is it possible to create your own DESIRED address?

[Simon8x]

Im using online generator. Its easier and faster for me http://bitcoinvanitygen.com/
My address: 1veLKroPwcYvWYv8vcGVJEajQAdnf7f7H

It seems to me that site doesn't offer split key vanity address. I would rather stay away with it for safety of my bitcoin.

Yes, it is easier and faster but not secure which is the important factor when using any type of currencies. Giving a signed blank cheque to a stranger. Don't ever use online vanity address generator. They do use split-key vanity address but after the address is made, an output is made. And they are fetching data's from output to show in the website. If they didn't delete that output file from the computer, they can see your private key which means they can spend your BTC anytime. They may not move firstly, but when your address get many mBTC, say 0.05+BTC, they may move the BTC to their wallet. The private keys can be retrieved from the server too. So please try to avoid such things! If you don't have enough computing power to create vanity address, create in the way, I suggested.

yeah,thanks for explaining, again!

yes, i know. the only reason i made this topic is that i was visiting eztv.it (a site that i was using for a longtime Smiley) and suddenly i saw their donation address and it was something like 1EZTV..... so i was curious to know how they did that

Not everyone is IT-tech expert, so they must trust some people/some businesses to receive what they want in IT world.
It would be perfect world where everybody would be computer security expert and would do everything by themselves, but this is reality, and people need help often.
( Which is not good for bitcoin overall, but there is no other way )

Oh! So you are the owner! Why are you telling "there is no other way?" Didn't you read what I and other people wrote? You either didn't see it or you are avoiding it.

P.S. For this I don't think a great knowledge is needed, just need a computer with enough power. Even a newbie to cypto can generate it easily, Samr7 has explained it in simple language.

Edit 2 : Your site is good and has a nice UI. It would be better if you accept public key part. So it will be secure. But it usually take more time to generate an address with that part public key than it is generated just with the characters/word.

as far as i found out about Vanity gen and its toppic here: https://bitcointalk.org/index.php?topic=25804.0
the address can be created offline and it doesnt seem to need any kind of special computing power!
also the source is available at github so..... i don't think it can contain any kind of shenanigans in the background

Yes, you can create it offline. What I meant by 'computing power' is that it needs to solve some expressions, so naturally your computer must be good. For me, with a dual core CPU+Nvidia GPU, I am getting ~220 Kkeys/sec when using Vanitygen-32bit, for some reasons, oclvanitygen isn't working for me, so my GPU can't be used for generating as I can only use vanitygen. If you don't have enough computing power, it is very hard to generate a vanity with 7+ charcacters and practically, impossible to generate a 9+ characters currently, it may change in future. I hope you understand!

i mean can i create any address that i like for example:
1POOYA87blahbalh(random)
----------------------------
EDIT: i got my answer, thank you all
found this thread : https://bitcointalk.org/index.php?topic=25804.0

Yes we can
Search for vanitygen

[Kakmakr]

So, I cannot throw the dice and choose random numbers for a private key, and then generate the public address from the private key?

Ah... I get it, you want a specific public address?

So if it's possible to generate your own public address, it should in theory be possible to hack it's private key?

I thought it was only possible to create your own private key, not your own custom public address? ^confused^

[aronnov]

seetahu I can not make a wallet in blockchain.info address in accordance with our will, because the system has a system blockchain.info random to make bitcoin wallet address, the address consists of numbers and letters, uppercase and lowercase letters, that's all I know .. .

Searching for a vanity address works this way:
1. Create a new public private key pair.
2. Check if the address fits your requirement.
3. Go back to step 1 if yes. Stop if no.

It is not going backward from the address to the private key.

[Kakmakr]

That is in effect what I am saying.

If you have someones private key, you can figure out what his public adress is, but not the other way around.

So how do you get the private key for a public address you designed yourself?

Does these Vanity tools only give you enough room to create, say the first 8 caracters, due to the lack of processing power to generate a full address?

You can find others private key using vanitygen by using the address. But now it is impossible, as it will take a lot of years. Even to generate a 10 char vanity addresses, it taked many many years, so you can easily guess how much years will it take to find a private key of 19 char vanity address. I hope you understand!

You can generate as many char vanity addresses as you want but now it is only possible to generate upto 9 char, which will also take a few days if you have a lot of GPU.

[Mobius7]

Yes.

So how do you get the private key for a public address you designed yourself?

Say for example, you want to have an address starting with 1ABC.
You create a new private key, the associated address is 1XYZ and you throw it away.
You create another new private key, and the associated address is 1234 and you throw it away.
...After lots of trying...
You create another new private key, and the assoicated address is 1ABC. You are happy with it, and import the private key in your wallet.

Does these Vanity tools only give you enough room to create, say the first 8 caracters, due to the lack of processing power to generate a full address?

The more characters you want, the lower the chance you will get a match (exponentially).
You can try to find an address starting with 1ABCDEFGHIJKLMN but it will be extremely likely that you can't get a match after years.

[Kakmakr]

It's acctually mind boggling how difficult it is, to match a full public address with it's private key.
Watched the video on youtube "Amazing math of Private keys" last night, and it's impossible to hack a private key.

Would be nice, if we could use Alias names linked to your Bitcoin address, to make it easier to remember. ^frown^

Take a look at this topic https://bitcointalk.org/index.php?topic=25804.0

[ferdinant]

How much you can choose from that desired address ?

[Muhammed Zakir]

How much you can choose from that desired address ?

Didn't get you, please specify. If you meant characters, then its your choice but longer it is, harder it is to generate.

Exactly. You can even run your vanitygen program trying to get my address, but then your success chance will be extremely extremely low, as there are a total of 2^160 bitcoin addresses.
