Preparing for the Keysigning Cryptoparty, 2 Dec 2013

Posted by Bob Jonkman on 24th November 2013

Key Pair

Cryptoparty like it’s 31 December 1983!

At the next KWLUG meeting on Monday, 2 December 2013 I’ll be demonstrating how to do e-mail encryption with Thunderbird and Enigmail. If you’ve never used e-mail encryption before then bring a laptop, and we’ll create keys and learn how to use them. We’ll save the lesson with pointy sticks for another day.

For those people who already have GnuPG/PGP keys I’m also hosting a Formal Keysigning. Participants will introduce themselves, read their GnuPG key fingerprint, then anyone else is invited to vouch for that person:

Bob: “I’m Bob Jonkman, and my GnuPG fingerprint is 04F7 742B 8F54 C40A E115 26C2 B912 89B0 D2CC E5EA”

Andrew: “I’ve known Bob since the early days, and that’s really him”

This is a great way to expand your Web Of Trust to include people whose keys you might not otherwise sign (because you don’t know them very well, or they only have ID issued by an authority you don’t like). With all these introductions and vouchings the chance of someone misrepresenting their identity is vanishingly small, so you can trust that the key fingerprint they read is really associated with that person.

To make this process go smoothly I’d like to have a printout of all the participants’ keyIDs, UserIDs, and key fingerprints, which I’ll distribute at the keysigning. That way you can just check off each name/keyID/fingerprint as people read them, and then sign their keys later at your leisure. But to get that printout I’ll need the public key of anyone who would like to participate in the keysigning.

If you’re using Thunderbird and Enigmail then open the Key Management window, right-click on your key and select “Send Public Keys by E-mail”, and send it to me ( bjonkman@sobac.com )

If you’re a command-line weenie then use

gpg --export 0xYOURKEYID > 0xYOURKEYID-public-key-for-YOURNAME.pgp

and send that file 0xYOURKEYID-public-key-for-YOURNAME.pgp to me (substitute your actual keyID and actual name as needed).

Of course, I’d prefer signed, encrypted e-mail, but public keys are public (so encryption isn’t necessary), and public keys should already be self-signed anyway.

Unfortunately, if you’re creating your keys for the first time at the meeting you won’t be able to send me anything now. You can still participate in the vouching process, and we’ll have an informal keysigning after the formal keysigning, where all you need to do is read your fingerprint straight from your computer and those people who already know you can sign your key.

I’m still working on the procedures for the formal keysigning; you can see the work in progress (and contribute!) on the Formal Keysigning page on the Wiki.

Thanx, and hope to see you on Monday, 2 December 2013!

–Bob, who is the Keymaster. Who will be the Gatekeeper?

Cryptography and Security Events in Kitchener-Waterloo

Posted by Bob Jonkman on 9th October 2013

The months of October and November are shaping up to have some great lectures and presentations on cryptography, security and privacy.

Sheet of paper, strips of paper

Keysigning materials

Yesterday started off with an informal keysigning at the KWLUG meeting. The presentation was on the Scratch programming environment, nothing to do with GnuPG/PGP or cryptography. But a few of us exchanged little slips of paper with our key fingerprints, verified that the name with the fingerprint matched the person we knew, signed the keys, and so improved our standing in the Web of Trust. I hope that this becomes a regular part of all KWLUG meetings. The more people that participate, the more confident we can be about the validity of keys we may not have verified ourselves.

Today I attended the first UofW CSClub lecture on Security and Privacy by Sarah Harvey. If you’ve been following the news about the Snowden revelations you’ll know why security and privacy is important. The room was full of computer science, math and cryptography students, so the discussions were deep and technical.

There was a vacancy in the November KWLUG meeting so I asked Sarah if she would repeat her lecture. Let’s see what the KWLUG bosses have to say

There are more CSClub lectures scheduled, check the schedule on the CSClub site.

I’ve volunteered to do a presentation on Encrypting E-mail with GnuPG, Thunderbird and Enigmail, followed by a formal keysigning. I’m developing the presentation notes and keysigning procedure on the KWCrypto Interest Group Wiki that was set up after the Kwartzlab keysigning party last year. Please join me on the Wiki and the mailing list — I’d appreciate the help.

–Bob.

System Administrator Appreciation Day Dinner

Posted by Bob Jonkman on 10th July 2012

Pictures are up!

300 new servers? By next Tuesday? Sure, no problem!

System Administrators install servers

System Administrator Appreciation Day falls on 27 July this year, a global celebration of System Administrators around the world. To see what System Administrators do, have a look at some of the systems they have to administer.

After the KWLUG meeting in July, Becky asked me where System Administrator Appreciation Day is being held. “It’s a global event”, I said, but Becky was hoping for something a bit more local. So we decided to have a System Administrator Appreciation Day Dinner. What better way for System Administrators to celebrate than by treating ourselves to dinner?

If you can read this, thank a System Administrator

System Administrators maintain web sites

So, if you’re a System Administrator, married to one, or good friends come join us!

Friday, 27 July 2012 from 6:00pm to 9:00pm iCal
Egg Roll King Restaurant (map)
85 Courtland Avenue East 
Kitchener ON

Your computer ate all your files? I can fix that!

System Administrators make backups

If you’re planning on coming, let me know by e-mail or in the comments by Wednesday 25 July so that I can reserve enough seats and egg rolls for everyone.

–Bob & Becky

More GNU/Linux Resources

People have asked me about GNU/Linux resources in K-W, so here are some of them, gathered in one convenient place. This is by no means an exhaustive list (yet). If you know of others, please let me know in the comments.

KW Linux Users Group — http://kwlug.org
The KWLUG mailing list for general discussion is where all the action is, along with a “Help” list for specific questions. Microblogging as @kwlug and !kwlug on Identi.ca and also @kwlug on Twitter.
Ubuntu Canada KW chapter — https://wiki.ubuntu.com/CanadianTeam/KitchenerWaterloo
There’s a low traffic Ubuntu-CA-KW mailing list. Microblogging on Twitter as @ubuntuwaterloo and on Identi.ca as @ubuntuwaterloo too, with a group at !ubuntucakw. Some members can also be found on the IRC channel #ubuntu-ca-kw on Freenode.net.

Ubuntu-CA-KW has regular Ubuntu Hours in Kitchener (first Friday of the month) and Waterloo (third Wednesday of the month) announced on Identi.ca, Twitter, and sometimes the mailing list.

Ubuntu Canada — https://wiki.ubuntu.com/CanadianTeam
Again, the Ubuntu Canada mailing list is where the action is, but there is also a web forum and the Ubuntu-ca.org website. Check out the Ubuntu Canada events listing. There’s an !ubuntuca group on Identi.ca, and many people can be found on the IRC channel #ubuntu-ca on Freenode.net.

Feedback from Copyright Consultation submission

Posted by Bob Jonkman on 24th September 2009


A few days after I posted my Canadian Copyright Consultation submission I received some e-mail feedback from Robert:

Hello Bob Jonkman,

I’ve read most of your input about U.B.B. and found it surprising that you, a software developer of all people, would oppose the U.B.B. ruling.

I’ve read your blog: [link]

While reading, I’ve stumbled upon this:

“I favour shorter copyright terms, no criminalisation for
non-commercial infringement, no criminalisation of circumvention of technical protection measures, and no media levies.”

Now, as a software developer, someone who uses copyright and programs protections, to what extent that you favour the above sentence?

My reply:

Hi Robert: As a software developer I am especially concerned with Usage Based Billing. I need to access online documentation, I use forums, blogs, and mailing lists to interact with other developers and clients, I run servers both for production and to test Web applications. But what will affect me most is downloading programs, software tools, and complete CD and DVD images with operating system distributions. All this activity puts me well beyond Bell’s proposed limit of 60 GBytes per month. Connection fees will nearly double for me under UBB, and I get nothing for it.

The statement on copyright, that I favour shorter terms and no technical protection measures are completely consistent with my position as a developer. In the first place, I need to use materials that are either freely available, or purchased from commercial sources. Bad licenses that use copyright law to restrict my use of material that I’ve legally purchased are harmful to me. For example, I want to write an addressbook program for a smart phone. But the vendor has restricted my ability to read the phone’s memory, and claims it is infringing that vendor’s copyright for me to reverse engineer the phone. This is harmful to me (I can’t do the work), it is harmful to my client (who can’t get the software he needs), and it is actually harmful to the phone vendor (because neither I or my client will ever buy that phone again).

Reduced copyright and fewer technical protection measures are also good for me, because more people will be able to make use of my software, leading to more work for me. Note that I never use “programs protections” for my software — it’s just not good for business. And while my software is copyrighted, I still grant licenses under GPL to make copies, requiring only that those who use my code give me attribution, and that their code uses the same license.

I don’t sell software, by the way. People pay me to write software. The software that gets written either belongs to the client (“work for hire”, so the client has the copyright), or I retain copyright and release the code under GPL.

Some of the submissions are now posted online. Alarmingly, many of the submissions I read online are not on the site. Hopefully the immense backlog has merely delayed the Copyright Consultation folks, and they’ll appear soon.

[Added 8 October 2009: It seems my copyright submission was posted on the Copyright Consultations web site on 2 October 2009]

Even if you didn’t make a submission, you can still write to your MP and the Honourable Minister of Canadian Heritage, James Moore and the Honourable Minister of Industry, Tony Clement to let them know your views.

You can contact me too. Post a comment, or send me e-mail.

–Bob.
