-- This script uses the unpwdb and brute libraries to perform password
|
|
-- guessing. Any successful guesses are stored in the nmap registry, under
|
|
-- the nmap.registry.credentials.http key for other scripts to use.

|
|
-- x The Driver class contains the driver implementation used by the brute
|
|
-- library
|
|
--
|
|
-- @args http-brute.path points to the path protected by authentication
|
|
-- @args http-brute.hostname sets the host header in case of virtual hosting
|
|
-- @args http-brute.method sets the HTTP method to use (default <code>GET</code>)
