know when they are online. Let's solve this problem once-and-for-all
in a decentralised, sustainable and future proof way.
-## Here come's the real IPv6 friend
+## Here comes the real IPv6 friend
Instead of using a single system or server, we use IPv6 to connect to
our friends directly. Because each of our friends is reachable by IPv6
It's a bit geeky, but it works actually rather simple.
To become a real IPv6 friend, you need to do the following things:
-- Generate a GPG key with a comment named RIF following the URL of
- your computer
+- Generate a GPG key with a comment named **RIF** following the URL of
+ your computer (f.i. **RIF https://nico.ungleich.cloud**)
- Ensure that the URL points to the IPv6 address of your computer
- Setup a webserver on your computer
- Export your key and all real IPv6 friend keys to your webserver as
- For each of your friends, check whether they are online
- Import the friends of your friends and check whether they are
online, too!
+- Send friend requests (like other platforms!)
### Example: Generating a key with the right comment
curl -6 -s https://nico.ungleich.cloud/rifkeys | gpg --import
```
-You can also use
+You can also use the included rif-importfriends.sh.
+
+
+### Example: Updating your friends
+
+Now that you have imported the friends of your friends, they have
+automatically also become your friends!
+
+Obviously, you will want to check whether you even want to sign some
+of the friends (keys) that you downloaded, but clearly you want to
+show off with the biggest amount of friends (that's what is most
+important anyway, isn't it?).
+
+In any case, to update your friend list, simply repeat the command you
+ran above already in the beginning:
+
+```
+gpg -a --export RIF > /var/www/html/rifkeys
+```
+
+Or use the included `rif-exportfriends.sh`
+
+### Example: Importing friends of all friends and exporting them
+
+From time to time you might want to checkup on which friends gained
+new friends and add them to your friend list. This is as easy as
+iterating over all your friends and importing their friends into your
+friends list. And because you are a good friend, you might want to
+export all friends again.
+
+To make things easy, the included a script `rif-friendimportexport.sh`
+automates this process.
+
### Example: Sending a message to a friend
-Simply use your mail program for that.
-And obviously enable signing & encrypting the email.
+You can probably just use your mail program for that - and you might
+even be able to send it IPv6 only!
+
+### Example: Invite a friend
+
+Live is not great without friends! Let's invite a friend! This is as
+easy is this:
+
+```
+printf 'Hello yournamehere!\n I am looking for real IPv6 friends.\n You find my friends on https://nico.ungleich.cloud/rifkeys.\nHow real IPv6 friends find each other is explained on https://code.ungleich.ch/nico/rif.\n Looking forward to befriend you!' | mail -s "friend request" ipv6@your.friend.example.com
+```
+
+And obviously this is waaaaaaaaay to long to type. That's why
+`rif-invitefriends.sh` puts this nicely into a script.
+
+Attention: this requires a working mail setup on your computer
+(i.e. outgoing emails sending by `mail` works).
+
+## Finding friends
+
+As real IPv6 friends are decentralised, there is no central registry
+of friends. Just startup the webserver on your machine, export your
+key(s) and ping your friend.
+With every friend that is added to your network, the reach grows in
+the chain of all friends of every friend!
-## To be added
+So just start in your small cycle and forward your friend URL to your
+friends!

+## About
-- **rif prepare**: check webserver, keyring, etc.
-- **rif online**: check who is online
