I once found a program that was capable of creating Bitcoin addresses with specific words in bitcointalk bitcoin plus generate, but can't find it now. Is there a trusted program, in the Ubuntu repositories for example, that can generate these 'vanity' addresses?
I guess you mean Vanitygen: Vanitygen accepts as input a pattern, or list of patterns to search for, and produces a list of addresses and private keys. Vanitygen's search is probabilistic, and the amount of time required to find a given pattern depends on how complex the pattern is, the speed of your computer, and whether you get lucky.
You can generate a bitcointalk bitcoin plus generate address using various generators, such as Vanitygen for example. This option assumes you have a computer with decent GPU, as creating a long vanity address requires a lot of computation. If you don't have a particularly good piece of hardware and would still like to own a lengthy address, recently split-key vanity address mining became a bit popular. You can use online websites, such as my Vanity Poolto request a vanity address to be mined for you for a fee.
If you want to understand bitcointalk bitcoin plus generate this option is possible and risk-free, you can find the discussion of this problem on the Vanity Pool Bitcoin Talk topic. The vanity address site below was hacked in December,but the site owner only recently posted an update admitting the hack: More than 4 Bitcoins total have been stolen to date, as you can see from Blockchain records note the number of vanity addresses dumping coins, and you'll see that probability alone is proof, supported by all of the users who lost their BTC: The site owner has taken down bitcointalk bitcoin plus generate site, but for how long is up in the air.
As Stack Exchange keeps long archives, I wanted to make sure this warning stuck here for all to see, but did not want to edit the original response. You can also use https: Is secure as they never know the private key - see help on site for how this is possible! If you're tired of the random, cryptic addresses generated by regular bitcoin clients, you can use vanitygen to create a more personalized address.
Alternatively, vanitygen can be used to generate random addresses offline. The example below illustrates a session of vanitygen. Both can be built from source, and both are included in the Windows binary package. Also included is oclvanityminer, the vanity address mining client.
Oclvanityminer can be used to automatically claim bounties on sites such as ThePiachu's Vanity Pool. Solution is to change line in oclengine. If you have any problems with the binaries, join the relevant BitCoinTalk discussion. Bitcointalk bitcoin plus generate important options to know are -i and -r which cause the search to be case-insensitive and use regex, repsectively.
In its simplest format, you issue a command like:. Which tells vanity gen to look for an address with the exact prefix "1david. Using the -i option drastically decreases generation time. The -r option allows the specification of a regex value instead of the default pattern option. If, for example, I demanded that my address contain all lowercase letters but I don't care if the "D" in "David" is uppercase or not, I could use vanitygen.
One downside to specifying a regex prefix is that you will not be given any estimated time or probability data since such calculations are not as trivial as matching a simple prefix. The more specific your matching criteria and the longer the pattern the longer it will take to generate your address es. If you want to create an impressive vanity address, it might be easier to outsource it. As they use split-key address generation, you are sure that you are the only bitcointalk bitcoin plus generate of the private key.
The problem is if someone else manages to generate the same vanity address with the same private key, then bitcointalk bitcoin plus generate person will have access to your bitcoins. So I personally prefer giving out the "ugly" addresses as it would be unlikely someone else will have the private key to that one.

Bitcoin Stack Exchange is a question and answer site for Bitcoin crypto-currency enthusiasts. Join them; it only takes a minute: Here's how it works: Anybody can ask a question Anybody can answer The best answers are voted up and rise to the top. How can I generate a vanity Bitcoin address? It's really not very clear what you're asking for. A hash function, such as SHA or MD5 bitcointalk bitcoin plus generate a variable length input and returns a fixed length output.
The output is completely determined by the input, so for a particular input you can't "beautify" its hash. Well, I do not know. I found once sites that bitcointalk bitcoin plus generate that you can make "personal" bitcoin hashes. Perhaps, Bitcointalk bitcoin plus generate have mixed out things here. Perhaps, it was about personal hash generation, it should be possible!? But you cannot beautify bitcointalk bitcoin plus generate already-done hash? You must mean Vanity Addresses, right?
Still, I'm not sure what question you are asking. OK, that makes sense. Vanitygen generates random Bitcoin addresses over and over until it finds one that contains the word you're looking for. I once wrote a program to do the same kind of thing, and to keep all addresses that started with dictionary words. I found this while googling. It lets you select the prefix of your git commit hash when submitting a change: Vanitygen is a command-line vanity bitcoin address generator.
Guest 4 3. I don't recommend using an online website to generate private keys. Sure, the current code could do everything client side, but they or their hosting provider, or your Bitcointalk bitcoin plus generate, You could save the site locally, and use that, if you trust the code, though.
Hello nibor and welcome to the StackExchange. I assume you are the owner of that website. In that case, please edit your answer to indicate that you are affiliated with that website as per SE's FAQ - bitcoin.
I don't recommend this method. Currently the site does what it says. ECKey falseand verify the private key never was transmitted afterward form action. Get the source from GitHub. Proper syntax for VanityGen is: The private key may be stored in a safe location or imported into a bitcoin client to spend any balance received on the address.
In its simplest format, you issue a command like: The openSSL libraries aren't bitcointalk bitcoin plus generate properly even after Xcode is installed. You can fix this by running brew install openssl then running brew link openssl --force but you're still going to have errors.
Using brew, run the following commands: It's very unlikely that any randomly generated addresses will ever be the same. And you don't need to have the same private key as someone else to spend their coins. I'd like to second Chris's comment. The chance of someone getting the same address as you is 0 for all intents and purposes.
All the vanity generator does is generate a lot of addresses randomly looking for one that matches a pattern. The "ugly" addresses are no more random than vanity addresses. They both have equally insignificant chance of matching someone else's keys. I think the point the OP was trying to make is that you are effectively reducing the amount of entropy in they key when you generate vanity addresses.
The take-home from the comments is that you aren't reducing it by an amount that currently matters. DavidPerry you aren't reducing the entropy at all. Vanitygen tries random keys and throws away the ones which don't match your pattern. It has no less entropy than simply trying a single random bitcointalk bitcoin plus generate and using that one. The private key is still a random bit number in both cases. Sign up or log in Sign up using Google. Sign up using Facebook.
