Enigmail and the YubiKey


If you can’t sign/decrypt with a YubiKey and Thunderbird/Enigmail you might want to add --pinentry-mode=ask to the “additional parameters for GnuPG” in the Enigmail configuration

The Story

After setting up all the cool Encryption stuff using a YubiKey I was so happy that everything worked.

And then I set up using the YubiKey for SSH as well as described in the documents I linked in the last blogpost. It took a reboot for everything to work out as I wanted it, but I was happy. Until I wanted to send a signed Email using Thunderbird/Enigmail.

YubiKey for 2FA and GPG

A few years ago Marco Pivetta and I chatted about YubiKeys. He described his setup which was absolutely amazing to me at the time. The most intriguing point was, that he could get the 2-Factor Authentication tokens from whatever phone as long as he had the YubiKey with him.

Recently my phone broke and I had to setup the whole 2-factor authentication thingy again and again. That was the time I remembered that chat again. So I decided to test it out.

The future of

Since my last post about my personal feelings about the shutdown note for a lot has changed! The feelings I expressed are still valid but are backwards directed. Sometimes it is necessary to express thise feelings to then be able to look forward and see where to go next. So in this case.

Joe Ferguson took the lead and managed to herd a great bunch of people to keep going. And I’m honoured to be one of them. So let’s see what the future brings and especially how we can avoid such frustration for others in the future. I know we already messed up on at least one occasion but nobody’s perfect….

An open letter to the Maintainers

This is my personal reaction to this github-issue

To be honest: I’m disappointed. And frustrated.

Lornas note about closing down got me rather by surprise. As a long time contributor the project and maintainer of a I knew that we were loosing traction. That was one of the reasons why I tried to get us together to find a way out of this stale situation. Sadly we never managed to find a date or time. And due to the stale situation and no real or timely response to PRs and Issues peoples attention drifted away from the project. So the base of people that contributed intensely faded. But there were still some people left. Not only me but f.e. Scott or Dan.

I would have expected a call from the maintainers to those few people that were still contributing and showing that they cared about the project about the situation and to find a way out. Have a discussion with them. It might have been that we all agreed on giving up. But we will never find out as it didn’t happen.

Instead we are confronted with a fact. Presented by someone that stepped down as maintainer some time ago.

That is frustrating. Especially as we tried to gain traction by assigning tickets an easy-pick label just a few days ago. To attract new contributors. Reading that there were no people willing to step up as maintainer is frustrating when you multiple times offer to help out. When you offer to take action in different fields, all you need are the keys: and nothing happens.

And it’s disappointing: I thought we’d communicate differently. Disappointing as the offer was provided multiple times to help out to keep the project running (The offer was never taken). Disappointed that the information did not come from the maintainers but from someone not really actively involved anymore.

Sorry to say so and I still want to be alive. But I’m increasingly thinking about just letting it go. It was an interesting time and taught me a lot. Perhaps it also teaches me how to let go and how to handle frustration and disappointment?

Convert a Website to SVG

It might not be a common task to convert a Website to SVG but in my case I wanted to have a screenshot that I could scale like a website but that was independent from reloading stuff from the internet. Background is that I wanted to embed a tweet in one of my slides for a talk.

So far I did that with a screenshot but that is not scaleable so depending on the projector it wold show up either very small or as pixel-art. Most of the things in such an embedded tweet are text and should be scaleable to almost any size, I thought. So why not get a vector-graphic instead of a pixel-graphic from that embedded tweet?

And after asking for help on twitter I found (thanks Stephan) HiQPdf that can convert pasted HTML into SVG.

Create the SVG

So I copied the complete website from the embed-preview on twitter into the HiQPdf-Form and got an SVG-file that looked the same as the webview from Twitter. So it works.

Though when I wanted to include that SVG like the screenshot I took previously, I realized that something was not quite as good. The width was not correctly set, so I had do do some manual work afterwards as well.

And it turned out that from the 100kb I got as an SVG-file I could remove almost 84kb as they where empty statements that did nothing at all. And the width and height-values that were given in the SVG-tag where also not completely correct. So after removing the bloat and setting the width to a better value (by trial and error) I even got a file smaller than the sceenshot I took previously. 16kb for the SVG compared to about 24k for the PNG.

And then the SVG behaved exactly like the PNG except for the better scalability!

So all in all using SVG instead of PNG for screenshots can work out great with a tool like HiQPdf (there for sure a re multiple others, I just didn’t test them) but be prepared to at least set the width and height correctly and if you want to have smaller files also expect some manual work to debloat the SVG.

And here are the results:
