    • New note by bobjonkman 14 January 2023
      I seem to recall there's a standard API that should be common to all the #StatusNet derivitave servers. I'm pretty sure that in its infancy Mastodon conformed to that API. But Mastodon's API expanded beyond that, and I suspect some of the common API was removed, probably around the time #OStatus was dropped from Mastodon […]

      Twidere has stopped working for Twitter accounts. My Mastodon account still works nicely. I thought maybe the Twidere API keys for the developer had been revoked, or that something had gone wrong with my phone (It's a vanilla Samsung with Android 12, but I've refused to install any of the Samsung or Google apps). I […]

      RT @heluecht !Friendica Admins As you might have heard, there are issues with the Twitter API. Several favourite clients stopped working, while others (still) do. By now there hadn't been any word if there is some massive Problem or if this was some deliberate action. Whatever is causing these issues, at least my connection still […]

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.
