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

[willi9974]

Is it possible to put complete BTC adresses in the Präfix list and Not only a Part of a BTC adress?

But why? You'll never find it, and you can easily prove this to yourself by searching for only half the address:

Code:

./oclvanitygen 1P5ZEDWTKTFGxQjZ
Difficulty: 111848783584334965704335428
[8.59 Mkey/s][total 144703488][Prob 0.0%][50% in 2.861728e+11y]

If, after a couple billion years, you find a match for the first 15 characters, it only takes you (give or take) 1287559351899699065881753621004568 times longer to find the private key for the correct address.

But if you really want to try to brute force a funded Bitcoin address, you'll be much more likely to find one if you search for a long list of addresses at once.

yes i know that this is hopeless / practically impossible, but a technician wants to test something like this, just to play around...

vanitygen -seed option update:

instead of using seed plus random numbers have option to concatenate seed+n where n is a number that starts 1 to n times n has no upper limit such as seed1 seed2 etc.. and hash it using sha256(to_string(seed+n)) and convert that sha256 to address compressed and uncompressed format can you add such functionality ?

Well done - do you know How to sign a message?! and can you post that signed message here using the template:

Code:

-----BEGIN BITCOIN SIGNED MESSAGE-----
<insert message here>
-----BEGIN SIGNATURE-----
<insert address here>
<insert signature here>

Can I just ask why you chose that particular pattern?

I chose it because I read a lot about burning bitcoin and how it got stuck in my brain


Please tell me if this is correct

If you can sign a message via a wallet address then the chances for using that wallet address are slim at best - unless of course you were to dispose of the privkey and had never installed a wallet address into a bitcoin wallet ever.  There are more resilient wallet addresses that you can burn your crypto - another way to burn them is to donate them to a registered charity.

Has anyone put together (or started to put together) a list of CPUs / Video Cards & the speed you can get out of them.
I know it's a newer project and Jean_Luc is working VERY VERY hard on it so getting accurate numbers is going to be a moving target. But for now all we can do is look through the thread and see who is running what to get a general idea.
So far I have pulled from this thread:

Last updated 25-Nov-2019.

Actually i think especially in regards to the cuda version of bitcrack, the number of cuda cores for the specific card is really important, and there is actually a bunch of older cards with some great numbers here, for ex. the GTX 680 have 1536 cuda cores, which also happends to be the number of cuda cores for the GTX 770.

For comparison other cards cuda cores:
RTX 2080 TI - 4352
GTX 1080 TI - 3583
RTX 2080 Super - 3072
RTX 2080 Gaming - 2944

Provided that programs allocate memory with the full grid size. The grid's Y axis has been pegged to 128 for a long time until some newer cards introduced a 256-card Y axis. And some programs still assume a 128-core axis and have it hardcoded so clearly those aren't making use of the entire grid.

[Trancefan]

When i try to build to build the program in Win32, I get this error:

vanitygen.c(66): error C2057: expected constant expression
vanitygen.c(66): error c2466: cannot allocate an array of constant size 0
vanitygen.c(66): error c2133: 'ppnt': unknown size

The code is from:

vg_thread_loop(void *arg)
{
unsigned char hash_buf[128];
unsigned char *eckey_buf;
unsigned char hash1[32];

int i, c, len, output_interval;
int hash_len;

const BN_ULONG rekey_max = 10000000;
BN_ULONG npoints, rekey_at, nbatch;

vg_context_t *vcp = (vg_context_t *) arg;
EC_KEY *pkey = NULL;
const EC_GROUP *pgroup;
const EC_POINT *pgen;
const int ptarraysize = 256;
EC_POINT *ppnt[ptarraysize];

I haven't change anything in the code. How do I fix the errors?

The SSL library was updated, changing the way the BigNumber stuff works.

Hi,

I am fascinated by Bitcoin and found Vanitygen particularly interesting.

I think I understand most of how it works except for the split key generation.

I get how the process works, but I cannot understand exactly how the PrivkeyPart and the address are calculated as the PrivkeyPart is not the private key for the Address. So how are they calculated seperately?

If anyone could provide an answer it would be much appreciated.

Thanks in advance.

This old post may be the one you're looking for and I believe it's the process used by most vanity address generator including Vanitygen for split-key generation: Re: custom bitcoin address wanted.

This old post may be the one you're looking for and I believe it's the process used by most vanity address generator including Vanitygen for split-key generation: Re: custom bitcoin address wanted.

There are a couple of "wrong terms" used in that post that needs to be pointed out.

3) "less than the SECP256k1 generator" it should be less than secp256k1 order.

4) "reduce it modulo the SECP256k1 generator" again same mistake as above (it should be reduce modulo N).

"In ECDSA, you convert a private key to a public key by multiplying by the generator. Division is impossible." They mean reversing the process is impossible, not division. You can divide an EC point by an integer (ie. G/A = A^-1*G).

You can find the basics of the agorithm here:
http:<slashslash>gobittest.appspot.com/VanityAll

On this site your can combine both private and public key to generate new results.
It show you raw private/public keys as well as the generated bitcoin addresses.
It supports both addition and multiplication of the private keys.
Vanitygen only uses the additions methode because public keys can only be added.

Thank you so much guys for your help.

I do "get" the overall split key process, but where I'm getting stuck is exactly how Vanitygen generates the address? The SAME address that is ultimately created by combining the base private key and the privkeypart together. How does it do it?

[pooya87]

How does it do it?

With simple math. If upper case letters (P, Q and R) are points on the curve (aka public keys) and lower case letters (p, q and r) are integers in [1,N] range and G is the generator point we have:

Code:

P = Q + R
p*G = q*G + r*G
p*G = (q+r)*G
p = q+r

User has q (the initial number they generated) and receives r (the number pool gives them) from the third party and computes q+r or his private key for that final address.

P.S. p needs to be reduced to be valid. p = (q+r) % N

I have used this site and it's really helpful, but unfortunately doesn't answer my questions around exactly how Vanitygen calculates the address and the PrivkeyPart. The actual nuts and bolts of it.

I still don't think it's any clearer in my head.

Could you break it down for me as a process that happens inside Vanitygen rather than using math?

With regards to combining keys there is nothing more to it then can be found on the website.
The Vanitygen c-code itself just makes use of library functions to work with the generated keys.
The calls are all based on EC (Eliptic Curve) mathematics, where bitcoin just uses the specs according to SECP256k1.
https:<slashslash>en.wikipedia.org/wiki/Elliptic_curve.

Transforming a public key to a bitcoin address can be found here:
https:<slashslash>en.bitcoin.it/wiki/Technical_background_of_version_1_Bitcoin_addresses.

But I guess I probably do not understand your questions.
Are you looking for more information on how Vanitygen 'searches' for the BitcoinPrefix?

[BlackHatCoiner]

Could you break it down for me as a process that happens inside Vanitygen rather than using math?

Forget the maths mentioned above. Consider given that there's a way we can multiply a point with a number (which is the private key) and end up with another point. The new point's coordinates along with a prefix in the front consist the public key. That very public key is then hashed a bunch of times and with some extra steps we result in the Bitcoin address.

So the list of procedures, vanity implements is the following:

• Generates a random number and multiply it with a known point (called G) to get your public key.
• Takes that public key and hashes it to get an address. (Technical explanation)
• Repeats the above steps until the program finds an address that starts with the defined characters you want.
