Does this create the .onion addresses? Sounds fun. What algorithms are used to create the .onion address?

if it is like vanitygen, then it creates thousands of address a second and sees if it made an address that matches a filter the user made. so if i ran vanity gen for 3 days for an address with 1ctoon6, it would generate till it found one that started with 1ctoon6

If this is like that, then it would be pretty good to have address that made real words.

On a GPU that would be a very difficulty address to generate. And if you paid someone to generate it for you, they would have the private key to it...

Thats true but thats why i would just do it my self and find one similar that was outputed.... i'll just keep generating new addresses until i find a good one Tongue

I'll offer a 10 btc bounty for what the OP described, for a modification to the shallot program to take advantage of a gpu. Payable upfront to a trustworthy member of this forum.

yea it's exactly like vanitygen except it generates .onion addresses

iirc vanitygen is also cpu only based? it would be nice to see both of these ported to gpu based  Smiley

I was under the impression that vanitygen already generated addresses using gpu's opposed to cpu's, and it still take forever to find a long name. If that's not the case, then how hard would it be for vanitygen to be gpu based?

Perhaps I've misunderstood this post, I am interested in being able to generate vanity .onion domain hashes using a gpu - hence the modification to the shallot program.

ive been looking for the same thing

shallot is awesome but its cpu only

so it takes like a month + to generate 8 characters of vanity

any longer than 8 is basically impossible (well implausible time wise)

again this is for generating vanity .onion addresses for the tor network not for bitcoin addresses

likely with a program named shallot and a really fast cpu and some patience

a vanity onion with 8 specific characters like silkroad take approximately 25 days to hash on a 1.5 ghz cpu

Time to Generate a .onion with a Given Number of Initial Characters on a 1.5Ghz Processor

|=======================================
|characters | time to generate (approx.)
|         1 |         less than 1 second
|         2 |         less than 1 second
|         3 |         less than 1 second
|         4 |                  2 seconds
|         5 |                   1 minute
|         6 |                 30 minutes
|         7 |                      1 day
|         8 |                    25 days
|         9 |                  2.5 years
|        10 |                   40 years
|        11 |                  640 years
|        12 |                10 millenia
|        13 |               160 millenia
|        14 |          2.6 million years

I was able to hash an 8 character onion the other day with a AMD 3.6 Black Edition Quad Core in Under 48 hours - I have a feeling luck had a little bit to do with it though

and as far as a bounty I would donate 5 BTC to this

thanks

@OP is the point of this so you can get the priv key to existing onion addresses?

If you're not excited by the idea of being an early adopter 'now', then you should come back in three or four years and either tell us "Told you it'd never work!" or join what should, by then, be a much more stable and easier-to-use system. - GA

I'd like to announce Scallion, my OpenCL vanity .onion address generator. It gets around 600MH/s on a 6870, allowing it to generate an 8-character prefix in just 15 minutes on average. It's written in C# and runs in both Linux (on Mono) and Windows.

Features:
1) Blindingly fast - 600MH/s vs. 2MH/s for shallot
2) Performs PKCS #1 v2.1 sanity checks via openssl's RSA_check_key function
3) FOSS - MIT licence
4) Support for 1024, 2048, or 4096 bit keys
5) Estimates time required to generate a key (on average)

Check out the Github page: http://www.github.com/lachesis/scallion
or skip straight to the binaries: https://github.com/downloads/lachesis/scallion/scallion-v0.9.zip

If you have any problems, reply to this thread or open an issue on github.

Awesome! Now if only I still had a server to run a hidden service on.
