/prog/ - Tripcode Rainbow Table

Name: Anonymous 2010-02-21 18:11

How did this guy generate his data?

http://trip-table.com/

He would need to know the salt being used in the tripcode generation right?

And wtf is wrong with him putting them in a non-queryable format? Straight html over multiple pages? Come on guy, you would save bandwidth if you just had a database back end to query.

Anyway, even though he says not to use a downloader, I wrote a python script to automatically download and insert them into a sqlite database (Fuck his bandwidth, he should have put them in a database anyway), but after a while I figured it was going to take too long and gave up because I don't really give a shit.

Holy shit, who would want to look through that mess for a tripcode?

Isn't the salt well known?

These aren't secure codes, the salt is known. Also, this table is far from complete.

Oh it is? I didn't know... did someone brute force it? Or did someone steal it or what?

He didn't store it as a database because he's a stupid nip.
No really, those guys are terrible programmers.

It's always been open. That's kind of the point - to allow people to identify themselves across sites.
You're thinking of secure tripcodes, which have a different salt from website to website.

Oh... so why aren't tripfags constantly being impersonated by trolls?

It does happen, it just takes tons of time to crack a tripcode.

Are you sure you understand how this works?

Because the tripfags are the trolls

I can't imaging most tripfags are choosing inputs that are anything other than a 5-8 character dictionary word.

On the contrary, they run programs known as "tripcode crackers" that generate billions of tripcodes trying to find ones that say things like "dick," "faggot," "linux," and "waifus." How the hell do you think they get obnoxious names like Lolicon into their trips, a lucky guess?

The kind of "tripfag" that just puts a dictionary word as their tripcode usually isn't a huge problem anyway.

Exactly
Take this one for example: 2 capital letters, 4 lower case, a number and a symbol.
You only need to type it in once, and have Firefox (or browser of choice) remember it for you

Generate? Why would they waste time generating static data instead of downloading them in a database? That's fucking retarded. And out most tripfags I see, only like 1 in 25 has a novelty trip.

I've run SQL queries against databases with a million records before, and it comes back nearly instantly. I can't image a database with only tripcode-input and trip-code output would be too unreasonable to query, even if it had 100 million records. And having it run on a B Squad box so it doesn't even use your main CPU cycles would make it even easier.

Because tripfags want an identity and so they would use one not in the database, or go secure. The trips still need to be generated at least once for the database.

It seems a waste of speed to be generating the same shit over and over again on the fly.

A complete rainbow table would take several Petabytes of disk space (without compression), and a rather large amount of CPU time to calculate.

Name: Anonymous 2010-02-21 18:57

>>18
It is, but lets face it, it isn't feasible or useful to generate every trip and so if people want identities, then they are going to go for one that isn't known.

What is a complete rainbow table? How many characters max in the input?

Is there such a thing as a "close enough" rainbow table, that only uses a limited size input?

Most people don't want to store a huge-ass-fuck database of millions of tripcodes on their hard disk. Actually, when I say "millions" I'm being conservative at best - tripcode generators running on intel i7 processors generate and search literally millions of tripcodes per second, and even then they have to run the crackers for hours to get a good one. Maybe that will give you some kind of idea of how much space a comprehensive database of tripcodes would take up.

Take into consideration the fact that we have to perform regex searches on these trillions of tripcodes and you can hopefully see that even with a database, the performance increase doesn't really outweigh the cost of storing such a massive database.

Oh, and please stop replying to this topic, it's stupid.

I think that's what the link in OP has, except it's not a table it's a shitty website that nobody wants to navigate and CTRL-F on every page to find something cool.

Hours for something like "find the phrase 'ilikedicks' case-insensitive." For the exact phrase "ILikeDicks" case-sensitive, replace hours with days or weeks.

>>25

Who gives a fuck, stop posting. In any case, using petabytes of storage to archive tripcodes is a gross misappropriation of resources.

Alphanumeric is 62 characters, the output for 8 char inputs would be 62⁸x10 ~= 2 PB.

In this post, we’ll share how to make one of these storage pods, and you’re welcome to use this design. Our hope is that by sharing, others can benefit and, ultimately, refine this concept and send improvements back to us. Evolving and lowering costs is critical to our continuing success at Backblaze.

IIRC, tripcodes on japanese sites tend to use an algorithm that outputs an 8-character tripcode, while western sites use a variation that outputs a 10-character tripcode. Don't quote me one that, though.
