connections automatically. When direct connections are not possible, data will
be forwarded by intermediate nodes.
By default, nodes authenticate each other using 2048 bit RSA (or 521 bit
ECDSA*) keys. Traffic is encrypted using Blowfish in CBC mode (or AES-256 in
GCM mode*), authenticated using HMAC-SHA1 (or GCM*), and is protected against
replay attacks.
*) When using the ExperimentalProtocol option.
Tinc 1.1 support two protocols. The first is a legacy protocol that provides
backwards compatibility with tinc 1.0 nodes, and which by default uses 2048 bit
RSA keys for authentication, and encrypts traffic using Blowfish in CBC mode
and HMAC-SHA1. The second is a new protocol which uses Curve25519 keys for
authentication, and encrypts traffic using Chacha20-Poly1305, and provides
forward secrecy.

@subsection Configuration of Darwin (MacOS/X) kernels
Tinc on Darwin relies on a tunnel driver for its data acquisition from the kernel.
Tinc supports either the driver from @uref{http://tuntaposx.sourceforge.net/},
OS X version 10.6.8 and later have a built-in tun driver called "utun".
Tinc also supports the driver from @uref{http://tuntaposx.sourceforge.net/},
which supports both tun and tap style devices,
and also the driver from from @uref{http://chrisp.de/en/projects/tunnel.html}.
The former driver is recommended.
The tunnel driver must be loaded before starting tinc with the following command:
@example
kmodload tunnel
@end example
By default, tinc expects the tuntaposx driver to be installed.
To use the utun driver, set add @code{Device = utunX} to @file{tinc.conf},
where X is the desired number for the utun interface.
You can also omit the number, in which case the first free number will be chosen.

@node Invitations
@chapter Invitations
Invitations are an easy way to add new nodes to an existing VPN. Invitations
can be created on an existing node using the @code{tinc invite} command, which
generates a relatively short URL which can be given to someone else, who uses
the @code{tinc join} command to automatically set up tinc so it can connect to
the inviting node. The next sections describe how invitations actually work,
and how to further automate the invitations.
@menu
* How invitations work::
* Invitation file format::
* Writing an invitation-created script::
@end menu
@c ==================================================================
@node How invitations work
@section How invitations work
When an invitation is created on a node (which from now on we will call the
server) using the @code{tinc invite} command, an invitation file is created
that contains all the information necessary for the invitee (which we will call
the client) to create its configuration files. The invitation file is stays on
the server, but a URL is generated that has enough information for the client
to contact the server and to retrieve the invitation file. The whole URL is
around 80 characters long and looks like this:
@example
server.example.org:12345/cW1NhLHS-1WPFlcFio8ztYHvewTTKYZp8BjEKg3vbMtDz7w4
@end example
It is composed of four parts:
@example
hostname : port / keyhash cookie
@end example
The hostname and port tell the client how to reach the tinc daemon on the server.
The part after the slash looks like one blob, but is composed of two parts.
The keyhash is the hash of the public key of the server.
The cookie is a shared secret that identifies the client to the server.
When the client connects to the server in order to join the VPN, the client and
server will exchange temporary public keys. The client verifies that the hash
of the server's public key matches the keyhash from the invitation URL. If
not, it will immediately exit with an error. Otherwise, an ECDH exchange will
happen so the client and server can communicate privately with each other. The
client will then present the cookie to the server. The server uses this to
look up the corresponding invitation file it generated earlier. If it exists,
it will send the invitation file to the client. The client will also create a
permanent public key, and send it to the server. After the exchange is
completed, the connection is broken. The server creates a host config file for
the client containing the client's permanent public key, and the client creates
tinc.conf, host config files and possibly a tinc-up script based on the
information in the invitation file.
It is important that the invitation URL is kept secret until it is used; if
another person gets a copy of the invitation URL before the real client runs
the @code{tinc join} command, then that other person can try to join the VPN.
@c ==================================================================
@node Invitation file format
@section Invitation file format
The contents of an invitation file that is generated by the @code{tinc invite}
command looks like this:
@example
Name = client
Netname = vpn
ConnectTo = server
#-------------------------------------#
Name = server
Ed25519PublicKey = augbnwegoij123587...
Address = server.example.com
@end example
The file is basically a concatenation of several host config blocks. Each host
config block starts with @code{Name = ...}. Lines that look like @code{#---#}
are not important, it just makes it easier for humans to read the file.
The first host config block is always the one representing the invitee. So the
first Name statement determines the name that the invitee will get. From the
first block, the @file{tinc.conf} and @file{hosts/client} files will be
generated; the @code{tinc join} command on the client will automatically
separate statements based on whether they should be in @file{tinc.conf} or in a
host config file. Some statements are special and are treated differently:
@table @asis
@item Netname = <@var{netname}>
This is a hint to the invitee which netname to use for the VPN. It is used if
the invitee did not already specify a netname, and if there is no pre-existing
configuration with the same netname.
@cindex Ifconfig
@item Ifconfig = <@var{address}[/@var{netmask}] | dhcp | dhcp6 | slaac>
This is a hint for generating a @file{tinc-up} script.
If an address is specified, a command will be added to @file{tinc-up} so the VPN interface will be configured to have the given address.
If it is the word "dhcp", a command will be added to start a DHCP client on the VPN interface.
If it is the word dhcpv6, it will be a DHCPv6 client.
If it is "slaac", then it will add commands to enable IPv6 stateless address autoconfiguration.
It is also possible to specify a MAC address, in which case a command will be added to set the MAC address of the VPN interface.
The exact commands added to the @file{tinc-up} script depends on the operating system the client is using.
Multiple Ifconfig statements can be specified, however one should only use one Ifconfig statement per address family.
@cindex Route
@item Route = <@var{address}[/@var{netmask}]> [<@var{gateway}>]
This is a hint for generating a @file{tinc-up} script.
Route statements are similar to Ifconfig statements, but add routes instead of addresses.
These only allow IPv4 and IPv6 routes.
If no gateway address is specified, the route is directed to the VPN interface.
In general, a gateway is only necessary when running tinc in switch mode.
@end table
Subsequent host config blocks are copied verbatim into their respective files
in @file{hosts/}. The invitation file generated by @code{tinc invite} will
normally only contain two blocks; one for the client and one for the server.
@c ==================================================================
@node Writing an invitation-created script
@section Writing an invitation-created script
When an invitation is generated, the "invitation-created" script is called (if
it exists) right after the invitation file is written, but before the URL has
been written to stdout. This allows one to change the invitation file
automatically before the invitation URL is passed to the invitee. Here is an
example shell script that aproximately recreates the default invitation file:
@example
#!/bin/sh
cat >$INVITATION_FILE <<EOF
Name = $NODE
Netname = $NETNAME
ConnectTo = $NAME
#----------------#
EOF
tinc export >>$INVITATION_FILE
@end example
You can add more ConnectTo statements, and change `tinc export` to `tinc
export-all` for example. But you can also use the script to automatically hand
out a Subnet to the invitee. Note that the script doesn't have to be a shell script,
you can use any language, it just has to be executable.

In August 2000, we discovered the existence of a security hole in all versions

tinc as secure as possible. The current version uses the LibreSSL or OpenSSL library and
uses strong authentication with RSA keys.
