Tripcode decoder?

Name: Anonymous 2007-12-03 19:48

is there anyway to convert a tripcode into the password for that tripcode, im using tripsage and I see that you can put in a word you want to see in a trip code and it produces results of passwords that would produce a tripcode with those letters in it, so if we were to take a complete tripcode someone has and enter it into that field, in theory it should eventually produce the 1 password that produces that tripcode, however i have a core 2 duo e6600 which can run 170,000 crypts per second but with over 10^80 possible combinations(numbers + letters + capital letters + symbols, and 10 characters in a tripcode) it would take litteraly much more than trillions of years to run through every combination. Any other suggestions?

Tripcodes are one-way only. It's not computationally feasible to reverse a tripcode to it's original form (it's in NP)

What? They are one-way only. I'm not entirely sure what the point of your post is, perhaps we can discuss it further in this thread.

I think he's trying to criticise you for putting a hyphen in "one-way"

Which is a pretty nitpicky thing to sage about.

Ah, two very possible situations, but which one is reality? Perhaps we'll never know...

I hope you don't think that is the reason hashing functions are irreversible.

Hey, i've got some 16-digit MD5 hashes I'd like you to expand back into their original 9-GB DVD images! Can you do that for me?

by the way, a tripcode can be made out of the entire ASCII set

soooo it's actually 10^256

Or it would be, if there weren't only 95 printable characters in ASCII. And if that were true, which it isn't.

Not to mention that it would be 256^10, not 10^256.

actually i think this one is slower:

here are two things that use it:

Hi there,
I was messing around with JTR a few days ago and wrote this here new tripcode bruteforcer called 4d (short for 4DES_john_brute). Inspired by 4brute, it uses John the Ripper's (bitslicing) DES facilities, and supports both an incremental search and a wordlist mode. It's written in C and should be fairly portable (as JTR, 32bit - 64bit... multiple architectures...). Testing shows performance is ~5 times that of fully-optimized OpenSSL-based crypts (on x86 Win32).

Note: it only supports keylengths>3 characters, and avoids redundant features. For less than that, use 4brute; it shouldn't take over ~5 seconds.

Links to sources + Win32 binaries:
http://www.stashbox.org/64821/4d-v0.1.7z (4d v0.1 + JTR v1.7.0.2)
http://www.stashbox.org/64818/4brute-mod.7z (4brute-mod (w/fixes + WinNT support))
http://www.stashbox.org/64817/dotrip-mod.7z (dotrip-mod (shows trip and crypt))
(Included binaries are native Win32 .exes (gcc -O2 and minor optimizations). Also included are sample scripts (build, prepare-wordlist...), and a partial, test wordlist.)

Important: see README_4d.txt for usage, tips, how to build for your system, and dev-notes.

And please feel free to improve and add to it (see TODOs).

BTW - 4brute was released 2004/12/22, exactly 3 years ago. :P

http://stashbox.org/65705/4brute-mod.7z (4brute-mod (w/fixes + WinNT support))

Messed with it a little bit more, did TODOs and modified the DES_bs_cmp_* functions for a ~20% speed-up. Now ~all CPUtime is spent in the crypt_all function... Still, the more prominent option here is the wordlist mode...

Again, see README_4d.txt.

http://stashbox.org/67097/4d-v0.3.7z (4d v0.3 (Also included is an SSE build))

Cleaning, error handling, latest JTR CVS (IA64 arch.), PGO builds, and works on multiple tripcodes at once (from a passfile and/or repeated -t switches). Overall a ~1% speed-up over 0.2 (>99% CPU is only DES now).

Oh wow. Tripcode Explorer is much faster (5.4MTrips/sec) than the crap I was using before (my own searcher with some shitty C# crypt)

I know there's a patched English version of Tripcode Explorer, but where? I can't read moon runes.

Just guess. The checkbox underneath the search textbox seems to be case-sensitivity (tick for insensitive). Start, pause and stop buttons are obvious. Go to Tools, Options (you can tell from the letter in brackets), make sure to tick the SSE2 option. Choose appropriate amount of threads.
