Thank you for that obvious fact. I'm well aware of the break operator. I did that so I could copy the output.

It will happily hang at that screen indefinitely until I tell it to break.
Your welcome Tongue

I have no idea how this program works itself so my help ends there and now I leave you for someone else to help.  It's sortof like tech support asking if your printer is plugged in and powered on Wink

Sorry, I have a bit of a knee jerk reaction to people telling me obvious things. Kind of like when I'm giving tech support, and the person that came to me is trying to give me advice. 'Have you tried rebooting?'

Still dunno why the certs are buggered though. Along with the rest of the program.

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— and as a bonus it's about 15% faster. ... but I've only done CPU support, and at the moment I no longer have any ati GPUs (having sold off my GPU mining farm)... and I can't really justify putting in time to add support for features I don't need and thoroughly test it when I have so many other things I need to do for myself and others.

Are people still using vanitygen?

I'd like to use it, but I can't get it to work. It just hangs there like Kontakt said.

Are you distributing this?

I am. I am using it as a bulk wallet generator, and to have fun making short vanity addresses. But I prefer 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.

it works with Nvidia GPUs too or anything that supports OpenCL.
could you host your code @ github?

Ok. win32 second try, fully rebuilt:

https://www.dropbox.com/s/ikm9307wsx0ydqt/vanitygen_catalyst.zip

To build from source code:

download https://github.com/wyuzhe/vanitygen/archive/master.zip, setup dependencies, nmake -f Makefile.win32/win64 etc.

Once you'we built all the binaries (8 in total), you can wrap the result with AMD APP SDK 2.8 compiler which seems to produce correct code in case you're getting compute errors.

Beware that to get correct version of the compiler you need to download the whole SDK (200MB).

Test it against beta catalyst driver on system. In case you get a crash/your card is frozen, try removing some or all the dlls of compiler wrapper in 32/ or 64/ directory.

Wrapped version, when running with -v, should report:
Code:
Version: OpenCL 1.2 AMD-APP (1016.4)

Newer compiler versions produce incorrect results (block mining indeed unaffected - vanitygen kernel is nontrivial compared to simple sha256 one).

Detailed reports welcome as always.

Yuzhe, it doesn't seem to accept multiple devices, I guess opening multiple windows (and running them individual) is the only way to solve this? Smiley

To the user who requested vanity address 1CoLBRo: 

My miners found
  1CoLBRohNZyGDw6HhALzpjDDsZh7aj9Zr5
 and
  1CoLBRoNqYHbK71n2R3cyiQDUr31VAG57U

But my finds were after another miner on vanitypool found you an address.  If you want either of these additional addresses, send me a PM.

The updated version for Yuzhu seems to do it for me on windows 7, however getting mismatch on pre-compiled version, and having a lot of trouble getting it complied on MinGW... (got no real linux box close at hand)

I was using the precompiled rewrap that Yuzhu posted. It's that program that hangs.

You actually got keys? it works on mine, but gives bad output. (hence me needing to rebuild it from scratch)

To quickly see it, just set the search for the key really easy like 3 chars.

I was wondering what you guys thought of the idea of making a legitimate pool for vanity address mining.
I was looking into the code for it, and it seems pretty workable.
There just needs to be a way to do proof of work with vanityminer. It's the same theory as shares with bitcoin though, so not too complex.

I was looking into the code for it, and it seems pretty workable.
There just needs to be a way to do proof of work with vanityminer. It's the same theory as shares with bitcoin though, so not too complex.
They are already doing vanity mining, the main thing this new update is for is 7 series amd gpu's. And it looks great... I just need it to get producing keys... (managed to compile the linux version... now I just have to get that running somehow on windows...)

I was wondering what you guys thought of the idea of making a legitimate pool for vanity address mining.

I meant a legit pool with shared income and better allocation of resources.

You actually got keys? it works on mine, but gives bad output. (hence me needing to rebuild it from scratch)

Yep, the key I got out of it seems to be legit, for address 1dazzrAbMqNu6cUwh2dtYckNygG7jKs8S
