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
Ben Lindstrom033e4552001-09-18 05:36:27 +000029 have been removed from OpenSSH, i.e.,
Damien Miller7294baa2000-09-30 14:40:39 +110030

Kevin Stevesd85bf4b2001-02-11 16:43:05 +000032 - IDEA is no longer included, its use is deprecated
Damien Miller7294baa2000-09-30 14:40:39 +110033 - 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
