5are under a BSD licence, or a licence more free than that.

12     *
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".
18
19    [Tatu continues]
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.
26
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.,
30
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
41

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
47    information can be found e.g. at "http://www.cs.hut.fi/crypto".

50    permissions and restrictions.  Use only at your own responsibility.
51    You will be responsible for any legal consequences yourself; I am not

53    your country, and I am not taking any responsibility on your behalf.

67
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
