vanitygen can't create namecoin addresses starting with the following strings:

Na, Nb, Nc, Nd, Ne, Nf, Ng, Nh, Ni, Nj, Nk, Nm, Nn, No, Np, Nq, Nr, Ns, Nt, Nu, Nv, Nw, Nx, Ny, Nz, NL, NM, NN, NP, NQ, NR, NS, NT, NU, NV, NW, NX, NY, NZ

however, others work
e.g.
./vanitygen -N NA

Privkey: 73Jru2KUsQRh7cpp1ba65sFFHUG77BSrWp8D3MxxKr6JMGtRYW9

./vanitygen -N Na
Prefix 'Na' not possible
Hint: valid namecoin addresses begin with "M" or "N"

It's kind of hard to compare 4553521 to 15058417127 if you don't have any separators. 4,553,521 and 15,058,417,127 are a lot easier to read.

Hello,

Getting a crash trying to start oclvanitygen up. I've got dual 6990m's, but just trying with 1 for now.

Otherwise, I'm hashing/mining with cgminer on my laptop no problem.

here's my output:

I'm a new user, like many who'll read the the vanitygen FAQ and it's not exactly clear why you don't need to resume vanitygen. Does it automatically save its progress to some file?

Password recovery tools like those from ElcomSoft have resuming as a salient feature.

I'm new to this and might be missing something but I can't get this to compile the kernel and run from Windows or Ubuntu Linux with my MSI R7970 (Tahiti) GPU running Catalyst 13 drivers. I can try to downgrade this weekend but I believe this is a real issue due to changes in their OpenCL?

Same basic error in linux.

Can you help me with the linux installation? I think I'm just a little to newby to successfully compile something on linux, so this is more a question than an issue.

When I type make I get the following output:

With ASIC's coming out soon I wonder how difficult would it be to implement?

Hey, thanks for your work on this awesome project!
I've managed to get it to compile in OSX but i can't get the open CL kernel to compile. Any ideas what might be up?

Hello friends, what is the best program for Windows to compile the project sources.

How about butterflylabs devices, it posible to use in vanity?

keyconv works fine for bitcoin addresses:

However keyconv incorrectly returns a bitcoin address when an address is generated for a different address version than bitcoin:

Privkey: 7Bqpv6dMiFX6m6CiXzk33CVNRVTJTziuFHf5NG2ZWvgq1mxF1dA

There seems to be no way to tell keyconv which version to use. None of the alt-coin generated addresses can use private key encryption because keyconv will not be able to properly decrypt them.

When I try:

./vanitygen -r "^1(.)(.)(.).*$"

I get the PCRE error: 0. I tried to fix this problem, but I was unable :/

What am I missing?

On August 20. I sent the following mail to Sam Revitch [email protected] and never got a response. I hope through this channel I will have more success.

Hi Sam,

I'm in the process of packaging your vanitygen for debian.
https://mentors.debian.net/package/vanitygen

Now I ran into a copyright issue.
http://lintian.debian.org/tags/possible-gpl-code-linked-with-openssl.html

I didn't know the AGPL before, so I did some research on the internet.
I'm not entirely sure, but I think it has the same incompatibility with
the openssl license as the GPL does.
So, for me to be able to make a debian policy compliant package, you
would need to add something along these lines to the copyright of
vanitygen:

In addition, as a special exception, the copyright holders give
permission to link the code of portions of this program with the
OpenSSL library under certain conditions as described in each
individual source file, and distribute linked combinations
including the two.
You must obey the Affero GNU General Public License in all respects
for all of the code used other than OpenSSL. If you modify
file(s) with this exception, you may extend this exception to your
version of the file(s), but you are not obligated to do so. If you
do not wish to do so, delete this exception statement from your
version. If you delete this exception statement from all source
files in the program, then also delete it here.

Is there a list of graphic cards that are supported with oclvanitygen?
Out of the three devices I tried, only one worked. I don't have the model here right now, but it's a GeForce, that's about three years old.
The ones that didn't work were:

• GeForce 9800 GT (about six years old)
• Intel 4400 (In a Dell XPS13DE)(brand new)

I'm not so terribly fluent with OpenCL yet, but for the intel card, I figured that the OpenCL driver doesn't support the kind of callback that's used. I tried without that callback, but that only got me one step further.
With the GeForce, I didn't look too closely yet. That's the output I get : vg_ocl_context_callback error: CL_MEM_OBJECT_ALLOCATION_FAILURE error executing CL_COMMAND_NDRANGE_KERNEL

Last month, I ordered a CuBox (http://imx.solid-run.com/product/cubox-i4-pro/) for use with oclvanitygen, as they write it comes with OpenCL. But after the experience above, I'm a bit worried that it won't work.

I just tried to generate Arkstone (ARS) address witch vanitygen.

 # ./vanitygen -X 23 A

Privkey: 65eW1eWAoehzHfa3hE83cSATkzpQ98Q9A79DUv4jAN6g4bwzSTn

when I try import this key, arkstoned give me error "incorect private key"
but validateaddress return "true"

When I dump privatekey from arkstoned all privatekeys start witch "E" not "6"

arkstone chainparams:

        base58Prefixes[PUBKEY_ADDRESS] = 23;
        base58Prefixes[SCRIPT_ADDRESS] = 83;
        base58Prefixes[SECRET_KEY] = 88;

maybe we need add params to set privatekey prefix ?

The OCL compiler is crashing on windows, and can be fixed by adding the flag -fbin-amdil to the compiler options. But I'm not sure how that is done in C code, as I have only tried it using AMD's KernelAnalyzer

I couldn't install the on OSX using ' make ', so @Habbie told me to remove these two lines in ' util.c ' file and then I could finally install vanytigen.

Hello, I got the error
pattern.c:32:10: fatal error: 'pcre.h' file not found #include <pcre.h>

After building/installing pcre 8.35 and openssl 1.0.1h.

To work around this, I first did:

ln -s /usr/local/include/pcre.h /usr/include/
and then in the vanitygen directory:
make CFLAGS=-I/usr/include

Perhaps you could improve the Makefile so this kind of custom setting isn't necessary.

My Makefile skills are a bit rusty, but it would be great (albeit not super important) if it were to check for the presence of the pcre library and if it's absent tell people to install it.

Without it you just get:

# include <pcre.h>```

On Mac it can be installed with `brew install pcre`

running into the following error when trying to "make"

Just wanted to confirm whether there is any reason behind not providing a brew formula for vanitygen. Is this intentional or will one be approved if created?

Is there a license for this project's source code? I'd like to add it to ohloh.net

I just spend a day writting standalone python script for importing/exporting keys (mostly based on bitcointools).
Probably it's the only alternative to showwallet patch so far (it works with the same private key format).
Specially for those who didn't manage to build showwallet, but knows how to set up python.
Options: --dumpwallet - dumps all keys in json format; --importprivkey= - imports private key from vanitygen

I would like to use this for other coins besides bitcoin, like PPC and ANC for example. Has anyone here had luck with modifying the code to do this?

This is partially because I didn't build openssl or pcre using emscripten yet.

Currently, keyconv $base58_privkey will generate and print the corresponding address for the private key, which is nice. What would be even nicer is if there were a flag (-p? -U?) that would cause keyconv to also print the full public key, in hex format (the way vanitygen -P $hex_pubkey takes it).

(keyconv -G already does this, but it always generates a new keypair.)

Based on this Bitcoin Stack Exchange question, I came up with a solution outside of vanitygen.

It'd be nice if vanitygen could take an integer parameter and generate that number of addresses. Output to a CSV file would be appropriate.

Generate an address using wildcards using the star char in the argument.

ie.

./vanitygen 1**_test**_git

Step 2 should prompt for the password and then spit out the privkey.

Observed Behavior
keyconv core dumps.

Am I the only person who seriously questions why this "Standalone" generator needs Open SSL? Maybe I'm missing something... It just seems fishy in this context... can anyone enlighten me?

Hi.

oclvanitygen.exe no longer works for me. I'm using a Nvidia GTX460, and I've tried both latest driver (344.75) and an one that a tiny bit older (344.11).

This is what I see in the console:

oclvanitygen64.exe -d 1 1test

[12.00 Mkey/s][total 249561088][Prob 61.1%][75% in 9.7s]

It just starts over like that until I kill it.

When I Google the issue, all I get is people talking about issues with AMD drivers. Since I don't use AMD, what could the problem be? I'd like to avoid downgrading graphics driver if possible.

EDIT: I should probably mention that I've tried oclvanitygen version 0.22 and 0.20.

EDIT 2: I should probably also tell you that I run Windows 7 x64.

I've encountered two problems with namecoin address generation, both with the prefix matching. Both of these were found using the Windows binaries for version 0.20

First, it says that certain Namecoin address prefixes are impossible when they are possible. I have seen this with NC, as below, N, and anything I've tried beginning with M:

C:\Program Files\Vanitygen>vanitygen64.exe -iN NC
Prefix 'NC' not possible
Hint: valid namecoin addresses begin with "M" or "N"

C:\Program Files\Vanitygen>vanitygen64.exe -iN NCoin
Difficulty: 4553521
Pattern: NCoin
Address: NCoinrjdvgjWXR81W6B9CNxT6tLgpAfZaj
Privkey: 74cKBhX2UWzutTPcvBvMDZA1HhSuVQ4NdLtU5VwmW4WnriN2fGW

The second issue is only probably a bug a bug (p < 1 in a million), but the case-insensitive match doesn't seem case insensitive for namecoin addresses: out of 10 addresses of the format NCoin that I generated, all with the -i flag, exactly 0 of them had a different capitalization despite there being two characters where this is possible (the C and the n).

I have installed the packages pcre and pcre++ with port, but it still complains it can't find pcre.h...

looris@Palace-of-the-Nine-Moons:~/ext-Sviluppo/vanitygen $ make
cc -ggdb -O3 -Wall   -c -o pattern.o pattern.c
pattern.c:32:18: error: pcre.h: No such file or directory
pattern.c:1604: error: expected specifier-qualifier-list before ‘pcre’

Using OSX 10.6

As written, calc_addres.cl must be in the current directory.

There should probably be a configurable option for this, as well as automatically searching a few sane default places such as $prefix/share/vanitygen/.

Hello how can i run this one week and i still search
Thanks ,
