Pretty Good Privacy (OpenPGP)
In case you use GnuPG for example, there is a public OpenPGP key associated with the label’s email address so that you can send me encrypted mails or mails with encrypted files attached. The key is available for download and should be imported to GnuPG in order to make it accessible:
$ gpg --import zerocat.pubkey.asc
Note that this webpage could have been manipulated, so please check the downloaded key’s fingerprint with the one that you have received via email, business card or flyer, as soon as possible. If the fingerprints don't match, something weird is going on.
$ gpg --fingerprint zerocat

Key fingerprint = D39A EE2E 477C 0492 55F4 E329 9BFA 2CB7 7D3D 1A27
uid [unknown] Zerocat (True Free-Design Hardware Tools) <zerocat@posteo.de>
sub rsa4096/0x0A816BC8478C6C07 2017-11-21 [E] [expires: 2025-03-31]
Improved Security without SHA1
This key should come without obsolete SHA1 Signatures, and the list of
algorithm preferences has been changed such that weak SHA1 Encryption
will hopefully be avoided. In case you are updating your old existent
zerocat key, we recommend to remove the old key first with $ gpg
--delete-key zerocat
before importing the new one.
Copy & Paste
Alternatively, you may gather the key by copy&paste and store it under a filename of your choice. Please apply the rules mentioned above as well.
$ cat zerocat.pubkey.asc
