Tripcode decoder (696)

1 Name: Albright!LC/IWhc3yc 2004-11-15 08:25 ID:UYlEBzaw [Del]

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:
http://www.anre.org/crap/detripper.bz2

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.

By that measure, it'll take this guy 2 * 36 weeks, or a year and a half. 8-character codes just aren't going to turn up, unless you're incredibly lucky like m0hey/p0ri. Even then, his tripcode was kind of in l33tspeak and not exactly what he expected.

it took me about half an hour to find this tripcode... of course that was when i was having a run of unbelievably good luck.
after i found this one i left the tripcode searcher running for about 6 hours and found !HOTaRuCUtE, too.

I found this one completely by accident when playing around with a trip searcher. Took me less than 2 hours.
Too bad it doesn't seem to work on 4chan at all; it's perfect for /prog/...

The trip came way before the whole identity of Mohey, so i wouldn't exactly say there was much planning to get a unique trip from the get-go.

Would it be conceivable to brute force every possible combination and result, and then save that as a list for future reference? Or would searching such a list take longer than brute forcing each combination again?

511 Name: Anonymous : 2008-12-27 13:17 ID:Heaven [Del]

>>510
searching the list could be pretty fast, if you store it in a format that's fairly well optimized for searching. the biggest problem i've found with this approach is that the list would take up several teraby tes of space, which i don't have.

512 Name: Anonymous : 2008-12-27 14:21 ID:GJ/xN8rO [Del]

>>511
Then perhaps a list with a dictionary of common words in different combinations, rather than every possible combination, perhaps?

> the biggest problem i've found with this approach is that the list would take up several teraby tes of space,

Far more than that.

You have a 56-bit keyspace, which is 65536 teras or 64 petas, and each one of those is not a byte, but several. In addition, you would have to keep the auxillary data to mangage it.

A binary search over 64 petarecords takes only 56 divisions, so searching the table would be many orders of magnitude faster than bruteforcing.

But anyone with that amount of storage would not be using it to store tripcode tables anyway.

In theory, a google search would find every tripcode listed on that site.

Also remember the keyspace is more than 56 bits. The second and third byte of the key affect the salt used if you use characters outside the range 0-127, and since the algorithm changes various other characters with htmlspecialchars and by character set translation, there are other effects of using characters with the high bit set.

>>514
Hooooooooooooly shit! Those pages have got to be dynamically generated.

Also, those tables don't even allow upper+lowercase+digits in the same tripcode, or at least from what I've seen.

> Also remember the keyspace is more than 56 bits.

actually it's less than that. you can't use control characters, and the & character can only be followed by certain sequences of characters.

>>517
Erm, no, sorry... it's more.

If you use sjis characters in positions 2 and 3, it alters the salt value used without changing the 56-bit key. Same goes for using characters with the high bit set in other positions, and control characters as well as &"#<> etc. are still usable by setting the high bit - so long as it's still valid Shift-JIS data.

Determining the actual keyspace is fairly difficult, since sjis is a stateful encoding and what byte values are allowed is dependent on previous input data, but it's definitely more than 56 bits.

Naively storing the tripcode list is indeed far too space-consuming. There exist more efficient methods however, most notably rainbow tables. You can build them with RainbowCrack and a tripcode hash patch, courtesy of /prog/ (original code is slightly mangled by Shiichan and forgot &amp;)

520 Name: Anonymous : 2009-01-11 09:41 ID:Heaven [Del]

I wonder if the person who posted that patch was basing the implementation on >>312-314, which is also missing &amp;.

In related news, various threads suggest that 2ch doesn't seem to run htmlspecialchars -- or at least, not for some characters.
Namely, lots of the "novelty" tripcodes listed in posts like http://gimpo.2ch.net/test/read.cgi/puzzle/1129465527/203 have such characters as & and ' in them. It doesn't make a ton of sense to me for someone to post these if they have to be reencoded in order to be used, considering the "fixed" tripcode could be posted just as easily and it's a fairly trivial process. So what gives?

Hi. Believe it or not, this is the OP. (I hope I got my tripcode right - it's been a while.)

Even though the links in my posts have been 404s for years, I'm still getting an absurd amount of traffic from them. Could a mod please do me the favor of removing those links just to stop flooding my server's logs with requests to those files? Much thanks if you can.

it took me FUCKING 100 MINUTES to figure out where to click in that poorly designed WEB 2.0 bullshit to download the file.
and then i had to reload the page 5 times to get a captcha that wasn't black text on a dark blue (almost black) background.

also, your file has a lot of duplicates in it.

I'm a professional web developer now. No, really. I've done a lot of stuff with the Drupal CMS in the last two years or so and I'm really enjoying it. And I've improvedc to the point where I'd rather just forget about that thing I released a while back. No, not the tripcode decoder; the other thing. If you don't know what I'm talking about, just forget it. I hope nobody's still using it.

>>556

Okay, perhaps I'll try emailing him.

>>560

Because I suspect it's not humans who are hitting the links. There just can't be that many people who are interested in five-year-old tripcode decoders written by a Python n00b. (I haven't really used Python since, BTW.)

most people wouldn't admit to switching from python to php, let alone call it an improvement.
