Vanitygen: Vanity bitcoin address generator/miner [v0.22]

[nimda]

Is there a way to specify for it to generate a short address, perhaps as short as 27 characters? The limit for the length is anywhere from 27 to 34. 34 by far the most common.

What flavor of RegEx does vanitygen use? It doesn't seem to support PCRE-style anchors.

Ok, what would be the string to type in to return a ltc vanity? Is there one?

use -X with the apropriate verison (given in hex)

So just use L in hex?

example in linux

Code:

./vanitygen -X 48 LTC

Just make sure pattern is valid

How did you come up with that number 48? I need to know so I can generate addresses for other alt coins. What is the 48 in reference to? I attempted those flags on Windows and it didn't work.

https://en.bitcoin.it/wiki/List_of_address_prefixes

OK. So i attempted using the -X 48 flag and for the prefix I did Light and it just showed the help list of the tags. I'm using oclvanitygen. It isn't working.

It works, u just entered either invalid pattern or in the wrong sequence, so sad as if i helped u you would probably use it for your site, and no one will use my service at https://bitcointalk.org/index.php?topic=202826.0 to let me earn small income

What would be the regex to generate an only numbers address? And about how long would that take? Or is that even possible?

OK. So i attempted using the -X 48 flag and for the prefix I did Light and it just showed the help list of the tags. I'm using oclvanitygen. It isn't working.

Alphabetically "Light" is past the range of possible lightcoin (network 48) addresses. Valid addresses are generally in the range: LKDxGDJ-LiZZFKc7

You could search case insensitive, since "LiGHT" is still valid.

Code:

D:\Bitcoin\vanitygen-0.22-win>vanitygen -X48 -i Lightco
Difficulty: 1138380
Pattern: Lightco
Address: LiGHTcoirUn9XjtBqZWGyTf4o91RGerLZQ

I use flags

Code:

vanitygen -i-X48 Light
pause

But I just see this:

Code:

C:\DIRECTORY>vanitygen -i-X48 Light
Vanitygen 0.22 (OpenSSL 1.0.1c 10 May 2012)
Usage: vanitygen [-vqrikNT] [-t <threads>] [-f <filename>|-] [<pattern>...]
Generates a bitcoin receiving address matching <pattern>, and outputs the
address and associated private key.  The private key may be stored in a safe
location or imported into a bitcoin client to spend any balance received on
the address.
By default, <pattern> is interpreted as an exact prefix.

Options:
-v            Verbose output
-q            Quiet output
-r            Use regular expression match instead of prefix
              (Feasibility of expression is not checked)
-i            Case-insensitive prefix search
-k            Keep pattern and continue search after finding a match
-N            Generate namecoin address
-T            Generate bitcoin testnet address
-X <version>  Generate address with the given version
-F <format>   Generate address with the given format (pubkey or script)
-P <pubkey>   Specify base public key for piecewise key generation
-e            Encrypt private keys, prompt for password
-E <password> Encrypt private keys with <password> (UNSAFE)
-t <threads>  Set number of worker threads (Default: number of CPUs)
-f <file>     File containing list of patterns, one per line
              (Use "-" as the file name for stdin)
-o <file>     Write pattern matches to <file>
-s <file>     Seed random number generator from <file>

C:\DIRECTORY>pause
Press any key to continue . . .

Can someone explain the issue?

EDIT: Problem resolved. Space was missing between -i and -X48

[bitpop]

Maybe add a space

To start generating addresses with specific prefixes, while running on Windows, open up a command prompt, drag the VanityGen.exe into the command prompt, then type 1PREF1XyouWANT after it, then hit enter.

For example, type something like this into the CMD:
C:\Users\You\Desktop\VanityGen\vanitygen64.exe 1First 1Second 1Third 1Fourth

I wish this was explained somewhere, so that more know what they're doing. .

Ya that would be getting the ocl version to work is the hard part.

And it just goes on forever and ever. but if i do it with the cpu version it work for perfect in no time. i read through form and have not noticed any thing posted about this.

Same error here. Or almost the same, I guess.

Afaik there is a conflict with ATI driver which doesn't pop up on every driver version. You could try to downgrade/upgrade, but I'm looking for a real fix.

Try the 12.8 driver. That one works the best for everyone if you have anything under the 7950.

[infoporter]

I cannot get the GPU version to print a finished address out. It just repeats some garbage information and keeps looking. CPU genaration works fine. It would be great to generate these in Mkey/s than Kkey/s. HD7950 specifying my device number as 0:0, but after getting to what would be 100% it just keeps going and finds nothing.

It's an AMD driver issue. I get the same issues on my rig. 13.4 gives the GPU/CPU mismatch and 13.1 fails when building the kernel.

12.8 is one of the functional drivers.

OK, I will give it a shot.

[gadman2]

Can someone please explain to me the split key process? Basically just add the -e method and input the key that the person gives you and once you solve it give them the protkey? Is it that easy?

[vv01f]

you do not even need a protkey, thats just to protect the transfer

* create keypair (no specific target needed)
* provide public key in hex format (e.g. from ./keyconv -G)
* search difference / divisor for the target and your pubkey (e.g. -P option for vanitygen)
* after finding the needed privkey add / multiply it with your first privkey (e.g. -c option for keyconv)
* you got the vanity address

for more detail just read through https://vanitypool.appspot.com, also bitaddress.org is handy to do the combination if you used the pool.
if you have further questions after reading, point out your specific problem.

Unfortunately, you are talking a bit too tech savy for me in particular. I'm using oclvanitygen, rather than vanitygen. I do not see a keyconv file within these, nor am I familiar with it. I'm just looking for the method of solving a vanity address by using the split key that someone else provides.

For example I type:

Code:

oclvanitygen -d 0 -E [TheKeyThatTheyGiveMe] 1VanityWhateverTheyWantHere

And, when solved, it will give me a protkey. Do I simply give them that protkey and address and that's the end of it?

[vv01f]

For example I type:

Code:

oclvanitygen -d 0 -E [TheKeyThatTheyGiveMe] 1VanityWhateverTheyWantHere

This will result in a privkey ecrypted with the password [TheKeyThatTheyGiveMe]

the command option -P for vanitygen also works on the ocl version although it aint documented in the software (via --help) it is in this thread and in the switching functions code (line 225 of the pad, as part of main() )
the keyconv tool is precompiled in an older package of vanitygen (or compile it yourself)

dont -E, use -e instead that comment in help is there for a reason

(ocl)vanitygen will give you a private key (can be encrypted = protected private key), you're done when you have the 2nd part distributed to the "customer"

To be clear, this is not split-key generation. If you use the -E or -e option, you are just encrypting the address, but you still have full access to it, so this isn't secure for the other person.

As vv01f suggested, instead of -E, change that to -P (followed by their public key). You will provide to your friend the "PrivKey" that oclvanitygen will print out when finished. He or she can then use bitaddress.org to combine the two (their private key + this partial private key) to produce the final private key and address.

[eabedry]

Is something wrong with the pool?

I've found 2 keys according to oclvanitygen but when I go to put the privkey part into the web interface, I either get a 500 error or "Solution does not match the pattern".

[vv01f]

to test against that proposition
try to combine the two parts (offline with the script from) bitaddress.org (on tab "Vanity Wallet") yourself and find out if this is right (not fitting the pattern) that way.
the test you can do with the public keys as you should not have the first private key.
and make sure you submit a not encryptet private key, not a protkey and not a pubkey to the pool.

when you can make sure you are right and the vanitypool website is not you can contact them with that issue directly (there is an email button on the bottom of the website).

Yeah, I should have known there was an easy way to confirm the server side is broken.

I verified with bitaddress.org and have sent a private message raising the issue.

Thanks for the suggestion!
