If you’re interested in encrypting your whole life, or at least parts of it, I suggest you read up on PGP and Gnu Privacy Guard (GnuPG). The internet is full of bad and mediocre tutorials but there are also a few good ones by the Electronic Frontier Foundation (EFF) and by a future boy.

My public key

Below is the public encryption key for Marcel Stör, (my first name at this domain) in armored OpenPGP format. This lets you write encrypted emails that only I can read!

Don’t worry: you don’t have to read this. You can copy-paste it or download it in a plaintext file. If you want to import it from a keyserver it’s publicly hosted at openpgp.org: https://keys.openpgp.org/search?q=marcel@THIS-DOMAIN-HERE-DOT-COM.
