Sorry for the newbie question but what happens if vanitygen throws up an address already in use by someone else? or did I miss the bit where is said it won't do this?
If it does, the resulting private key gives access to all the coins stored by this address.

The chances of it happening are so small it probably will never happen before the extinction of the human race even if Bitcoin becomes its primary means of storing and exchanging money.

Also, the private key may be leaked to your shell history file.  Kill your shell and shred your shell history file after importing.

How does one clean the shell history?

After importing the private key, run

Code:
history -c

And close that terminal window before someone can sneak up behind you and take a picture of the screen with a spy camera hidden in their bowtie.

Could somebody post an up to date vanitygen binary for OS X? I do not have have a fast enough connection to download the dev-tools right now. Thanks.

Same error. I should also point out that this only happens with the 64bit version so that just adds to the confusion.

Same problem here, but I get it with 32 or 64 bit versions.

Googling the error it's a standard SSL error response. Some solutions for other applications:

http://curl.haxx.se/docs/sslcerts.html

http://stackoverflow.com/questions/14566864/peer-certificate-cannot-be-authenticated-with-known-ca-certificates-how-to-reso

Verbose output:

Code:
* timeout on name lookup is not supported
* About to connect() to vanitypool.appspot.com port 443 (#0)
*   Trying 74.125.137.141...
* Connected to vanitypool.appspot.com (74.125.137.141) port 443 (#0)
* libcurl is now using a weak random seed!
* SSL certificate problem: unable to get local issuer certificate

Tried the ENV variables from this:

http://stackoverflow.com/questions/14286265/how-to-use-ssl-cert-file-for-openssl-windows-openssl-1-0-1c

with no luck. Also set PATH to the directory the .pem file is in. I'm betting Windows 8 is part of the problem since the earlier guy uses it also.

I started a thread to discuss ideas for pooled mining of vanity addresses. Please let me know if you have any ideas!

Hey guys. Im getting an error with Oclvanityminer64
This is the error:
Code:
Get work request failed: Peer certificate cannot be authenticated with given CA certificates

And this is the launch code: (On Win8 BTW)
Code:
ECHO Starting Vanity miner
oclvanityminer64.exe -u http://vanitypool.appspot.com -a 1CsMpcqmm9CDXU8j26E3w4iCdgt8Xbiqsi -d 0
timeout 30

Any ideas?

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.
If you are talking about actually mining PRE-EXISTING addresses in their full form, not just small patterns, sure, yes. But if you are talking about just patterns like 1MyAddy, then there is already a pool, it's http://vanitypool.appspot.com

That's not a pool, that's a joblist board. It's exactly like solo mining bitcoin. For people with low hash, it's useless. Vanity address mining is significantly more profitable that mining, in theory, but for me any of the addresses listed will take ~30 days for a 50% cdf. I can't mine for 30+ days with no return.

The fundamental thing that I'm saying vanitygen is missing is pooled rewards, with pooled mining. I was suggesting a pool that pays that same way a bitcoin pool does, with percentile shares per address. So everyone could be working on the same address simultaneously, and when someone gets it,the rewards are distributed to the miners based on work put in, rather than the current way of a bunch of people going solo, and one person getting the entire reward.

How would you structure a proof of work?
Mining vanity addresses is almost exactly what Bitcoin mining is. For Bitcoin, you're looking for a vanity hash; it must start with a certain number of zeroes. Addresses are, in essence, hashes. The proof of work, a partial match, is not really much different.

How would you structure a proof of work? My only idea is to accept partial matches to the pattern as proof if work, and pay earn a share percentage for that proportional to how "close" it is to the desired pattern. This seems complicated, but probably possible. I need to spend some time thinking about how the math would work out.

I've actually been working on building my own site for this recently, but have started by building it simply as a job list as well, to get that working first. I'm calling it a "market place" instead of a pool, since I think that name is more apt. I'm happy to hear any other ideas on how to implement pooled mining, while still minimizing risk for the pool operator. I might start a new thread for the discussion.

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
vanitygen (cpu only) works for me, oclvanitygen (gpu) gives crap output Sad 2 Mkey on cpu vs 28 Mkey on gpu... so wish I could use my gpu.

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

I downloaded the version at https://www.dropbox.com/s/ikm9307wsx0ydqt/vanitygen_catalyst.zip yesterday and it works on my machine, haven't tried building from source.

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