The licences which components of this software falls under are as

follows. First, we will summarize and say that 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

[Tatu continues]
|
|
* 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, ie.
|
|
|
|
- RSA is no longer included, found in the OpenSSL library
|
|
- IDEA is no longer included, it's use is depricated
|
|
- 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
|
