The data format used by the zlib library is described by RFCs (Request for

Comments) 1950 to 1952 in the files http://www.ietf.org/rfc/rfc1950.txt

(zlib format), rfc1951.txt (deflate format) and rfc1952.txt (gzip format).

This file is part of the OpenSSH software.

The licences which components of this software fall under are as follows. First,

we will summarize and say that all components are under a BSD licence, or a

licence more free than that.

OpenSSH contains no GPL code.

As far as I am concerned, the code I have written for this software

can be used freely for any purpose. Any derived versions of this

software must be clearly marked as such, and if the derived work is

incompatible with the protocol description in the RFC file, it must be

called by a name other than "ssh" or "Secure Shell".

However, I am not implying to give any licenses to any patents or

copyrights held by third parties, and the software includes parts that

are not under my direct control. As far as I know, all included

source code is used in accordance with the relevant license agreements

and can be used freely for any purpose (the GNU license being the most

restrictive); see below for details.

[However, none of that term is relevant at this point in time. All of

these restrictively licenced software components which he talks about

have been removed from OpenSSH, i.e.,

- RSA is no longer included, found in the OpenSSL library

- IDEA is no longer included, its use is deprecated

- DES is now external, in the OpenSSL library

- GMP is no longer used, and instead we call BN code from OpenSSL

- Zlib is now external, in a library

- The make-ssh-known-hosts script is no longer included

- TSS has been removed

- MD5 is now external, in the OpenSSL library

- RC4 support has been replaced with ARC4 support from OpenSSL

- Blowfish is now external, in the OpenSSL library
