
http://kmail.kde.org/kmail-pgpmime-howto.html

This will teach you how to install a kmail plugin to decode PGP-MIME mails (such as Evolution's), and use gpg-agent to remember your passphrase (for a limited amount of time)
With the plugin, you can also send PGP-MIME messages.
Very useful

By the way, all the software required on this page is available as RPM for Fedora and Mandrake at least, and I'm pretty sure there are Debian packages available too.
Isn't it merveilleux ? ;-)

Bonjour Marcel, As all your articles, this latest is excellent and is really good to make people realize that now than ever before it is crucial to secure our data since the excesses of western government surveillance infringe our private life. The French government plans to pass a bill that would allow ISPs to read e-mails of their supposed "sensitive" clients.

So I generated a key pair with gnupg and configured a year ago my favourite e-mail client, KMail from the KDE, so that I can encrypt and decrypt "sensitive" e-mails. It worked fine until recently. When I want to sign or decrypt an e-mail, it asks for my passphrase. Until recently everything worked smoothly but now neither KMail nor the KGpg nice utility seems to recognize my passphrase. I changed it and it is still the same. I'm sure the passphrase is right since it works when I encrypt and decrypt files from the console command line. Do you have any clue? I am getting mad checking everything. If you could help me I would be very grateful.

Thanks again for your tremendous work.
Au revoir. Patrick

Linux Management with Red Hat Satellite: Measuring Business Impact and ROI

Linux has become a key foundation for supporting today's rapidly growing IT environments. Linux is being used to deploy business applications and databases, trading on its reputation as a low-cost operating environment.

As Linux grows in importance in terms of value to the business, managing Linux environments to high standards of service quality — availability, security, and performance — becomes an essential requirement for business success.

They need agility, flexibility, convenience, ROI, and control.

Stackato private Platform-as-a-Service technology from ActiveState extends your private cloud infrastructure by creating a private PaaS to provide on-demand availability, flexibility, control, and ultimately, faster time-to-market for your enterprise.
