4COPYING POLICY AND OTHER LEGAL ISSUES
5
6As far as I am concerned, the code I have written for this software
7can be used freely for any purpose.  Any derived versions of this
8software must be clearly marked as such, and if the derived work is
9incompatible with the protocol description in the RFC file, it must be
10called by a name other than "ssh" or "Secure Shell".
11
12However, I am not implying to give any licenses to any patents or
13copyrights held by third parties, and the software includes parts that
14are not under my direct control.  As far as I know, all included
15source code is used in accordance with the relevant license agreements
16and can be used freely for any purpose (the GNU license being the most
17restrictive); see below for details.

32restrictions.

34The 32-bit CRC compensation attack detector in deattack.c was
35contributed by CORE SDI S.A. under a BSD-style license. See
