      Congratulations to Dr. Cooley, and to you! And welcome to Canada!https://twitter.com/SNOLABscience/status/1542562373193633793 I saw the news on Twitter, and said to myself "Hey, I know that person!" It's amazing how familiar we humans feel with each other using only social media...

      I've never played #Minecraft - Is this #Federated software? Is it #FreeSoftware? If so, how can Microsoft control what's happening on someone's private server? Even if such code existed in a #FreeSoftware application, I would have thought there'd be a fork that eliminates that external control. It's time for that now. But if #Minecraft isn't […]

      RT @lnxw48a1 Seen via @sullybiker https://freeradical.zone/@thenewoil/108539077382008407 Microsoft bans in #Minecraft will soon carry over to privately run servers as well. One commenter said "Seems like there is a really simple solution here: Don't be a toxic asshole on a public server." But once $CORPORATION starts interfering with privately hosted servers in any way, those servers' […]

      Mind you, there's something charming and soporific about listening to a professional baseball game with an old-fashioned, laid-back announcer. But most of those have retired... #ASMR

      Applies to all professional #Sportsball: begging to see overpaid drug-users doing something that the rest of us would gladly do for free. When I walked our dog we'd pass the local baseball field, and we'd stop and watch the game for hours. But the one time I went to a professional baseball match (Toronto Blue […]

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.
