COPYING POLICY AND OTHER LEGAL ISSUES
As far as I am concerned, the code I have written for this software
can be used freely for any purpose. Any derived versions of this
software must be clearly marked as such, and if the derived work is
incompatible with the protocol description in the RFC file, it must be
called by a name other than "ssh" or "Secure Shell".
However, I am not implying to give any licenses to any patents or
copyrights held by third parties, and the software includes parts that
are not under my direct control. As far as I know, all included
source code is used in accordance with the relevant license agreements
and can be used freely for any purpose (the GNU license being the most
restrictive); see below for details.
[ RSA is no longer included. ]
[ IDEA is no longer included. ]
[ DES is now external. ]
[ GMP is now external. No more GNU licence. ]
[ Zlib is now external. ]
[ The make-ssh-known-hosts script is no longer included. ]
[ TSS has been removed. ]

The 32-bit CRC implementation in crc32.c is due to Gary S. Brown.
Comments in the file indicate it may be used for any purpose without
The 32-bit CRC compensation attack detector in deattack.c was
contributed by CORE SDI S.A. under a BSD-style license. See
