How to setup OTR encryption in Pidgin

Writing proper howtos is so hard and time consuming. Copy/pasting them from other sites is so much easier. \o/

This time we ripped this tutorial from great website https://securityinabox.org Check it out for more articles and howtos about privacy and encryption

REMEMBER! Most of the settings in this tutorial, as well as general way of using OTR can be applied to any chat program supporting off-the-record encryption

How to Use OTR to Initiate a Secure Messaging Session in Pidgin

About Pidgin and OTR

Both your correspondent and yourself must configure the OTR plugin before you can enable private and secure Instant Messaging (IM) sessions. OTR plugin will automatically detect when both parties have installed and properly configured the OTR plugin.

Note: If you request a private conversation with a friend who has neither installed nor configured OTR, it will automatically send a message explaining how they can obtain the OTR plugin.

Keysigning party under the bridge – Wednesday May 6th

GPG is the free implementacion of the Pretty Good Privacy system. This allows you to sign and encrypt messages to other people, and if we sign each other our keys you can also verify that the person you know is who actually wrote the email.some color keys

Send your public key by mail to anybody from the #slug, and come over next Wednesday to get more people to sign it.

Encryption is not as complicated as it sounds, check out this howto for making your own gpg key in case you don’t have one yet, this video tutorial for using Thunderbird Enigmail plugin, and this other tutorials for GPG.

What you can bring to the party:

  • Little pieces of paper with your gpg key information (specially your fingerprint).
  • Fruits, tea, juice.
  • You don’t need to take your computer
  • You don’t need to take your id (Yes, in all the howtos talks about the ID but we don’t need it)
  • Don’t forget to send your gpg public key to the organizer

What you will have after the party:

  • A list of people you can mail encrypted mail with
  • A list of keys to sign and make a bigger trust ring
  • More information about gpg programs and gpg security

Why we do this:

Is important to increase the amount of encrypted mail to make it more difficult to analize and decrypt. The safety of encryption systems is a balance between the amount of information to decypher and the computing power of the spy… if we have enough encrypted mail they will never reach to decrypt the more importatn ones!

LINUX Course For Beginners

After a long delay and loads of empty promises we finally got ourselves together and prepared a course for all of you who want to unleash the hidden powers of free software. This course is meant for people who have no experience with Linux, who’ve only used Windows (you poor things!) or even have never laid a hand on a computer before. Our focus is to show you how to install, use and do other cool shit with Linux just by click, click, clicking away – no need to give weird commands to your computer or other strange stuff like that. Simple as fuck!

As a basis for the course we have choosen Ubuntu Linux training (you can check it out here) published by the Ubuntu community. As the course manual suggests we will split the course into two days of workshops, eight hours each. Otherwise we’ll go with the flow and be flexible.

The main subjects are:

29.03.2007 Day One

Course starts at 12:00h

– Introducing Ubuntu
– Exploring the Ubuntu Desktop
– Using the Internet
– Installing updates and new applications
– Using OpenOffice Applications
– Customizing the Desktop and Applications

05.04.2008 Day Two

Course starts at 12:00h

– File magement
– Making the Most of Images and Photos
– Playing Music and Videos
– Installing and running M$ Windows applications on Linux

– Ubuntu: Help and Support
– Other issues requested by students

If you want to install Linux on your own machine before the course starts you can do it on Saturdays during SLUG. There you can find people who live to help you with your technical problems. While installing you can use our monitors, keyboards, etcetera, so no need to bring your own! Or you can join the installation party:



Starts at 14:00h

Massive installation party with all the help you could ever need available right there. Afterwards, around 18:00 – 19:00 (depending on how the installation goes) screening of “REVOLUTION OS” -documentary by JTS Moore, as an overwiev on history of Linux, the free software foundation and opensource movement.


Simply send us an e-mail or drop by SLUG. When emailing, please tell us if you want to use your own computer or one of the machines prepared by us. The deadline is 22th of March, but would be nice if you signed up as early as possible. It will give us more time to prepare everything, estimate the number of computers we need and so on.

Everyone is welcome! (Except for pigs, politicians, yuppies and other such scum. Well, they use M$Virus anyway…)

If something is still unclear, you would like to help, give a workshop etc. drop us a line at slug [at] lists [dot] riseup [dot] net
