Why not?

Although Cisco contributes to a few open source projects, as far as I know the Cisco routers os (IOS)is not freeware and not open source. By giving the source away you most likely commit a crime and I think you may be in troubles... The only exception I am aware of is the that after purchasing Linksys, Cisco had to give away the sources of the WRT54g Os has it used some open source components, but cisco was quite quick to close the loophole.

yeah u are right by saying that after purchasing it or may be by taking the membership...

I think the file you got is invalid or incomplete.even this might be extracted(sometimes it gives error if file is incomplete).or try winrar[^]

There is n "source code for wpa2". Actually there are many. It is an algorithm, thus can be implemented in several (almost all) programming languages, so there is no "one and only" source code if it. And it is highly hardware dependent.
The algorithm is summarized here: http://en.wikipedia.org/wiki/IEEE_802.11i-2004[^], but you can read the whole standard here: http://www.elektormedia.com/EthernetToolbox/Data/Standard/802.11i-2004.pdf[^]

But most of the implementations will be in C, here is an open source router firmware repository: http://www.dd-wrt.com/wiki/index.php/Compiling_DD-WRT_Sources[^], the soure is at svn://svn.dd-wrt.com/DD-WRT/src/squashfs-tools, but you need an SVN client to browse it.

Btw: the tar file is the oldest of all archives. You can use 7Zip for example to open it.
