Alice opened the door and found that it led into a small passage, not much larger than a rat-hole: she knelt down and looked along the passage into the loveliest garden you ever saw. How she longed to get out of that dark hall, and wander about among those beds of bright flowers and those cool fountains, but she could not even get her head through the doorway.

Wsh, "Web Shell" - remote UNIX/WIN shell, that works via HTTP/HTTPS. The package contains two perl scripts for server and client hosts, one C source code and one Java servlet code for the server host : the client script is for console usage and the server scripts run as CGI/Servlet scripts on the target host.

The client part provides shell-like prompt, encapsulating user commands into HTTP POST requests and sending them to the server part script on the target web server directly or via HTTP proxy server. The server part extracts and executes commands from HTTP post requests and returns STDOUT and STDERR output as HTTP response messages. By default both scripts encode HTTP data with Xor.

The key Web Shell features: SSL support (*), Command line history support (*), File upload/download, Protect server part script usage with secret key inside HTTP message, Data flow Xor encoding, Can work trough HTTP proxy server.

(*) - Additional packages are required on the client host.
