I generate a set of alpha-numeric 1-8 mysqlsha1 table with winrtgen.
How can i make a perfect version ?
Is there a way to convert tables that produced by winrtgen to perfect version?

I can't be sure without doing the math, but I'm pretty sure that's infeasible with one PC.
Plus, making perfect tables requires the generation of 10 times as much data. Or is it 100?
I can't recall.

Yes, but all the files has to be in the same table index (eg _0_), which is NOT the default in winrtgen. You should also know that perfecting a rainbowtable makes the success % drop, and you have to generate a lot more chains to correct for that.

Alone Bump. Any chance on bribing you to share PowerBlade? I'm too lazy to code it up myself lol.

rtperfect can be made to do 14 times less 64 bit compares for tables with 220 files and 1.5 times less 64 bit compares for tables with 10. If you implement a min heap instead of a linear search.

Hi everyone,
I got a question, if you use rtperfect to make perfect tables and you need to generate more tables too get a higher succes rate, how do you know the succes rate after perfecting the tables? and how do you know if you have enough 'normal ' tables?
If you have 'normal' tables with a succes rate of 99,99%, how do you know what the % is after perfecting them?
thnx
Christiaan

Christiaan Well I just posted this http://www.freerainbowtables.com/phpBB3/viewtopic.php?f=2&t=264 or you could look for a RT calculator. Side note I just noticed that I got "patches welcome"

I used the rtperfect tool, but if I want to use the perfect tables I get the error, in cain or rcrack, rainbow chain lenght verify failed, I tried sorting the perfect tables but it doesn't seem to help.
BTW: sc00bz thnx for your excel sheet i will take a look at it

The tables you perfect, do they all have the same index number? (eg _0_ or _1_) They MUST have the same index number
