Free Rainbow Tables Looking For New Admin

lee writes "After almost three years online, the admin of Free Rainbow Tables has decided to call it a day, citing a lack of time to keep it running. (I'm sure that you all know a rainbow table is essentially a giant list of precomputed hashes.) This is a shame, as the site is a useful resource for those occasions when you really need an existing password exposed, rather than simply changing it. I'm a Windows admin, and this site has come in very handy in the past. The currently computed tables weigh in at well over half a terabyte, are available as torrents from the site, or from a couple of mirrors (and alternatives are available). When the site was active, it featured a downloadable BOINC client to put your idle cycles to work computing ever-greater tables, and a space-saving format for storing the tables. The admin is willing to hand over source code if you wish to take over, though I suspect hosting is not included!"

Salts?

[Sir_Lewk]

I thought the prevelance of using salts with hashes obsoleted rainbow tables years ago.

Once you've reverted the hash back to salt+plaintext, it's *much* easier to remove the salt (often some string concatenated with the plaintext).

True. Correctly salting your password hashes will make rainbow tables useless.

But ... Guess which system still doesn't salt passwords? Windows!

Only MD5/LM/NTLM?

I was expecting more tables than just MD5 and two types of Windows passwords. You can already download the Ophcrack DVD to do Windows passwords with rainbow tables.

Renderlab offer wifi WPA rainbow tables: http://www.renderlab.net/projects/WPA-tables/ . I hope whoever takes over takes note of projects like that, and tries to expand the range of tables available.
