Annotation of src/usr.bin/ssh/COPYING.Ylonen, Revision 1.1

1.1 ! deraadt 1: This file is part of the ssh software, Copyright (c) 1995 Tatu Ylonen, Finland

! 4: COPYING POLICY AND OTHER LEGAL ISSUES
! 5:
! 6: As far as I am concerned, the code I have written for this software
! 7: can be used freely for any purpose. Any derived versions of this
! 8: software must be clearly marked as such, and if the derived work is
! 9: incompatible with the protocol description in the RFC file, it must be
! 10: called by a name other than "ssh" or "Secure Shell".
! 11:
! 12: However, I am not implying to give any licenses to any patents or
! 13: copyrights held by third parties, and the software includes parts that
! 14: are not under my direct control. As far as I know, all included
! 15: source code is used in accordance with the relevant license agreements
! 16: and can be used freely for any purpose (the GNU license being the most
! 17: restrictive); see below for details.
! 18:
! 19: [ IDEA is now *only* included if configured with --with-rsa. ]
! 20: The RSA algorithm and even the concept of public key encryption are
! 21: claimed to patented in the United States. These patents may interfere
! 22: with your right to use this software. It is possible to compile the
! 23: software using the RSAREF2 library by giving --with-rsaref on the
! 24: configure command line. This may or may not make it legal to use this
! 25: software for non-commercial purposes in the United States (I have sent
! 26: a query about this to RSADSI (on July 10, 1995), but have not received
! 27: an answer yet). The RSAREF2 distribution is not included in this
! 28: distribution, but can be obtained from almost any ftp site worldwide
! 29: containing cryptographic materials. Using RSAREF is not recommended
! 30: outside the United States. See "http://www.cs.hut.fi/crypto" if you
! 31: have trouble finding the RSAREF library.
! 32:
! 33: [ IDEA is now *only* included if configured with --with-idea. ]
! 34: The IDEA algorithm is claimed to be patented in the United States and
! 35: several other countries. I have been told by Ascom-Tech (the patent
! 36: holder) that IDEA can be used freely for non-commercial use. A copy
! 37: of their letter is at the end. The software can be compiled without
! 38: IDEA by specifying the --without-idea option on the configure command
! 39: line.
! 40:
! 41: [ All these files are now external to the distribution. ]
! 42: The DES implementation in this distribution is derived from the libdes
! 43: library by Eric Young <eay@mincom.oz.au>. It can be used under the
! 44: Gnu General Public License (libdes-COPYING) or the Artistic License
! 45: (libdes-ARTISTIC), at your option. See libdes-README for more
! 46: information. Eric Young has kindly given permission to distribute the
! 47: derived version under these terms. The file crypt.c is fcrypt.c from
! 48: SSLeay-0.4.3a by Eric Young; he permits free use.
! 49:
! 50: [ GMP is no longer part of the distribution. ]
! 51: The GNU Multiple Precision Library, included in this release and
! 52: linked into the executable, is distributed under the GNU General
! 53: Public License. A copy can be found in gmp-1.3.2/COPYING.
! 54:
! 55: [ Zlib is no longer part of the distribution. ]
! 56: The zlib compression library is copyright Jean-loup Gailly and Mark
! 57: Adler. Anyone is permitted to use the library for any purpose. A
! 58: copy of the license conditions can be found in zlib095/README.
! 59:
! 60: [ This script is no longer part of the distribution. ]
! 61: The make-ssh-known-hosts script was contributed by Tero Kivinen
! 62: <kivinen@niksula.hut.fi> and is distributed under the GNU General
! 63: Public License. A copy can be found in gnu-COPYING-GPL.
! 64:
! 65: Some files, such as memmove.c and random.c, are owned by the Regents
! 66: of the University of California, and can be freely used and
! 67: distributed. License terms are included in the affected files. The
! 68: file scp.c is derived from code owned by the Regents of the University
! 69: of California, and can be used freely.
! 70:
! 71: [ TSS has been removed from the distribution. ]
! 72: The TSS encryption algorithm implementation in tss.c is copyright Timo
! 73: Rinne <tri@iki.fi> and Cirion Oy. It is used with permission, and
! 74: permission has been given for anyone to use it for any purpose as part
! 75: of ssh.
! 76:
! 77: The MD5 implementation in md5.c was taken from PGP and is due to Colin
! 78: Plumb. Comments in the file indicate that it is in the public domain.
! 79:
! 80: The 32-bit CRC implementation in crc32.c is due to Gary S. Brown.
! 81: Comments in the file indicate it may be used for any purpose without
! 82: restrictions.
! 83:
! 84:
! 85: In some countries, particularly France, Russia, Iraq, and Pakistan, it
! 86: may be illegal to use any encryption at all without a special permit,
! 87: and the rumor is that you cannot get a permit for any strong
! 88: encryption.
! 89:
! 90: If you are in the United States, you should be aware that while this
! 91: software was written outside the United States using information
! 92: publicly available everywhere, the United States Government may
! 93: consider it a criminal offence to export this software from the United
! 94: States once it has been imported. I have been told that "the federal
! 95: mandatory sentencing guidelines for this offence are 41 to 51 months
! 96: in federal prison". The rumor is that the government considers
! 97: putting the software available on an ftp site the same as exporting
! 98: it. Contact the Office of Defence Trade Controls if you need more
! 99: information. Also, please write to your congress and senate
! 100: representatives to get these silly and unconstitutional restrictions
! 101: dropped.
! 102:
! 103: Note that any information and cryptographic algorithms used in this
! 104: software are publicly available on the Internet and at any major
! 105: bookstore, scientific library, and patent office worldwide. More
! 106: information can be found e.g. at "http://www.cs.hut.fi/crypto".
! 107:
! 108: The legal status of this program is some combination of all these
! 109: permissions and restrictions. Use only at your own responsibility.
! 110: You will be responsible for any legal consequences yourself; I am not
! 111: making any claims whether possessing or using this is legal or not in
! 112: your country, and I am not taking any responsibility on your behalf.
! 113:
! 114:
! 115: NO WARRANTY
! 116:
! 117: BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
! 118: FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
! 119: OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
! 120: PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
! 121: OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
! 122: MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
! 123: TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
! 124: PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
! 125: REPAIR OR CORRECTION.
! 126:
! 127: IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
! 128: WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
! 129: REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
! 130: INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
! 131: OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
! 132: TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
! 133: YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
! 134: PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
! 135: POSSIBILITY OF SUCH DAMAGES.
