network spoofing tools

[iinfi]

i am trying some encryption software and tools like encrypting emails using pgp's desktop encryption and encrypting files for transferring over network etc.

i want to test whether it is really encrypted while it moves over the network. do we have any tools which spoof the local network so as to get plain text and/or encrypted data traveling through the network?

Sun VirtualBox + WireShark

Install a new OS in VirtualBox, link it with the host OS (pretty simple) and use WireShark to sniff the packets through the adaptor
