BitAddress.org doesn't generate the vanity address, it pieces together the vanity pool's part of the key which is generated for you, and your part of the key.

Yup, experimented with the site and came up to the same conclusion

Remember guys, if possible, use compressed keys.

why? how?

The transactions are smaller in size.

Remember guys, if possible, use compressed keys.

I use it to make hundreds of cold storage addresses to stash my coins. Also good for group buys, and games.

That is pretty cool, how long does it take to get a custom address?

Depends on the length of the prefix. 2 or 3 char prefixes should be very easy, you can generate hundreds in no time. the more chars in the prefix, the longer it takes.

Remember to always use splitkey generation if you outsource address generation. if they have access to the priv key they can steal your funds.

I get 8Mkey/sec on my GPU and 500K key/sec on CPU.
You'll get much better results on a GPU if your card works with oclvanitygen.
I can make 8 character names pretty consistently within a few hours on my GPU.

I get ~700Kkey/s on my CPU, but my (Nvidia) GPU is so old oclvanitygen usually crashes my display driver tying to free up enough cores to start, and if it manages to allocate a few (think ~5-10) I get about ~150-300Kkeys/sec. You're right about GPUs being better (most definitely, I'm going to upgrade soon), but I can make ~5-6 character names in a few hours on my CPU. Anything longer quickly stretches into weeks, months and years though. According to this, 5870s are the best GPUs for vanity mining at ~23.5Mkeys/sec.

I (and they) use a tool called vanitygen to generate the addresses. If you don't want to or can't build it from source, you can download trusted binaries from the link on its wiki page.

There is a way to generate vanity addresses without the generator ever having the complete private key, called split-key vanity mining. If you want a (very) basic explanation of how to get an address through this, or want to get one from me, check out my thread at https://bitcointalksearch.org/topic/vanity-addresses-6-7-characters-or-less-case-sensitive-ok-279914.

You can also request a vanity address at https://vanitypool.appspot.com, though I'm not sure how many people still work on addresses there other than me.

EDIT: How the heck does a line of text get duplicated within a post after clicking save? Double posts I understand, but that was weird.

thanks! will check it out now!

Also, if you're using a CPU on a 64bit system, make sure to use vanitygen64 - there's actually a significant benefit due to how it works:

Quote from: https://en.bitcoin.it/wiki/Vanitygen_keysearch_rate

As vanitygen performs a lot of large integer arithmetic, running it in 64-bit mode makes a huge difference in key search rate, easily a 50% improvement over 32-bit mode. If you are using a 64-bit edition of Windows, and not using a GPU, be sure to use vanitygen64.exe.

Vanity addresses are one of the few decent things you can still CPU-mine (and I do, personally), though it's only useful for short search strings at that speed.

Make sure to use oclvanitygen.exe that comes with that package or it will use your CPU instead of your GPU.
Example usage:

oclvanitygen.exe -o found.txt -k -i -p 0 -d 0 1MyName

-k = keep going after you find one
-o found.txt - save them to that txt file

And of course addresses have to start with a 1

Oh and if you have a newer card, it will fail. If it is broken on your GPU, it will say address found when it finds one, but prints no address! Test it out first on a really short string so it just finds it immediately, and make sure it prints the private and public key out, or you're just wasting your time.

BitAddress.org (https://www.bitaddress.org) also has a vanity address generator. It's client-side JavaScript, so the source is available, and it can be run while disconnected from the Internet for a little extra safety.

Yup! There is a way to make your own btc address but takes a long as i heard. I found someone who said he could make for me, but i don't trust him because he will already have the wallet.dat file Tongue
