**Make sure you PGP verify this file.**

You can contact me through my personal email:


If you want to contact me securely, you can use my PGP, however, as you know, PGP does not support forward secrecy, meaning if someone manages to steal my/your private key, they would be able to decrypt all of our conversation. If you prefer, mail me so I can create a disposable key so we can communicate somewhat securely. Make sure you read this before sending me an email.

My current PGP key is the following:

$ gpg -K

I have owned (and still do) the following keys:

However, 0xF2403AC05942EE08 has been revoked and 0x18C46052168892F7 will soon be revoked too.


Alternatively, we can use XMPP with TOR + OTR. Mail me for my OTR fingerprint. Here are some of my jabber ids:

(<_at> should be replaced by @ and the same for <dot> to .)

benmezger (_at) riseup (dot) net
benmezger (_at) jabber (dot) de
me (_at) benmezger (dot) nl
benmezger (_at) autistici (dot) org

Other means of communication

I also use Cryptocat. My username is seds.

For the worst case scenarios, you can contact me through Telegram, but don’t. Mail me if you would like my number, so we can talk through Signal.
