If you want to create a custom GPU rainbow table set, just post the charSet & length and we will help you figure out the *best* numbers for it.

Request example :
numeric#1-13, success probability = 99.9 % ( miss 1 in 1000 )
or
mixalpha-symbol32#1-7, total RT set < x GiB, 99% < success probability < 99.9 %

1epi -

I'm debating adding a page to the site with such "play with the numbers" things. Anyone know a good Javascript guy who could whip something like this up in JS such that you could play with the sliders and it would show you the results?

anyone have plans for len8 tables, they seem useful i'll be interested to see the configs, i'm assuming they would be in the hundreds of GBs.
We'll probably make them as a group or something if anyone is up for it.

let's not forget this little picture.
dark blue - tables generated by FRT
light blue - tables covered by the tables generated

eh lightblue = ones covered?

i didn't know GRT had one covering lower-alph-num-1-8 and loweralpha 1-9. or did some1 privately generate?

euc = 10668277737 ~= 10670000000 //expected unique chains - these are the perfect chains in your rainbow tables, this is what you get in the end.

http://www.wolframalpha.com/input/?i=45890588208+%2F+%286.60318588168+%2F+2+%2B+1%29

using the formula
perfectTableSuccessRate ~= 1 - (1 - expectedUniqueChains / keySpace) ^ chainLen
perfectTableSuccessRate = 0.78461
perfectTableSetSuccessRate = 1-(1-0.78461)^3 = 0.9900074 ( ~99% )

I don't know the actual compression rate of your rainbow table format
so I can't give you exact numbers on table set size.

Why 3 tables ?
Because it's more space efficient this way, see here why.
