      Bread machines are great. I haven't bought a loaf of bread in about three years. If #sonTwo's bread machine has custom settings, I recommend 20 min knead time, changing the rise times (1hr, 1.5hrs, 1.5hrs) and at least 60-70 min bake time. A good recipe is 1 cup water, 2.5 cups all-purpose flour, 2 tbsp […]

      RT @lnxw48a1 #sonTwo texted to tell me that his in-laws bought them a bread machine. Me: Oh, cool! I was thinking the same thing, but it's beyond my current budget. They can sometimes be competitive, but I'm more of *good, you're helping take care of our kids and grandkids*

      I'm near the Great Lakes (about an hour's drive from either Lake Ontario or Lake Huron, depending whether I go South or West). It was 5C for most of the day, about 40F for your USians. Apparently that's normal for this time of year...

      RT @lnxw48a1 About halfway through today's #YoCo ( #yogurt and #coffee ). Indoor temperature is 60°F, outdoor temperature is 30°F. Outdoor cats' water dish has about 0.5in / 1cm of ice on top. Very glad I'm not near the Great Lakes right now.

So they congregate on big #corpocentric #socnets, even when the central corporation running things is actively hostile to their point of view. Then they're butthurt when their accounts are shadowbanned. Years ago, I tried to persuade some local Black […]

      There's also Megablocks, the precursor to Duplo. And there are also Micro Megablocks, the same size as LEGO. The kits for Micro Megablocks were much better than the LEGO kits, making slightly larger models but using only standard bricks. The LEGO models were smaller, depending on many custom pieces specific to the kit, which were […]

Preparing for the Keysigning Cryptoparty, 2 Dec 2013

Posted by Bob Jonkman on November 24th, 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?
