Greetings to people at the forums!

I wish that ntlm_loweralpha-numeric#1-9 could be generated on freerainbowtables.com

log_2(36^1+36^2+36^3+36^4+36^5+36^6+36^7+36^8+36^9)=46.56
too big. must be <43
36=26+10
26 : a-z
10 : 0-9
1-9 password length

Say what? xD

you need to keep that number under 43, because frt can't create tables that large, it would take months to make them, only after we have CUDA rainbow table generator implemented we can attack 2^46.56 and more...
36^1+36^2+36^3+36^4+36^5+36^6+36^7+36^8+36^9 = 104461669716084 = 2^46.56 is the number of password combinations for loweralpha-numeric 1-9. (loweralpha=a-z : 26, numeric=0-9 : 10)
like : a,b,c...z,0,1,...9,00,01,02,...,09,...,99,0a,..zz,aaa,..........zzzzzzzzz - "there are" 104461669716084 "passwords" like this in loweralpha-numeric 1-9.

That's a real shame.

I hope this table is eventually made though.

EDIT: Why is that?

as i said, because of the current cpu power, and table size.(don't really know how big the tables would be, if you want i'll calculate it...tomorrow)

where do you get the 2^43 limit from haxor? please calculate the currently generated mixalpha-numeric 1-8

Sc00bz wrote that limit somewhere ...
so it's feasible even 2^48

2^43 was not a limit it was roughly the largest key space we had done so far. Well there is always the chance I fu-bared my wording and made it seem like it was a limit. The limit is something higher than 2^51.38 and that's being limited by 20 mbps bandwidth and it will take 66 days for 99.9%. Only problem is it's 2TB so not many people will be able to download it if the server had enough bandwidth to upload it. For some reason no one knows (99% of people) how to set up their router to forward ports to their computer or sets maximum upload to near zero. So torrents don't work to well.

Code: Select all

I just ran into this post from a year ago.

Wow my grammar is really bad. "Just letting you know, most tables from FRT have key spaces around 2^43.0 or less." I swear I always proof read... most of the time. Ahh I get it, I drop, change, or add words when I'm reading to make the sentences correct like the first time I read, "wow is my grammar is really bad."

This topic never really finished...

So can we do the table I requested? ntlm_loweralpha-numeric#1-9?

Yes and it will take about half the time it took to create ntlm_mixalpha-numeric#1-8.
loweralpha-numeric#1-9 has a key space of 2^46.57
ntlm_mixalpha-numeric#1-8 has a key space of 2^47.66

Now that I know we can do this, when WILL we do this?

ntlm_loweralpha-numeric#1-9
