Following are my various public keys for encryption, signing and authentication.
OpenPGP Fingerprint #
Modern email client software, like Thunderbird, will retrieve the public key automatically using my email address. To verify, that you are using the right key, you can compare it with the fingerprint displayed below:
5143 E0D3 C00C 9DB4 55BD
FD76 7223 89E4 2736 2DC5
The safest way would be to get it from me in a personal meeting.
SSH Public Key #
In case you need to give me access to any of your computer systems trough SSH. I’m using an authentication subkey of my OpenPGP key stored on a security token, as SSH key to autheticate myself against a server.
You can use GnuPG to retrieve the public key using my OpenPGP fingerprint to you keyring:
gpg --locate-keys 0x722389E427362DC5
Once you have my public key in your keyring you can export it in the required format for use with an SSH server:
gpg --export-ssh-key 0x722389E427362DC5 \
S/MIME Certificate #
As a fallback, in case your are not able to use OpenPGP.
I have a personal x509 certificate, issued by WISeID. WiseID did a very basic online authentication check.
The certificate can be used to encrypt mails by S/MIME or for authentication against web services.
To use it, one has to download it manually and import it in the software to use it.
The SHA-265 fingerprint of this certificate is:
7573 856F 132F 2AFF 6FDF 3580 DFC3 D42C
B03A 7237 84C9 9482 4770 F518 B9C7 2DFE
