First, we will summarize and say that all components 5are under a BSD licence, or a licence more free than that. 6 7OpenSSH contains no GPL code. 8 91) 10 * Copyright (c) 1995 Tatu Ylonen <ylo@cs.hut.fi>, Espoo, Finland 11 * All rights reserved 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 42 [The licence continues] 43 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.
