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.

hello thar. Why doesn't my tripcodes work? I'm using tripper+ but I don't know how to configure the options because my computer won't show Japanese characters...

afaik, john has bitslice-des code for fruity platforms.
you could take a stab at adapting the 4brute++ code, but i dont even want to think about what parts of it might be endianess-sensitive.
updating the x86 DESBS code to some newer extensions than MMX would be a pretty heroic task for some highly motivated young coder. :)
Hi. Can someone here please explain why my tripcodes doesen't work?
According to a program called tripper+, "#/te¦4M¼A" will generate tripcode: "!aWrYyYlkcw".
But when I tested it on Sandbox, i got "!nbn1dFk5FA"
Why won't it work?
Because it's full of non-ASCII characters that will get parsed differently depending on which board you post it on, especially if you use HTML entities instead of the actual characters. If you want tripcodes that work everywhere, stick to plain ASCII characters only.
>>179
MMX registers are already 64 bits and have NOT AND and such. The only optimization that comes to mind would be vectorizing and doing two at once in SSE2 128bit registers
>>182
i am not so sure you know what bitslicing means. ;)
basicly it means using a CPU with N bit registers as N CPUs with 1 bit registers.
some operations (like DES) can profit from that a lot.
johns DESBS code does 64 "crypt() equivalent operations" in parallel on MMX, or 128 on altivec.
so porting this to newer extensions like SSE(2) would probably get another performance increase by a factor of 1.5-2 ...
but its hard to say without trying it since this stuff is getting really non-intuitive already. (direct influence of ram-speed on the performance, or the retarded linux 2.4.x SMP scheduler eating 70% of the performance, just to name two cute examples.)
>>183
SSE lacks the instructions to do the needed operations on its 128 bit registers, out of all of the additional instruction sets I can think of SSE2 is the only one that fit (I only know x86 chipsets). Maybe I didn't state it cleary, but I said you would not be likely to gain more than just being able to do two times as many as once. Not exactly something that is going to bring something that is currently an unreasonable search to feasability.
Altivec could certainly do it; it's much better than any x86 SIMD. Too bad it's only on the G4 and up. I could manage 32 bits at once, I guess.
>>185
For those curious of the AltiVec performance, a PowerPC G5 1.8 GHz
currently achieves the following:
Benchmarking: Traditional DES [128/128 BS AltiVec]... DONE
Many salts: 1103K c/s real, 1105K c/s virtual
Only one salt: 910566 c/s real, 910566 c/s virtual
The latest Pentium 4's aren't quite there yet (with MMX code).
Although SSE support for JtR is coming, preliminary testing shows that
it won't achieve this much speedup.

>>184
well, it might be enough to shut up those fruituser claims about hardware superiority, considering they are less than factor 2 ahead while using 2x width. ;)
but, seeing how the biggest change in john 1.6.39 is adding a macosx-x86-mmx-cc build target, i guess apple will be shipping real computers before john grows SSE2 support. :)
>>188
Some instructions for using this would be nice.
>>189 doesn't seem to understand much :(
In the G5's case it's entirely CPU bound... I would look into running scalar and AltiVec at the same time, and why jtr's altivec code uses signed numbers.
But since I don't have one, I don't really care. I will see if I can make the non-DES parts parallelizable easily without making it really unreadable. SHA1 is supposedly AltiVecable as well; RC4 doesn't look like it is, though.
RC4 runs like a dream on 8-bit microcontrollers, though.
>>190
to search for a tripcode you just dotrip [regex]
ortrip -c [regex]
where [regex] is the regular expression you want to match. if you don't supply a regular expression it uses .* (matches all tripcodes). if you use -c it does case sensitive matching.
Wow those posts got screwed up..
anyways. Someone asked if it is impossible to crack a tripcode if you use an 8 character random string in aprevious life of this thread. The answer is no, if you really care about being the only one with the tripcode you should use a secure tripcode (name#trip#secure). This is the third and shittiest version of this post I have made. I shall not make another one.
I think the NSA has been attacking this thread to stop this information from getting out!
>>196
Damn bastards cannot leave DES alone! Why bother making the S-boxes resistant to differtial cryptology 15 years before anyone knows about it and then suggest a reduced keysize.. AND THEN hide the information that tripcodes are about as secure as a plastic lock!
does anyone have a copy of 4brute-johnbs?
Not on this board.
Someone really should make a post(somewhere) of all of the technical details of tripcodes. I keep forgetting to verify (and wel.l redo as they are totally fucked up) >>221-222 and list any other inconsitencies. I'm sure I'll eventually get around to it or someone else will do it for me.
Also, is it still 200GET if it isn't the first time?

This is not a tripcode testing thread. Use the testing thread over at /sup/ if you really need to.
A friend has been running tripper2ch on his Macbook looking for "MUSASHI" tripcodes for so long it's reached eight character inputs.
All the hoorj bitslice sse stuff up there is way past my ability to care about this, but maybe I should multithread it or look into OpenMP.

Don't worry. People who take computer science classes feel inadequate in the grand scheme of things too.

I think I'm going to rewrite mine so it uses OpenMP, because OpenMP is pretty cool.
Also I guess it should support modern wakaba and be endian-safe on shiichan. Even though I'm the only one that uses shiichan's.

I am running Tor, but how do I make it (or Privoxy?) aware of .tor domains?
Someone explain the process for generating tripcodes anyway.
I'm goofing around teaching myself php and want to make a tripcode test script for the hell of it.
That'd be re-inventing the wheel. Here's the (slightly poorly-written) snippet of code from Thorn that generates 2ch-style trips:
$pos=strrpos($name,"#");
if ($pos!==false) {
$nombre=substr($name,0,$pos);
$trip=substr($name,$pos+1);
//echo($trip);
//2ch-style tripcodes...
//More or less stolen from Futallaby
$salt=substr($trip."H.",1,2);
$salt=ereg_replace("[^\.-z]",".",$salt);
$salt=strtr($salt,":;<=>?@[\\]^_`","ABCDEFGabcdef");
$trip=substr(crypt($trip,$salt),-10)."";
}
else {
$nombre=$name;
$trip="";
}The point of re-inventing the wheel is that you understand it better and aren't just copying stuff you saw other people do. As it is I can't make heads or tails of your code.
To tell the truth, I have a hard time following it too. Why? Because (as the comments say) it was lifted with few modifications from another (open-source) PHP image board script. And the guy who wrote that probably transcribed it from another image/message board script written in Perl. So I didn't reinvent the wheel either. But you know what? It works.
I'll write it out a bit
$salt=substr($trip."H.",1,2);Take the second and third characters of the trip key with "H." appended to the end of it. This is the "salt."
$salt=ereg_replace("[^\.-z]",".",$salt);Replace characters that don't match the regular expression [^\.-z] (basically, non-ASCII characters) with a period.
$salt=strtr($salt,":;<=>?@[\\]^_`","ABCDEFGabcdef"); Replace a bunch of characters that are ASCII but not letters with letters. Remember that "\\" in this case is an escaped "\".
$trip=substr(crypt($trip,$salt),-10)."";The trip code is the last ten characters of the result of a standard UNIX encryption function, with the trip key and the salt as input. http://us3.php.net/crypt
Wanna rewrite that in your own code? Have fun.
To get it entirely right, you should probably apped "H.." instead of "H.". Also, you should convert from whatever charset you are using to Shift_JIS before doing anything else.
Would conversion to Shift-JIS really make a difference, seeing as it's only working with ASCII characters anyway?
It's not only working with ASCII characters. It's working with the full 8-bit bytes.
For instance, #ﾃδεつεδづつεδεつづδづつεδεつεδづつづδεつづδづつｯﾃδεつεδづつεδεつづδづつづδεつεδづつづδεつづδづつｽﾃδεつεδづつεδεつづδづつづδεつεδづつづδεつづδづつ凝δεつεδづつεδεつづδづつεδεつεδづつづδεつづδづつｯﾃδεつεδづつεδεつづδづつづδεつεδづつづδεつづδづつｽﾃδεつεδづつεδεつづδづつづδεつεδづつづδεつづδづつ�δεつεδづつεδεつづδづつεδεつεδづつづδεつづδづつｯﾃδεつεδづつεδεつづδづつづδεつεδづつづδεつづδづつｽﾃδεつεδづつεδεつづδづつづδεつεδづつづδεつづδづつ催δεつεδづつεδεつづδづつεδεつεδづつづδεつづδづつｯﾃδεつεδづつεδεつづδづつづδεつεδづつづδεつづδづつｽﾃδεつεδづつεδεつづδづつづδεつεδづつづδεつづδづつ� doesn't work if you don't convert to Shift_JIS, and furthermore, tripcodes will change depending on the charset of the board.
...and now, it's not working here. Seems I've got some fresh new bugs to sort out.
Righteous.

Now endian-safe, slightly slower on icc, much faster on gcc.
Switched to FreeBSD crypt() because it's much shorter. Unfortunately also much more bottlenecked in one random-access array lookup that goes to main memory. Didn't switch to the JTR code WAHa sent me because it would ruin my beautifully short program.
Also I forgot to add modern wakaba trips but I'll do it sometime.
This crypt isn't reentrant :(
>>237
freebsd crypt() is faster than openssl crypt on my laptop (turion, 64-bit freebsd), but it's slower on the machine i'm using now (pentium 3, 32-bit freebsd)... i wonder why?

it might have other characters you need to convert...

There's a ~ and / in it, but I don't think those would pertain to HTML entities.

where are you trying to use it? if it doesn't contain any of the characters mentioned in >>268 and you've converted any characters that aren't the same in unicode and shift-jis it should work on wakaba and kareha boards.
futallaby and shiichan (at least the versions used on 4chan) are apparently horribly broken wrt tripcodes.
ok, apparently such tripcodes can be made to work on 4chan.
you just have to set the character encoding to shift-jis before you post.
> futallaby and shiichan (at least the versions used on 4chan) are apparently horribly broken wrt tripcodes.
they're interpreted as utf-8, except on /sjis/ where they aren't. official policy is to not fix this because we hate people who use tripcodes.
