+Security statement
+------------------
+
+In august 2000, we discovered the existence of a security hole in all versions
+of tinc up to and including 1.0pre2. This had to do with the way we exchanged
+keys. Since then, we have been working on a new authentication scheme to make
+tinc as secure as possible. The current version uses the OpenSSL library and
+does authentication in much the same way as the SSH protocol does.
+
+Cryptography is a hard thing to get right. We cannot make any guarantees. Time,
+review and feedback are the only things that can prove the security of any
+cryptographic product. If you wish to review tinc or give us feedback, you are
+stronly encouraged to do so.

 Requirements

 Requirements
 ------------
 

-Since 1.0pre3, we use OpenSSL for all cryptographic functions.  So you
-need to install this library first; grab it from
-http://www.openssl.org/.  We recommend version 0.9.5 or better.  If
-this library is not installed on you system, configure will fail.  The
-manual in doc/tinc.texi contains more detailed information on how to
-install this library.

 Features
 --------
 

-This version of tinc supports multiple virtual networks at once. To
-use this feature, you may supply a netname via the -n or --net
-options. The standard locations for the config files will then be
-/etc/tinc/<net>/. Because of this feature, tinc will send packets
-directly to their destinations, instead of to the uplink. If this
-behaviour is undesirable (for instance because of firewalls or
-other restrictions), please use an older version of tinc (I would
-recommend tinc-0.2.19).
-
-In this version, MAC addresses are stripped off before encoding and
-sending a packet. When the packet reaches its destination, the MAC
-addresses are rebuilt again. They then have the form
-FE:FD:aa:bb:cc:dd. aa, bb, cc and dd are taken from the destination
-and source IP address.  See the manual for more detailed information.
-
-tincd regenerates its encryption key pairs. It does this on the first
-activity after the keys have expired. This period is adjustable in the
-configuration file, and the default time is 3600 seconds (one
-hour). If you send a USR2 signal to the daemon, it'll regenerate
-immediately.

+In order to force the kernel to accept received packets, the destination MAC
+address will be set to FE:FD:00:00:00:00 upon reception. The MAC address of the
+ethertap or tun/tap interface must also be set to this address. See the manual

+This version supports multiple subnets at once. They are also sorted on subnet
+mask size. This means that it is possible to have overlapping subnets on the
+VPN, as long as their subnet mask sizes differ.

-Things left to do to make cabal superstable:
---------------------------------------------
- * Check for connection loops. Inter-daemon
-   connections should always satisfy the
-   tree property.
- * Redundancy: multiple ConnectTo lines, if
-   one fails others might be tried.
- * Allow connects to hosts that use
-   nodirectdata.
+Todo list (in no specific order):
+
+* Compression
+* Routing by MAC (allows for more than only IPv4)
+* Store private key in a separate file
+* Sanity checks on configuration directory
+* Use efficient tree algorithms instead of linked lists
+* Reenable queues for delayed packets
+* Broadcast/multicast
+* Windowing, chaffing, scattering, background noise
+* ABC protocol (superscalabilty)
+* Proxy ARP
+* Eazy setup scripts (graphical?)
+* FreeBSD and Solaris ports
+* Threading
+* Everything else not mentioned.
