1 This file is part of the OpenSSH software.
3 The licences which components of this software fall under are as
4 follows. First, we will summarize and say that all components
5 are under a BSD licence, or a licence more free than that.
7 OpenSSH contains no GPL code.
10 * Copyright (c) 1995 Tatu Ylonen <ylo@cs.hut.fi>, Espoo, Finland
13 * As far as I am concerned, the code I have written for this software
14 * can be used freely for any purpose. Any derived versions of this
15 * software must be clearly marked as such, and if the derived work is
16 * incompatible with the protocol description in the RFC file, it must be
17 * called by a name other than "ssh" or "Secure Shell".
20 * However, I am not implying to give any licenses to any patents or
21 * copyrights held by third parties, and the software includes parts that
22 * are not under my direct control. As far as I know, all included
23 * source code is used in accordance with the relevant license agreements
24 * and can be used freely for any purpose (the GNU license being the most
25 * restrictive); see below for details.
27 [However, none of that term is relevant at this point in time. All of
28 these restrictively licenced software components which he talks about
29 have been removed from OpenSSH, i.e.,
31 - RSA is no longer included, found in the OpenSSL library
32 - IDEA is no longer included, its use is deprecated
33 - DES is now external, in the OpenSSL library
34 - GMP is no longer used, and instead we call BN code from OpenSSL
35 - Zlib is now external, in a library
36 - The make-ssh-known-hosts script is no longer included
37 - TSS has been removed
38 - MD5 is now external, in the OpenSSL library
39 - RC4 support has been replaced with ARC4 support from OpenSSL
40 - Blowfish is now external, in the OpenSSL library
42 [The licence continues]
44 Note that any information and cryptographic algorithms used in this
45 software are publicly available on the Internet and at any major
46 bookstore, scientific library, and patent office worldwide. More

49 The legal status of this program is some combination of all these
50 permissions and restrictions. Use only at your own responsibility.
51 You will be responsible for any legal consequences yourself; I am not
52 making any claims whether possessing or using this is legal or not in
53 your country, and I am not taking any responsibility on your behalf.
58 BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
59 FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
60 OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
61 PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
62 OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
63 MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
64 TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
65 PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
68 IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
69 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
70 REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
71 INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
72 OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
73 TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
74 YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
75 PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
76 POSSIBILITY OF SUCH DAMAGES.
