The easiest way is just to write to me:

address encryption fingerprint public key
h2() PGP
hannes.hauswedell() S/MIME

If you can, please use encryption when writing to me, I can read both PGP and S/MIME, although I prefer PGP. Also S/MIME is used on my work computer which is theoritically a multi-user system.


You can chat with me via XMPP:

But please be aware that I don’t accept presence subscriptions from people I don’t know so you won’t see me as online (you can still write to me and I will answer!).

Please also use encryption when contacting me, but note that I use OMEMO for XMPP and not OTR. My device finger prints will always be published here:
