Send me your key, and add my key to your ircd config - usually
<code>~/.config/darkfi/ircd_config.toml</code> where <code>~</code> is the path
to your home directory.
<pre>
[contact."narodnik"]
contact_pubkey = "3YSmJYYVk5B5GtkYpMh62PhbX6DWaHdTqafZtz9q3kdM"
</pre>
Once we exchange keys, we can do encrypted DM using
<pre>
/query narodnik hello
</pre>
Make sure to restart your ircd after modifying the config file fyi.
