+On September the 15th of 2003, Peter Gutmann contacted us and showed us a
+writeup describing various security issues in several VPN daemons. He showed
+that tinc lacks perfect forward security, the connection authentication could
+be done more properly, that the sequence number we use as an IV is not the best
+practice and that the default length of the HMAC for packets is too short in

 prove the security of any cryptographic product. If you wish to review
