Is it possible (for you) to add a feature similar to how the vanitygen exports to a file, but with only the privkeys, so that it could be easily mass-imported into Armory or using pywallet?

Just export the keys to a txt file and from there you can copy/paste anywhere.

I compared 0.17 to 0.19 but i see no speed difference.

Apparently, no speed improvements or performance-oriented changes to the kernels within the changelog.

Quote
Version 0.17, released August 8, 2011:
   - Bugfix for private key encoder, could create encodings not
     accepted by showwallet branch bitcoin
   - Remove oclvanitygen #pragma unroll by default, enable for NVIDIA
     (General performance improvement, hopeful resolution for crashing)
   - Oclvanitygen work size configuration tweak for smaller GPUs
   - New oclvanitygen add/subtract/compare functions for AMD Radeon
   - Add support for AMD BFI_INT instruction in oclvanitygen hash functions
   - Minor source code reorganization

Version 0.18, released July 4, 2012:
   - Support additive base public keys for outsourced address generation.
   - New oclvanityminer program, organized address miner for use with
     bounty pools, like ThePiachu's Vanity Pool.
   - New keyconv program for converting bitcoin private keys between
     wallet import format, password-protected format, and PKCS#8.
   - Support generation of simple P2SH (type-3) addresses.
   - Mac OS X makefile merged with Linux Makefile.

Version 0.19, released July 4, 2012:
   - Fix a potentially serious crash.
   - Remove oclvanitygen "-r" option.

If I export them to a file from within vanitygen, the output I get is:

and so on and so on. I don't think I can directly use those for importing, but instead I would have to individually copy and paste each privkey. And that is difficult Tongue
Perhaps I've used the wrong setting? (-o ./found.txt)

Thats right, if you have lots of keys generated, the copy/paste method is not very straight forward.

It's been a while since vanitygen has been updated.  I went through the earlier posts on this thread, and have tried to summarize the most common issues and feature requests:
...
The FAQ could certainly do a better job of explaining how to launch vanitygen.  Deepceleron, I really liked your earlier post, it has instructions that are very clear and concise.  If it's okay with you, I'd like to merge that into the FAQ.
Congrats on your return. You can use or re-purpose anything I wrote, with or without attribution. Thanks for your software!

Anything else?

When specifying a case-insensitive address prefix on the command line or in a text file list, you must still only use valid Base58 characters. This means you must only use lower-case i or o, and only upper-case L, or you will get an error.
  • Bad: 1celeron, 1CELERON
  • Good: 1ceLeron, 1CELERoN

This could be fixed so that if a case-insensitive search is being done, the user doesn't have to use correct case as input.

Version 0.19 seems to always crash when using the -X option.

Code:
% ./vanitygen -X
Segmentation fault

I know this because Tyler knows this.

Previous versions worked but 0.19 seems to crash everytime. It actually crashed the whole computer once.

This is what I'm using

oclvanitygen -d 0 1bitcoin

Using 6970 with stock settings on windows 7 64bit. Help, anyone Cheesy

Could be a problem with my GPU since CPU works perfectly?
I don't know, GPU mines normally with cgminer.

Are there going to be addresses that start with a 3?

Will the new version of vanitygen generate addresses that start with a 3 ?

My guess is that the kernel is only for AMD and the NVIDIA architecture isn't ideal for this kind of thing.

Now this is strange.  When I tried some things work, some do not:

C:\downloads\www.bitcoin.org>vanitygen -F script 3Biteme

BUT 3Test does not work

BUT 3biteme does NOT work

BUT 3Biteme does work, etc.

Certain things work, others do not

Can someone explain this to me?

Answered this in your other thread, but I'll repeat here.

The version "5" covers only the first half of 3-prefixed addresses. The rest are in version "6", with some confined to versions "4" and "7".

Agreed, but "isn't ideal" shouldn't equal "impossible"; I've got GPU-based miners running nicely on this machine, and I have seen previously in the thread other Mac users able to use their NVIDIA cards (so it's not "only AMD", though they had errors if they had a very low worksize parameter). Even if it's not ideal, I should be able to do better than the 600 Kkey/s I get with CPU processing of vanitygen on this box.

I can program in several languages, but OpenCL isn't one of them, so I have no idea where to start troubleshooting. Anyone with OpenCL experience able to tell me where I should start trying to solve this?

It isn't impossible, it is just that no one has written a kernel for it.  Infact it is my understanding that nvidia performs so badly in this type of operation that work was abandoned on it years ago.  But I am not a miner and I could be wrong.

Hi midnightlightning,

Sorry to hear it's having issues on your Mac.

How long did it run before you got this error message?  Did it make any progress?

Try running it with -v to get verbose output.

Unfortunately, I do not have any Apple hardware to test with, let alone do performance tuning.  Also, as near as I can tell, Apple has their own OpenCL stack that differs substantially from what one might find in the Catalyst or nVidia drivers on Windows/Linux.  So, you've hit kind of a sore spot right now.

My guess is that the kernel is only for AMD and the NVIDIA architecture isn't ideal for this kind of thing.

I think you're right about it in this case.  A back-of-the-napkin calculation suggests that a GeForce GT 120M @ 500Mhz with 32 CUDA cores should be capable of an upper bound of 650 Kkey/s.

However, for the record, primary development work on the vanitygen OpenCL kernel has been done using a high-end nVidia card.  It runs a lot faster on AMD hardware, but the nVidia platform doesn't receive any less attention for that reason.
