New table format is almost done. :D

Postby Bitweasil » Mon May 23, 2011 1:01 am

It's able to shrink tables to about 40% of their current size, and is much denser (no more null padding in the tables).

:D

I'm working on finishing up full implementation in all the tools - right now, I have some V1 tables hardcoded in places. Once all the tools work with the V2 tables, I'll be making a big release.

Hm... looks like a nice memory leak somewhere in the GRTConvert utility... just ran a box way-bad out of RAM.

I've got NTLM gen support included now, and hopefully get the rest of the stuff finished in the next week or so. And, hopefully, Windows support! :D

32*.4 = 12.8 bytes/chain. Hmm so it seems that you are no longer storing the full hash and converted the start point password to a number?

Pretty much right on!

Password is stored as an offset, hash has a selectable number of bits.

Right now, chains have to be byte length. I'm using 13 bytes for the len8 tables.

Most of the bugs, including the memory leak, are squashed :)

Should have this ready to go soon... working on Windows support now.
