Wat??

Sending a message to a webmaster with his public key… The idea behind this I actually got from an April fools released by c’t magazine. To cut a long story short they claimed that weak GDPR phrasing could be a reason that common letter post might need to be properly encrypted. They even provided a tool that extracts a websites public key use it to encrypt a provided message.

You can find the article (in German) here and the tool here

Anyway. I was thinking how I could use this to send webmasters encrypted messages when they do not offer public keys emailing. And for some reason I do not was to ask them for keys. Maybe because I am incredibly clever and shy at the same time … never mind.

Some basics

To get a basic understanding how symmetric and asymmetric encryption – to say the relationship between public and private keys – works just watch this video. I started adding captions in English. Hopefully they will be released into the wild soon.

Preamble (just skip it or click and read it, whatever)

A quick way to get yourself your LAN – well not ad-free but way ad-less.
This blog post will be some weird mix between this existing post here, updates for it and less verbiage.

Just a side note: Browser-based ad blocking is way more efficient rather than filtering using DNS filter lists. The reason for this is that those in-browsing scripts can adjust the appearance of a website directly while DNS based blocking simply does not allow content from specific domains to be loaded. Depending on the used browser the result may vary.
So why wasting time and money to set something up like this? Three reasons:

I decided to continue this in English as you may have noticed. Simply to get more reach.

Preamble

As some of you might already have guessed I am doing electrical stuff in my employment, including electrical engineering. For this purpose our company utilised Eplan Electrical P8. Other examples for such an engineering software would be Elcad, AutoCAD Electrical or WSCAD and some more. Just Google for it if you want further information.

 

Licensing

Eplan using USB dongles to protect their software from piracy. The dongle has to be connected to your computer in order to start the software and keep it running. Removing the dongle causing the software to stop working until you either reconnect the dongle or close it.
If you want to use Eplan on another PC you have to hand over your dongle. This is quite impractical especially if your company has multiple workstations in different places but does not want to invest in more of these quite expensive Eplan licenses.

The solution for this issue is buying a so called network license. You still will receive a dongle which has to be connected to any PC which later will serve as license server. Eplan utilizing DCOM services to achieve this.

Preamble

From time to time I crawl through multiple websites around the world searching for a good-to-go every day carry pick kit. Unfortunately I could not find one that perfectly fits my needs.
No doubt there are lots of nice kits out there like the Peterson Eagles Nest, the Sparrows Tuxedo or even the Dangerfield Praxis pick. However all of them have disadvantages for my taste. For the examples shown the Peterson handles are very thick and bulky, so they would take up LOTS of room in the pick case. The Sparrows Tuxedo does not contain a pry bar and the Praxis Kit case is way too big.
