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:

* 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.

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.

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.

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.

Trade BTC for €/$ at bitcoin.de (referral), it's cheaper and faster (acts as escrow and lets the buyers do bank transfers).

I'm not very good with running command line stuff and lack of a helpful readme or sample command lines isn't helping my cause much Sad

I'm trying to create for myself a case sensitive vanity address using my gfx card.

If someone would be so kind as to throw up a sample command line that I could copy I'd be very grateful.

I want to +1 this because I too have been unable to get the kind of output I want.  Is it supposed to just generate a .oclbin file? What do I do with that?

Some days ago someone posted a Mac download for a vanity generator. I've had the thread deleted by the mods, but the poster was a brand new user and the only user who commented was also a new user. The software presents itself as a GUI to vanitygen, but in reality seems to harvest the generated addresses and keys, and upon receiving a certain amount of BTC the credit is transferred to a different address. I'm exposing this although it makes me look like a turd since it stole 14 BTC from me this morning.

The software can still be downloaded from https://github.com/trevory/bitvanity. I've downloaded the source and will look for some clues, but of course the precompiled binary can be something completely different.

In a moment of absolute stupidity and after having read about and being excited about vanity address generation, I generated a couple of addresses with this app and transferred some hard earned BTC into the address. Almost immediately all the bitcoins disappeared.

I've tried again with a much smaller amount and so far nothing has happened. It clearly triggers above a certain amount (the only other transaction to the receiving address is 2.09 BTC) in order to stay undetected. They may be using different addresses to receive and the limits might be variable or the thefts random.

The transaction ID is: ad46e931ff3ac203ed522c9fcba8a6b156ac4b0d73f3079b2b8e158d5e1be861

In the end 14 BTC lost, but a valuable lesson learned. Hopefully we can shut this scam down from the very beginning. If someone else wants to verify my findings, be my guest.

Obviously also now have to wipe the machine where I ran the software.

Edit: The source code version is clean and has nothing scary. I was hoping to find something in the compiled binary and found this, so it's very clearly malware:

Hmmmm this has me thinking of a new way to do cold storage.

Dowload a vanity gen to a pc. 
Disconnect PC from the internet. 
Generate a new address and private key. 
Keep a hard copy of the Address and private key, or perhaps on a usb stick that you only use on offline computers
You could then send coins to that address even though it wouldn't be linked to a wallet anywhere.
Then when you finally want to take the coins out, add the private key to a wallet at that time and away you go.

When I run vanitygen64, it operates at top speed for a few seconds (1.2 MK/s) then drops down to about half. This only happens usually while searching for 5 character prefixes (after the 1). Can anyone help me with this?
Windows 8 64 bit
AMD 8120 8 core


Also, how to use oclvanitygen? When I do
oclvanitygen.exe -d 0 1test
It just returns a list of devices. Help?

Does vanitygen work on alt coins like LTC, TRC, etc? I've never tried, wasn't sure if there was an option you'd need to use or just choose a prefix with the right number?

Run it in a command prompt to get the error if it just exits

I hope someone will post a version that generates compressed keys, even if it just on CPU, though I prefer GPU.

I can generate compressed keys using openssl, but is way slower than vanitygen. Uncompressed keys take more space in the blockchain...

I tried a vanity address gave it 3 1run and it finds it in minutes but as soon as its 1run7 it is taking days to find.  Why does it take so much longer to find or make a vanity with 4 after the 1 that all bitcoin addresses have?

What is your keyrate? Finding vanity addresses is a probability game. You may be just getting unlucky finding 1run7. Vanitygen should be telling you the cumulative probability that you should have found the address by now. Does it say 99.9%? Or is your hardware very slow and it got lucky finding 1run very early?
