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

I'm using Ubuntu and vanitygen on CPU works just fine. I've tried to use GPU but got the error:

Any clues? Mayve I did something wrong

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!

Dear odolvlobo,

downgrade your AMD Drivers to 12.8 , all versions above 12.8 have errors with oclvanitygen  

Unless you are using it in a VM, which means there is a problem with the VM GPU driver

Hi all.   I'm really surprised that vanitygen hasn't switched to generating compressed keys.

Uncompressed keys have public keys about twice the size of compressed ones and this means that when you use vanitygen produced addresses you end up paying more in transaction fees, causing more increase in blockchain size, etc.

I have modified my own copy of vanitygen to produce compressed keys...

Please upload your version of vanitygen. We will all be grateful for it. Put a disclaimer on your version if you don't like support or whatever, I am sure it will work just fine as is if the only modification was making it produce compressed keys.

AFAICT, he never did.  I dug around in the vanitygen code a bit and got it to spit out compressed addresses without too much difficulty.  I've put my fork up here:

https://github.com/salfter/vanitygen

As an added bonus, it'll generate Litecoin vanity addresses (compressed or uncompressed).  Since I'm not sure if script addresses can be compressed, I made script addresses and compressed addresses mutually exclusive.  Use something like this to get a compressed Bitcoin address:

Code:

vanitygen -F compressed 1

To get a compressed Litecoin vanity address, use something like this:

Code:

vanitygen -LF compressed Lfoo

I've checked the generated addresses against bitaddress.org and liteaddress.org; it looks like it's doing what it should.

Yeah, the code to change the format is fairly simple, just tweaking the OpenSSL parameters for point generation and adjusting a few buffer sizes. I decided to build my own miner for shoots and googles with CryptoPP, which is better documented, but has no built in ability to spit out compressed pubkeys. As far as  I can tell. So I had to do it the longer way.

Now we just need the pool to start taking compressed keys.

How do I compile that? or are there windows binaries already available?

[SonofBits]

Anyone know how to fix this bug I keep getting when I try to execute oclavanitygen on my GPU (AMD Radeon HD 7700)?

Running Windows 8 quad core platform

It and vanitygen64 run great in CPU mode but I can't coax it to run on the GPU at the higher hash rates.

Updated drivers and it didn't help and I have a new PC so can't revert back to anything older.

Great utility - would like to extend the preamble length to my vanity Bitcoin address.

Code:

git clone https://github.com/salfter/vanitygen
cd vanitygen
make vanitygen

This might works under Cygwin, but I've not tried it as the machines on which I run vanitygen all run Linux...you might need to pull in the PCRE and OpenSSL headers if you don't already have them.  Of course, you also need git, gcc, and make.  For git to work with HTTPS URLs, you also need the ca-certificates package (why this isn't pulled in as a dependency of git is anybody's guess.)

Attempting to build in Visual Studio is likely to be painful.

(Edited to reflect a successful build under Cygwin.)

I just tried downgrading to 12.8 but that immediately broke everything. cgminer, vanitygen both crashed immediately upon startup.
I first uninstalled my cards and deleted the driver via device manager, then used the ATI installer to clean up the rest. Then I rebooted and installed 12.8. Any ideas?

Yes, I did that, too, but either openCL-using program immediately broke. cgminer wouldn't even let me do -n and oclvanitygen wouldn't list platforms or devices. Could it be driver crumbs left behind somewhere?
