# This script will look up a collection of MD5 hashes (from a file) against the following databases
|
|
# via md5cracker.org:
|
|
# authsecu, i337.net, md5.my-addr.com, md5.net, md5crack, md5cracker.org, md5decryption.com,
|
|
# md5online.net, md5pass, netmd5crack, tmto.
|
|
# This msf tool script was originally ported from:
|
|
# https://github.com/hasherezade/metasploit_modules/blob/master/md5_lookup.rb
|
|
#
|
|
# To-do:
|
|
# Maybe as a msf plugin one day and grab hashes directly from the workspace.

# Authors:
