My six-character custom address in my sig (including the leading 1) took about a minute or so with CPU mining, not even a GPU, so that's pretty darn quick.

Hi thanks. Suppose I wanted to generate an address for someone else? Then How do i go about it. I just don't understand the process. Can you please just give me a simpler explanation on how it works and a direct method of doing it. Thanks

I am also having another problem. I have two GPUs. How do I select a particular one?

Could someone please tell me the approximate time to generate an address that begins with 5-12 custom address. I have an Nvidia GPU. I want the time to generate addresses with 5 custom characters all the way upto 12 custom characters.

I had another doubt. Does it take a longer time to generate an address without knowing the full private key.

To generate a 5 characters address doesn't take that much. Try with your GPU and write down the average time spent. To generate longer addressess, just multiply by-50-60 that time for each character you want to add.

When you generate an address, you never know the private key, that's what you are trying to find.

How to install this in Ubuntu

I guess this is a question.

Anyway, you don't have to "install" it, just run it from a shell.

Download, unpack, run. Try to be a little more specific if you're having trouble.

Hello!

Thanks. I really liked it.
Can I generate a more complex one starting with MuhammedZakhir ?

Kindly,
Muhammed Zakhir

It will take far too long. Just try one part of the name instead.

You will need a lot of hash power, or a lot of luck. I think by the time being, it is almost impossible.
For every character you add, you need to multiply by 50-60 the time needed

OK

I'll offer a bounty for keyconv to work with BTC/LTC/DOGE/DRK for split key generation.

Check my repo @ https://github.com/kangaderoo/vanitygen
this keyconv should support the -X switch

Code:

./keyconv -c 5JVyzR3wUqJJB2aV7twThzs3HftVeZ2fH9rqpsGvWuTc76c1yFj 6JWNzw3CpQdqavm8XaNXNQVEn2bhc5aZwy8zkt4xf8B191Mf2e9

The Vanitygen updates are fixed to my development env. at the moment.
Build only the new keyconv code.

Have fun.

Does anyone know if this means that doge and litecoin split keys are not possible with this? or do I have to read through the entire codebase?

I checked the source code of the keyconv, it only combines two private keys an generates a new key.
For the address verification it assumes the prefix that is related to bitcoin, for some reason the -X option is not here for various address confirmations.
For combining the private keys it is actually not needed.

So I took your bitcoin adress to the site: http://brainwallet.org/#converter
convert the bitcoin to hex
input = base58, output is hex

Code:

1GHeVSRy4CiSnrCwydCJ3yMVJszpZfEELB ==> 00a7afd6658acf743094ad9458033b77ab2c4ead4572a7dfd4

replace the 00 prefix (bitcoin) for 1e (equal to 30.. I suppose dogecoin)
copy the result in the input box
input = hex, output is base 58

Code:

1ea7afd6658acf743094ad9458033b77ab2c4ead4572a7dfd4 ==> DLRk2hNcMccjKrPYiDBrbjX6C1j7tgjDpX

Inserting this private key in a Dogecoin wallet should give the prefix DLR I guess.....If the hashing is the same..
the generated code:
DLRk2hNcMccjKrPYiDBrbjX6C1j7r1Pnkg
is not 100% equal to the actual code
DLRk2hNcMccjKrPYiDBrbjX6C1j7tgjDpX

Thats because the SHA hash checksum is not calculated in prefix mode to gain time, this effect is only at the end of the address.

Correct - it always attempts to spit out a Bitcoin address. I only had a cursory glance at some of the forks, but it doesn't look like anybody actually touched keyconv to support altcoin addresses. BAU also doesn't support it, nor does bitaddress.org's code (though that's javascript, shouldn't be terrible to modify).

Looks like somebody should have things going, though;

Just as been done with (SHA256 and Scrypt) mining software, I've been trying to port the Vanitygen code for CPU to make use of the SIDM functionality.
By running the SHA256 and RMD160 4 times parallel (AVX1) I got a rough speed increase of about 25-30%.
It seems that the actual EC_key generation is the big time consumer.
Any idea how to speed this up?
Is it possible/faster to only calculate only a X-coordinate, hash the compressed key, and try to find a (valid) key-pair after a confirmation
a wanted prefix in the bitcoin address is found? You might run into false positives I guess, but this could be a trade off to faster hashing.....

Code is @ https://github.com/kangaderoo/vanitygen

The fact that they do not offer split key generation says enough.
Do not use http://bitcoinvanitygen.com/!!!

Yep. Hopefully its proprietor (Velkro? If not, I'd be happy to drop them a line at the e-mail address) can add split key generation, as aside from that it is fairly well-setup with concise instructions on how to import the keys, offering a paper wallet to print out, etc. VAMP ( http://vanityamp.com/ ) was almost like that, with a very polished interface, and based more on outsourced vanity mining (ala vanitypool) - that's still under reconstruction, though.

http://bitcoinvanitygen.com/ probably is using your software

Probably - nothing wrong with that either.

I do think the way it's set up might be problematic. For one thing, I'm not seeing a field for a customer to provide their split key part. That means that the service could (not saying they are, but they could) be holding on to the keys for the generated vanity addresses. Even if they don't, they could still get hacked and the hackers get access to keys from there (this has happened before with another service).

I certainly caution against this service's use until they implement split key generation.

Best to stick to one of the other services that do offer split key generation;
