Transition to new PGP Key

04 February, 2017 — Platschi

In conjunction with changed circumstances, I am transitioning to a new PGP key. Below you can find a key transition statement signed with the new key. You can also download a copy of the statement here. The new key has been cross-signed with the old key. The old key has been set to expire in two month from today. Please use the new key for any future communication.

Weiterlesen... available via Hidden Service

13 January, 2017 — Platschi

In an attempt to learn more about the Tor Project, I've set up a hidden service for this website of mine. Readers (if any) that surf the web with the Tor Browser are welcome to connect to this page from now on with the *.onion link below.

If you have issues verifying the document below, try it with this file.

Hash: SHA256    4gdkzxy2ompqus2hd2xbqtvyy7ikozwlio673bzqyf3g7rqebxse6aqd.onion (port 80)



How to verify

When on a Linux machine, open the Terminal. Download the file and my PGP Key with:

$ wget
$ wget

You might need to download wget beforehand. Alternatively, you could use curl.

After downloading the files, import my PGP Key to your keyring, then attempt to verify the file:

$ gpg --import platschi.asc
$ gpg --verify hidden.txt.asc

Now, if all went fine, you should either see that I signed the document above with my PGP Key, giving you some little extra confidence that it might have been (probably) indeed me putting that link up there. That is, if you trust my PGP Key for what it's worth.

gpg: Signature made Fri 29 Jun 2018 07:08:25 PM -03
gpg:                using RSA key A7433BD99150AE38408D4547D76D9EB36B20DB71
gpg: Good signature from "Ralf Platschkowski " [unknown]
gpg: WARNING: This key is not certified with a trusted signature!
gpg:          There is no indication that the signature belongs to the owner.
Primary key fingerprint: A743 3BD9 9150 AE38 408D  4547 D76D 9EB3 6B20 DB71

Feel free to contact me if you have questions. More to come in the not-so-far future!

Sichere Kurzmitteilungen auf dem Smartphone: Signal

15 October, 2015 — Platschi

Nachdem ich mit einer kleinen Einführung in den Datenschutz begonnen habe, möchte ich mit einer Empfehlung für Chat bzw. Kurzmitteilungsdienste auf dem Smartphone beginnen.


Einführung in den Datenschutz

11 October, 2015 — Platschi

Über die Jahre hinweg wurden Nerds belächelt, deren Theorien als paranoider Quatsch abgetan. Dieser Quatsch hat sich schlussendlich, spätestens seit Edward Snowden größtenteils für wahr herausgestellt. Kurzum: Geheimdienste und Staaten dieser Welt bauen seit Jahren eine weltweite Massen~~überwachung~~kontrolle auf, von der die Stasi zu Ihren besten Zeiten nicht einmal im Traum dran gedacht hätte.
