I had a client that needed passwords recovered that they had stored within an application called Xshell. Xshell is an SSH client for Windows. So after I had done this I went about creating a small command line utility for just this purpose.
This has been tested on Xshell v5, after a quick look, it appears that version 6 is now available and I have no idea if this will work on the newer version. Regardless here is the app for download.
