I've been tinkering with Python all day today... it's pretty slick. Just for practice, I tried to cobble together a tripcode decoder that would let you have "real" words in your tripcode as !WAHa and Sling and others do, and it actually came out better than I thought it would be. I'm aware there's already a program that does this, but if memory serves me, it's Windows-only and in Japanese besides. My script is kind of dumb in the way it goes about things -- it basically just tears through random strings until it finds one that fits -- but I've tested it repeatedly and it seems to work. If you'd like to check it out, nab it here:

Of course, you may need to modify the hashbang line depending on where Python is on your machine, and don't forget those execute bits, people... Use "-h" for help.
First person to ask how to get this to run on Windows gets pointed and laughed at.
forgive my lack of understanding on this topic, but is it possible to have any tripcode you want, given enough time/resources/whatever?
>>321 here
Sorry, retarded question
What I meant was: I've seen a few trips containing whole 8 letter words, uncanny matches to the poster's name, other things like that. I've used trip.exe and found that the list of trips output for a certain criteria is finite, so my more appropriate question is: is it possible to get EXACTLY the trip you want? if so how?
>>322
It's very unlikely that you could just find an 8 character tripcode that's exactly the one you want it to be, it would possibly take years and years of processing time to find an exact match.
However it might be possible to randomly generate tripcodes and match them against a list of dictionary of 8 letter words, hence you could find full words and then change your name to match the new tripcode. Still wouldn't be very fast though.
>>322
different runs of trip.exe will produce different repeating lists of tripcodes because windows doesn't have random() and it's rand() sucks.
>different runs of trip.exe will produce different repeating lists of tripcode
Interesting, I am running two instances of trip.exe right now, searching for matches to the same string and I'm getting the exact same output from them both.
>>325
If you started them at the same time, that will be the case since the random number generator is seeded by the time in seconds.
Lol, you guys are smart. (Seriously. Not trolling. Some people's knowledge here really impresses me.)
C:\>trip.exe | grep -P \d{10}
`Eqppj9l = 1354773682
eyd!{P0V = 0841327956
I560v;3t = 8550610352
`Eqppj9l = 1354773682

I560v;3t = 8550610352This took ~4hrs to generate. (lol intel celeron)
>>329
What I'm trying to say is that trip.exe PRNG is terribly cyclic: The more complex the search string, the more likely the PRNG will run around in circles.
Instead of using rand(), which does suck horribly, just use this:
s1=((s1&4294967294)<<12)^(((s1<<13)^s1)>>19);
s2=((s2&4294967288)<<4)^(((s2<<2)^s2)>>25);
s3=((s3&4294967280)<<17)^(((s3<<3)^s3)>>11);
return s1^s2^s3;Tausworthe random number generator, generates quality 32-bit random integers with a cycle of something like 2^88, extremely fast and simple. Seeding is left as an excercise to the reader, I just set s1, s2 and s3 to the seed times various large integers.
>>333
Nice. Never could get my head 'round bitwise operators, though...
>>333
Cycle of 2^88? So that is not a linear shift feedback whatchamacallit then?
Oh, of course. There are three variables, so the longest possible cycle isn't 2^32, it's 2^96...
I know it's faster, and the state is much, much smaller, but I'm not sure how it stacks up quality-wise. It's supposed to be a viable competitior, though, and it's certainly good enough for pretty much all casual uses.
>>331,333
here's a better one:
z1=((z1&4294967294)<<18)^(((z1<<6)^z1)>>13);
z2=((z2&4294967288)<<2)^(((z2<<2)^z2)>>27);
z3=((z3&4294967280)<<7)^(((z3<<13)^z3)>>21);
z4=((z4&4294967168)<<13)^(((z4<<3)^z4)>>12);
return z1^z2^z3^z4;Just out of curiosity (I'd like to compare it to the work I'm doing now). How many kilo-crypts per second (kcps) are people getting right now with faster processors out such as a 2.6 ghz core 2 conroe?

I'm managing 520kcps with what I wrote in a couple hours, but that doesn't really say much.
I've been running 3 simultaneous instances of trip.exe for ~40 mins now, and got 31 trips matching a case sensitive 5 character string. Quad core's aiiiite.
More notably though, Vista (which I'm using) gives me completely unique results which is nice.

if you have a fast processor and run it in a decently fast browser like opera or safari it might actually be fast enough to be useful.
on my computers here it's horribly slow in firefox (freebsd and windows xp), slightly better in konqueror (freebsd) and IE 7 (windows xp), and almost fast enough to be useful in opera (freebsd and windows xp) and safari (windows xp). and these machines are all more than 2 years old.

To tie this thing into a current conspiracy theory of mine, since you're all talking about tripcode searchers...
Densha Otoko's trip code was nm4g8qV1Cg.
How long would it have taken, realistically, for someone to crack it in 2004? I'm interested in learning at what point it would no longer be plausible for someone to step forward and claim to be him, citing the tripcode as evidence.

I also get the error message

which affects the line
>>compare=cflag?&strstr:&strcasestr;
The regex version gets similar errors (though with more errors). The package in trippersrc compiles at least but does so with errors.
Any ideas on if I'm missing packages or something?
Specifically (on the trippersrc):
>>gcc -Os -march=pentium -mtune=generic -std=gnu99 -o 2chdict tdict.c || true
returns
>>tdict.c: In function âmainâ:
>>tdict.c:108: warning: implicit declaration of function âfgetlnâ
>>tdict.c:108: warning: assignment makes pointer from integer without a cast
>>/tmp/cco547v3.o: In function `main':
>>tdict.c:(.text+0xc8c): undefined reference to `fgetln'
>>collect2: ld returned 1 exit status
And doesn't compile 2chdict. tripper2ch doesn't seem to work for 4chan and tripperc4 and trippershii don't seem to do anything.
gcc -std=c99 -O2 -funroll-all-loops `pcre-config --cflags` `pcre-config --libs` -lcrypto -o trip trip-regex.cor if you don't have pcre and can't install it:
gcc -std=c99 -O2 -funroll-all-loops -lcrypto -o trip trip.cyou're probably better off using trip-regex.c instead of trip.c if you can. if you have to use trip.c, you should grab it again (i just made some minor changes), and if you still get an error about strcasestr not being defined, try compiling it with -DNO_STRCASESTR.
It needs to use getline instead of fgetln with glibc, because I'm lazy. However, you don't need 2chdit.
>>375
If others are having compile error "optind undeclared" when compiling trip-regex.c, I needed to add
#include <getopt.h>
to the list of includes in trip-regex.c to get it to compile with the command line pasted.

optind should be in unistd.h, not getopt.h.

I assume it's possible to have a tripcode where the input is the same as the output, any examples?
>>403
the input is 8 characters. the output is 10 characters.
so no, it isn't possible.
Not sure where to post it, I don't want to bump really old threads so I'll ask here:
at the initiative of SAoVQ, we are writing a small guide to anonymous boards on a wiki. It's not very good right now, but we've just started: http://tanasinn.info/wiki/A_Guide_to_Anonymous_Boards
On the part about tripcodes, I talked out of my ass about choosing a good tripcode. Could someone who actually understands well the CPU cost of cracking various tripcodes help us to provide an easy rule to follow for choosing something uncrackable?
>>405 tripcodes are designed to be a useful tool in establishing an identity, not a secure one. The length of the #hash is, however, a factor in how long it would take to crack.
>>405
anything shorter than about 6 characters is easy to crack.
anything that's all alphanumeric is easy to crack.
by "easy to crack" i mean it'd take less than a week on my crappy slow computer.
>>406-407
Thanks. But does that mean that realistically all tripcodes are bound to fall in a few weeks of brute-forcing, or that something like #f8&45?p3 is expensive enough to make it way too long for a troll with spare CPUs to crack?
Do you think that "8 characters with letters, numbers, and punctuation marks" is a good enough guideline to provide for a short primmer that is not primarily about this topic?
>>408 That'd likely work; there's not much call for tripcode cracking. That said, make sure you at least make a note that it's not a perfect system, and whatever key they use, don't make it your password for anything else!
A note of caution: Some characters (like &<>"',) get translated into HTML entities, and can push the rest of the characters off the end of the 8-character limit. This is essentially a bug, but is implemented in Wakaba and Kareha for bug-by-bug compatibility with the original implementation.

Hello all,
I stumbled upon this post here (id never even heard of the site here) and i must say this is one of the more interesting reads ive come across.
I was originally looking for a reverse tripcode program. from what ive read here, that seems pretty impossible, and the only thing you seem to have come up with to compensate is a brute force generator.
Most of what was said here kinda flew over my head, but what i DID get has really inspired me to want to learn all about this.
I must confess however, that the reason why i wanted to find a reverse tripcode program may be pretty obvious; i wanted to figure out someones tripcode. But this person is not just some random anon, or an undeniably annoying fellow. This person has some interesting controversy surrounding him/her.
You may or may not have heard about Oversight. If you have, you know where this is going. If you have NOT, please read this:
http://encyclopediadramatica.com/Operation_Falcon_Punch
this person has intrigued me, and i am beginning to think that there is more to his/her riddles than is there for us to see. I have a feeling that his tripcode has something to do with the overall puzzle.
Computer programmers and true "hackers", (not crackers), are by and large, the most intelligent of society because of their strive for knowledge, and the urge to figure out as much as possible.
Because of that, and the prowess you display here, i ask you, if willing, to take a crack at this little mystery.
If nothing else, it will be a chance to stretch those detective muscles i know you all have.
Thank you for this thread, your time, and your knowledge.

P.S. if you want to find me, ask for me in irc.partyvan.fm #fm

You want to crack one of 4chan's secure tripcodes?
Good luck with that, lol.
Why would anyone want to fake being someone with controversy surrounding them?
LOL, go make your own controversy, it's easy enough.
See? That was easy.

Hi again,
I see you guys didnt really like my last post.
Well, can you at least tell me how this Oversight can have a tripcode with two exclamation points at the beginning? i tried putting one before the tripcode, but that didnt work. Really baffled about this one. Shed some light please?
