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

[salfter]

I've made a vanitygen ebuild (for Gentoo) available:

https://github.com/salfter/portage

It's under app-crypt.  If the opencl USE flag is enabled, oclvanitygen is built as well.  The ebuild uses my vanitygen fork, which includes nonnakip's patch for newer Radeons:

https://github.com/salfter/vanitygen

So far, I've tested it on an AMD A4-3300.  oclvanitygen (using the latest fglrx driver in Portage) runs about 4x faster than vanitygen.

~/vanitygen $

didn't work still the program sees 1 vga only.

i did this to see what the programs sees:
~/vanitygen $ env LD_LIBRARY_PATH=./sdklib ./oclvanitygen -d 3:1 -k 1Nasty
Difficulty: 259627881
Available OpenCL platforms:
0: [Advanced Micro Devices, Inc.] AMD Accelerated Parallel Processing
  0: [Advanced Micro Devices, Inc.] Tahiti
  1: [AuthenticAMD] AMD Athlon(tm) II X2 270 Processor
~/vanitygen $

it sees 1 vga only? :/

Did you check the drivers? Is everything updated? Does your PC detects 3 VGAs?

   ~~MZ~~

(they are not in crossfire, i will try to install drivers again i think ). I dont know how to check in linux if the pc reads 4 vga. Is there any program for that? like... aida64? but for linux :p
i followed the guide in page 75, meaby is something wrong wrriten here:

# This is the procedure to get oclvanitygen running with AMD Raedon 7xxx
# on a fresh install of Ubuntu 64-bit. (tested with Ubuntu 12.04 and 14.04)

# install tools, dependencies and driver
sudo add-apt-repository "deb http://archive.ubuntu.com/ubuntu $(lsb_release -sc) restricted"
sudo apt-get update
sudo apt-get install build-essential git libssl-dev libpcre3-dev opencl-headers fglrx-dev
sudo reboot

# get source and compile oclvanitygen
git clone https://github.com/samr7/vanitygen.git
cd vanitygen
wget https://nastyfans.org/download/patch-oclvanitygen-amd.diff
patch -p1 < patch-oclvanitygen-amd.diff
wget https://nastyfans.org/download/AMD-APP-SDK-v2.7-lib-lnx64.tar.gz
mkdir sdklib
tar -xzvf AMD-APP-SDK-v2.7-lib-lnx64.tar.gz -C sdklib
make oclvanitygen

# run oclvanitygen (from inside vanitygen directory)
env LD_LIBRARY_PATH=./sdklib ./oclvanitygen -D 0:0 -k 1Nasty

Is it working now?
Is it the last "working guide"
Thanks

These have now been updated so that calc_addrs.cl gets loaded from /usr/lib/oclvanitygen and the object code generated at runtime from it gets saved to /tmp.  This makes oclvanitygen nearly as easy to use as vanitygen, as you don't need to keep these files in your home directory (or whatever).

Does this vanity gen still work?

That's a question that needs expanding.  What exactly are you trying to get an answer to?

Can you still run vanitygen?  Yes.
Can you still use vanity addresses?  Of course.
Can you still run oclvanitygen?  Might depend on your graphics card.  Works fine here.

I don't have any problem running vanitygen, ie it works for me.  Did you experience some issue with it?

sorry :/ meant no stealing no back doors.

and can it be used on mac:)

No back doors.  But this is an open-source program so you can download the source and see for yourself.  As I recall, I downloaded a source tarball and built it (I don't know if they distribute binaries).

As far as running on mac, I would guess you'll have luck.  I've only run it on GNU/Linux but given the *nix similarities I would suppose you'll be fine.

Better question is there a img file for mac already to run

thanks checking now. Appreciate the response.  I would pay for some one to do it since i would think it will take a while on a mac. but afraid of private key being used :/  any legit services out there?

Good questions!

The official repo has no back doors last I checked, which is a week-ish ago.  You'd have to do a diff between any of the third party ones. and the official one to double-check if any of those contain any changes other than optimizations/etc.  I do recommend using one that's more actively being maintained, like salfter's, or an earlier one like WyseNinja's

Although I don't know off-hand about any published OS X binaries, the source code comes with a Makefile that includes OS X support.  Should just be a matter of downloading the repo and running 'make'; though that may require further steps (alternative steps).

Well, yes, I don't know how to sort that out because if I or anyone else ran this program for you then by definition we'd be finding your priv/public key and you'd need to get that info from us. However, consider this: the vanity address you want will take longer (on average) to find the longer the vanity string is, BUT, you might just get lucky.  vanitygen randomly searches and so it's totally possibly (but improbable) to find a long vanity string very soon.  How long is the vanity string you're trying to find?  I was able to find 5 and 6 character vanity strings in a half day or so on a low-power, portable laptop.

Actually, yes.  ANY service that lets you use your own public key* in a split key generation method.
The split key generation method ensures that you can get your vanity address without the person generating it knowing what the private key for that address is, but you will know.  Vanitygen includes support for this.

* Note that this very specifically excludes any services that offer to generate that key for you.  Even if they pinkie swear not to store it on their servers or anything like that.

Thanks therealsteve, for correcting me there.  I had a feeling I had seen something of this sort before but I guess I discounted it without actually looking around.  ppreciate you setting the record straight and providing a link to the appropriate system (I'm reading about it now).

[TheRealSteve]

No problem

I haven't checked services lately, but these do accept split key generation using your own split key part:
https://vanitypool.appspot.com/
http://vircurvault.com/order/bitcoin/vanity/custom
https://bitcointalk.org/index.php?topic=270180.0

Example of a service that's doing it wrong, because they generate your part of the split key for you:
https://coinbit.tk/generate.php
Last I checked - which is almost a year ago now - they indeed did not send the key to their server.  BUT, here's why you still shouldn't trust services that generate your part of the split key anyway:
https://bitcointalk.org/index.php?topic=118968.0
( tl;dr: vanity address generation service operator says his site was hacked to send the split key part to a malicious actor's server, thus compromising the generated vanity addresses. )

vanitygen on mac works fine with a little tweak.

that might help:

What command I need to use if I dont care that is with big or small letters?

Like 1DogEatOneCatxxxxxxxx.....

But for me is same if that is like 1dOGeaToNECAtxxxxx.....



"vanitygen64.exe -v -i 1dogeatonecat " right?



What command I need use to get first letter big and all other from my word small but after that random letter is same big or small..? like "1DogeatxXXxxXXxxX....."
Whit command "vanitygen64.exe -v 1Dogeat" I get error:

Invalid character 'l' in prefix '1Dogeat'



Are that possible stop project and continue later without start again from base?

Yes.  (See 1st post)

What command I need use to get first letter big and all other from my word small but after that random letter is same big or small..? like "1DogeatxXXxxXXxxX....."

You would need to use the -r (regular expression) option, although I'm not entirely certain what you're trying to achieve.  It may also be more economical to supply a list instead so that you can use oclvanitygen.

Whit command "vanitygen64.exe -v 1Dogeat" I get error:
Invalid character 'l' in prefix '1Dogeat'

Weird - that shouldn't happen.  Are you sure you're not introducing a lowercase letter 'L' somewhere in your prefix?

Are that possible stop project and continue later without start again from base?

This doesn't apply.  It's basically a random process.  The "[Prob N%][M% in Xtime]" is a probability estimator, not a 'progress'

vanitygen problem it generate same address again
... removed crap ...

in this case, you have a serious problem.
either your PRNG implementation in OpenSSL is broken or your system RNG entroy sources is borked.
of course, both can be the case and are not mutually exclusive.

even worse, this is a good sign that very likely all of the crypto modules your software/OS uses will be weak! its not only vanitygen who is affected by this.
