-This version of tinc relies on the GNU Multi-Precision Library
-(gmp). This library is available from your nearest GNU mirror. Please
-install this first even before trying to run configure. If you don't
-do this, configure will (hopefully) mention it to you.

+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
+------------
+
+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.
