WordPress Client Certificate Authentication

Client Certificate Authentication is possible for the CAcert Blog for some time. Now, the code was put into an own plugin and published to the wordpress plugin directory. You can also install the plugin directly from your wordpress admin interface to use it in your own blog.

Acknowledgements: This plugin is based on the HTTP Authentication plugin by Daniel Westermann-Clark. Ideas taken from Dan B.’s implementation for client certificate authentication.

Upgrade of lists server [Update: done]

During the last hours, the CAcert mailing list server was upgraded to the latest OS realease Debian Wheezy.

Please let us know, if you experience any problems.

Blog update

The CAcert Blog (incl. its system) has been upgraded to recent software versions. With this also a new Theme had to be created to be compatible with the current version of the blog software.

Please let me know, if anything was broken by the upgrade or anything does not work for you as expected.

Maintenance / Changes infrastructure

[Update: finished.] I will begin with the work now 2012-04-01 00:00 UTC. Infrastructure e.g. email, wiki, blog, lists will be unavailable during the time. The CAcert website along with all critical systems are not “infrastructure” and will not be affected.

I am planning to work on infrastructure again this weekend (2012-03-31) and downtimes may occur. Our host is low on disk space so I need to do some restructuring. A larger downtime may be involved.

Currently, each virtual host has its own logical volume (LVM). They will be consolidated into one. During the move and resizing I think I will not get around shutting down all infrastructure services.

I will send out a notice before I begin the work.
Sorry for any inconvenience.


I am currently continuing the work until 2012-03-26 07:00 UTC. The following services may be effected (the other services have been migrated already):

  • email
  • lists
  • emailout
  • board
  • translingo

I am working on infrastructure systems. During the next 6 hours the following services may be down as they are moved to another server:

* bugs
* irc
* webmail
* wiki
* email
* cats
* lists
* issue
* emailout

The following services have been shut down:

* dupes
* forum
* logging
* paypal
* test2

CAcert AGM, New Board and Annual Report

On 2010-01-30 CAcert held its Annual General Meeting. Minutes will be published soon on the wiki.

A new board was elected and positions were assigned during 2010-02-02 board meeting. We are happy to announce the new CAcert board formed by

  • Lambert Hofstra (President)
  • Daniel Black (Vice President)
  • Ernestine Schwob (Treasurer)
  • Mark Lipscombe (Secretary and continuing as Public Officer)
  • Nick Bebout (Member)
  • Mario Lipinski (Member)
  • Ian Grigg (Member)

During the AGM CAcert’s annual report (PDF) was presented and accepted by the membership. It shows many things happened at CAcert during the last year and is worth reading to get an impression of CAcert’s progress during the last time.

A big thank you to all people volunteering and helping to achieve this successful result. CAcert is dependent on many volunteers and is looking forward for your help to achieve such a good result for the coming year.
