Rainbow Tables
==============

Precomputed hash-reversal sets for password-audit and research work. These are
very large (tens to hundreds of GB each), so they are not auto-downloaded —
pull the specific set you need from its canonical source below, into this
folder, and it will appear in the browser automatically.

Canonical public sources
-------------------------
  * RainbowCrack project tables (LM, NTLM, MD5, SHA1) — free and paid sets:
        https://project-rainbowcrack.com/table.htm
  * Free Rainbow Tables (community, LM/NTLM/MD5) — distributed by torrent:
        https://freerainbowtables.com/
  * Ophcrack tables (LM/NTLM, incl. the free "small"/"XP free" sets):
        https://ophcrack.sourceforge.io/tables.php

How to add a set
----------------
  1. Download or torrent the .rt / .rtc files into a named subfolder here,
     e.g.  Rainbow Tables/ntlm_mixalpha-numeric#1-8/
  2. Fix permissions so the web server can read them:
        sudo chgrp -R www-data "Rainbow Tables/<set>" && sudo chmod -R g+rX "Rainbow Tables/<set>"
  3. It shows up at https://www.peterbassill.com/media/Rainbow%20Tables

Note on usefulness
------------------
Rainbow tables only help against unsalted hashes. They are mainly of interest
for legacy LM/NTLM audit work and for demonstrating, in awareness sessions, why
salting and modern KDFs matter. For salted/modern hashes a wordlist run beats a
rainbow table.
