Customizing OpenSSH

Question

I currently am assigned to investigate and somehow find a way to "customize" (make modifications re authentication, constants, messages, etc) OpenSSH and being the "web-based" guy that I am, I really don't know where to start. So comments are highly appreciated.

Questions:

1. I downloaded the latest snapshot from here, I believe this is the code I am supposed to "customize" right?
2. For confirmation: Can I "customize" these codes in Windows?
3. Is OpenSSH a "library" that I need to call externally from codes I'll be writing or the "program" itself that I need to edit?

Sorry for the noobish questions but I just need expert comments on this. Thanks.

Answer 1

First off all which kind of customization you wants ,please be clear.

1.I downloaded the latest snapshot from here, I believe this is the code I am supposed to "customize" right?

So latest code is here http://openbsd.org.ar/pub/OpenBSD/OpenSSH/portable/openssh-6.4p1.tar.gz

2.For confirmation: Can I "customize" these codes in Windows?

You can but compilation is easy in linux so please modify and compile your code in any linux machine, refer this link for compiling and configuring openSSH http://www.linuxfromscratch.org/blfs/view/svn/postlfs/openssh.html

3.Is OpenSSH a "library" that I need to call externally from codes I'll be writing or the "program" itself that I need to edit?

OpenSSH is not a library its a ssh server and client programs which runs on linux.
