Vanitygen: Vanity bitcoin address generator/miner [v0.22]

[TheRealSteve]

Try with -r command. It is working for me.
[...]
it is better than nothing.

I disagree.

	-r (1a|1ab|1abc)	1a 1ab 1abc	1a	ocl -r	ocl 1a 1ab 1abc
complains about overlap	no	yes	no	n/a	yes
finds 1a	yes	yes	yes	n/a	yes
finds 1ab	yes	yes	yes	n/a	yes
finds 1abc	yes	yes	yes	n/a	yes
finds 1ax	yes	yes	yes	n/a	yes
Kkeys/s (example)	~150	~220	~220	n/a	~2800

So at the benefit of it not complaining about overlap, you lose a lot of performance compared to just the CPU version alone - never mind compared against the OpenCL version (which doesn't support regex).  And that would be the only benefit, as functionally it's still the exact same.  The only time there's a functional difference is if the prefixes are provided in reduced specificity order, e.g. '1abc 1ab 1a' - which is something a preparser could easily deal with before sending them to vanitygen.

remove return vp;
and replace it with ptrp = &itemp->ai_left;

And it doesn't even matter if I replace it with ptrp = &itemp->ai_right;

It works either way.

Thanks again.

Helou,

Could someone give some coding support for vanitygen (oclvanitygen)?
I'm using oclvanitygen (GPU) with Linux and I could compile a new version from source code.

So I need some advices for my "problem".
When oclvanitygen found ex "1GeGeA" pattern with -k option (Keep pattern and continue search after finding a match), now it's generate a new random seed and start again from different point.
I need to modify the source code that way, when it found a pattern, it does not generate a random seed value, only increase X value amount to "secret exponent value". So the starting point is quite near the previous one (diff X).

example:
Difficulty: 259627881
Pattern: 1GeGeA                                                               
Address: 1GeGeAAzBwzcPpCiMdGSURUBxLdSW3PFV3
Privkey: 5JpiwYTQZmKCtfumGP1wsZuZdfEvEBqSiEojSHh6QUPdM1a1pgV

This Privkey is hex and dec (=secret exponent):
84b05b4fff33236fe6f1e8d886d94fd8f4498d71ea0420d1902c90d9bf246bd5
60016891312021175057331173446731109351198050644514140408495846939253006429141

If X value is 12345678, next starting point is:
60016891312021175057331173446731109351198050644514140408495846939253018774819
Address: 1FwwNCewMPk8RsnzA528QSse3NjXuV6745
Privkey: 5JpiwYTQZmKCtfumGP1wsZuZdfEvEBqSiEojSHh6QbXg96Bfepr

Could someone please give piece of code for me? I'm quite noob to code.
I have look the source code, but it's quite difficult to understand.

Thank you very much!

I Guess what you are looking for kind of kills the purpose of the ECDSA algorithm.
The algorithms to find ECSDA points for addition and multiplications are not so straightforward to find points that are 'close'.
The result is also hashed with SHA256, creating a big change in the result for each minor change.
All the code you need for your problem is available, its called vanitygen, unfortunately >99% of the solutions/time is waisted.......

for an arbitrary altcoin, how do i determine the -X value (address family, eg: dogecoin is value 30)
to use in vanitygen ?
is there a standard place in the coin's source code?

Note that if you need to find the parameter for "-X", you can also check the coin's source.  It's usually in there assigned to PUBKEY_ADDRESS in one way or another.

E.g. for DogeCoin (30):
https://github.com/dogecoin/dogecoin/blob/master/src/chainparams.cpp#L132

Code:

        std::vector<unsigned char> pka = list_of(30);
        base58Prefixes[PUBKEY_ADDRESS] = pka;

For LiteCoin (48):
https://github.com/litecoin-project/litecoin/blob/master-0.8/src/base58.h#L275

Code:

        PUBKEY_ADDRESS = 48, // Litecoin addresses start with L

Keep in mind that each coin will have its own quirks in terms of disallowed characters (at certain locations), etc.

Edit: Dogecoin's had some changes - updated link to new correct line number.

Guys i have this error when i run oclvanitygen64.exe -v -i -D 0:0 1myaddress

Code:

Error loading kernel file 'calc_addrs.cl': No such file or directory
Could not open device '0:0', ignoring

But they are in the same folder!
How can i fix?
Win 8.1

[TheRealSteve]

You have to make sure that oclvanitygen is being run with its folder as the 'working directory'.  It's best to open a command line window (cmd), make sure you're in the vanitygen folder ('cd' on over if needed), and then run it / any prepared batch file you made.
If you're using a desktop shortcut, right-click it, choose properties, and make sure that the "Start in" field has the vanitygen folder.

If you need further assistance on this, detail exactly how and what you run so we can give a more targeted approach

Cd worked thank you!

Hi,
How can i "loop" the generator so he can create more and more addresses for me when he finished the first one? instead of checking the machine each hour/day to see if its over and then press "enter" again..

Tnx!

Use -k and you always use -o <name> to save the addresses and private keys generated to that file.

Eg:- vanitygen.exe -k 1MZakir -o asd.txt

great,tnx
where the txt is saved?

[TheRealSteve]

It should get written away to the same folder as the vanitygen executable.

If vanitygen.exe is on your path and your current directory isn't the dir where vanitygen.exe is located, then the file will be saved to the current directory instead.

You can tell it where to save the file by specifying the drive letter, example:

vanitygen -k 1Test -o d:\MyAddress.txt

If vanitygen.exe is on your path and your current directory isn't the dir where vanitygen.exe is located, then the file will be saved to the current directory instead.

And then they try to use oclvanitygen and have to jump through further hoops to avoid calc_addrs.cl not being found (see further up).  I'd personally just as soon discourage running any flavor of vanitygen outside of its own directory.

On Windows systems, perhaps. Windows was never known for its good file organization or path handling.

Ain't that the truth

It's working on Windows 8.1? I can not launch
