Code signing certificate


As I recently posted about difficulties with code signing certificates, I finally succeeded to finalize the process :see_no_evil: :snail: :sweat: :sweat_smile:!

So the things to I had to do:

  • Go to the Local Register Office for a notary public and pay additional 9€ for the face-to-face authentication form to be validated so two visits to the Local Register Office = 30 km x 2
  • Three evidences: I chose government issued photo ID, Visa debit card and an utility bill addressed to me…

I did get a cool stamp from the Local Register Office though (this is in Finland of course) :grinning:

Next as easy it can be I just scanned the document and three pieces of additional evidence… however this wasn’t enough. The notary public’s identity needed to be verified. I did mention that within EU countries (Great Britain) since something of February 2019 this was no longer required as the Apostille document was now longer needed between the members of the European Union (the document proves that the signing person is an actual person and is at the signing moment in the mentioned profession/duty); Not enough – a verification was required via calling the Local Register Office which was fine by me although I thought they wouldn’t give this information via a privacy concern. Thankfully the notary public’s identity got confirmed! Next I had to explain the meaning of the utility bill because it was written in finnish.

After this I finally got the certificate approved – after few hours spent in the customer support and few emails sent:

Now I can finally provide signed installers! Let’s see how this goes after a year when the certificate needs to be renewed :scream:

The result – note that is my name now in the UAC prompt!


ScriptNotepad released


I’m proud to release the initial version of a software I’m been working (hobby) for about a year called ScriptNotepad.

The software is based on the Scintilla project via the ScintillaNET wrapper library.

The idea is that you can write scripts for text manipulation in C# programming language and run them within the software. There is still a lot to do but I can get no input on feature requests, bugs or otherwise, if the software isn’t available with the public. The software has also spawned many libraries released as NuGet packages and in the GitHub, because I didn’t want to include all the code in a same project.

Do have fun playing with it :sweat_smile: – PS. I have used this on my work place for three weeks now :smirk:
