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

[LoyceV]

I have always wanted to do a vanitygen for my cold storage, but I am too paranoid the program would have some sort of built in preset way to make an address the creator also has keys for. How am I supposed to know for sure? I just wish I could trust do it trust-less.

If you're totally paranoid: use split-key:

Instructions
I can just create an address, and send you the private key. This means you have to trust me, my computer, my cat, both our email clients, and by definition it can no longer be used for cold storage. So let's not. Instead, use split key:
Step 1: Goto https://www.bitaddress.org/ move your mouse/type in the field until it shows 100% and wait a second.
Step 1.5: Optional but highly recommended. Download the page, verify the download and run it locally^*.
Step 2: Click Vanity Wallet click the Generate button next to Generate your "Step1 Key Pair"
Step 3: Reply to this thread with your public key and the prefix for your address. Save the private key somewhere safe. You will need it later when I generated your partial private key. Also, let me know if your preferred prefix is case sensitive, or any case is okay (the latter is much faster)
Step 4: Once you received your partial private key, go back to bitaddress.org and click on Vanity Wallet.
Step 5: Go to step 2 Calculate your vanity wallet. In the first field put the private key you saved and in the second field put the partial private key I gave you. Click Add and Calculate Vanity Wallet
Step 6: Copy the Vanity Private Key (WIF) and import it into your preferred wallet.

If something doesn't work as expected, have a look at this example.

In Step 3, you run vanitygen by yourself, and use your own publick key.

You can also use split key if you don't trust the computer that you use to run Vanitygen.

If I have pair privat-publick key for one of this list https://vanitypool.appspot.com/availableWork may i get rewards?
How split keys?

If I have pair privat-publick key for one of this list https://vanitypool.appspot.com/availableWork may i get rewards?
How split keys?

Yes, if you find the private key for one of the items in that list, you will get the reward listed. Use oclvanityminer for that, or oclvanitygen -P <public address> <prefix to search for>

If i found pair without "-P <public address>". I have clear private - public key. ?

Yes, but it won't be accepted as a completed work by the vanity pool. You can use it for yourself, though

What is so special about split-key? Even that might still have some sort of malicious code.

Guys, I use vanitygen plus with 1080ti and after several hours of work I get an error:

is anybody aware of a newer listing of expected keysearch rates than this (at least as old as 2015):

   https://en.bitcoin.it/wiki/Vanitygen#Expected_keysearch_rate

notable, inclusive of newer GPUs?

I'm not, but for a data point that's probably not on there, I'm seeing about 28 Mkeys/s from a Radeon RX460.  (Host system is Gentoo Linux with the AMDGPU driver and AMDGPU-Pro OpenCL layer.  I had to tweak calc_addrs.cl as described in https://github.com/samr7/vanitygen/issues/38#issuecomment-31248556 to get it to work.)

What model GeForce GTX 1080 Ti are you using and if you kill/restart vanitygen does it start working again properly?

This is what I use to kill a process if something severely locks up:
kill -9 `pidof oclvanitygen`

Is there a clue you can go on such as the temperature of the GPU dropping instantly when the program locks up?

102 Mkey/s here with a single GTX 1080 Ti 11GB 352-Bit GDDR5X

I agree, the list should be updated and it's way out of date.

Asus 1080 ti rog strix oc.
Yes, it does start working again with no problem, but after several hours this error repeats.

Why down calculattion in used more card.
Use 1 card. Showed 37-40 Mkey/s.
Use 8 cards at same task. Showed 225-242 Mkey/s. But if calculate must be 296-320.
Other big process not runned, only oclvanitygen and systems.
And card not used at 100 percents.

After several hours of work. Maybe an hour, maybe a day. The output of the current state stops.

But in the processes the task continues to be executed. It takes up part of the CPU time. And the calculation continues only on one of the cards. I tried to wait about a day, but nothing has changed.
After "^ C" it will stop after 20-30 seconds.

I have always wanted to do a vanitygen for my cold storage, but I am too paranoid the program would have some sort of built in preset way to make an address the creator also has keys for. How am I supposed to know for sure? I just wish I could trust do it trust-less.

If you're totally paranoid: use split-key:

Instructions
I can just create an address, and send you the private key. This means you have to trust me, my computer, my cat, both our email clients, and by definition it can no longer be used for cold storage. So let's not. Instead, use split key:
Step 1: Goto https://www.bitaddress.org/ move your mouse/type in the field until it shows 100% and wait a second.
Step 1.5: Optional but highly recommended. Download the page, verify the download and run it locally^*.
Step 2: Click Vanity Wallet click the Generate button next to Generate your "Step1 Key Pair"
Step 3: Reply to this thread with your public key and the prefix for your address. Save the private key somewhere safe. You will need it later when I generated your partial private key. Also, let me know if your preferred prefix is case sensitive, or any case is okay (the latter is much faster)
Step 4: Once you received your partial private key, go back to bitaddress.org and click on Vanity Wallet.
Step 5: Go to step 2 Calculate your vanity wallet. In the first field put the private key you saved and in the second field put the partial private key I gave you. Click Add and Calculate Vanity Wallet
Step 6: Copy the Vanity Private Key (WIF) and import it into your preferred wallet.
Credits to shorena for most of these instructions!
If something doesn't work as expected, have a look at this example.

In Step 3, you run vanitygen by yourself, and use your own publick key.

You can also use split key if you don't trust the computer that you use to run Vanitygen.

That's exactly what I do. I just use my normal computer but boot up a Linux Live USB to generate the one 'half' of the private key. Works perfectly! Although you can only do one at a time as OgNasty has pointed out in the past. For personal use it's not a huge deal though.

What is so special about split-key? Even that might still have some sort of malicious code.

I'm going to really dumb it down to the point that it isn't very accurate. If your partial private key is 0.....0001 and the next partial is X (your public key), what is X's private key? Who knows! Only you do! That's why it is a great secure option.

Guys, I use vanitygen plus with 1080ti and after several hours of work I get an error: CODE

Any ideas? Please help!

What model GeForce GTX 1080 Ti are you using and if you kill/restart vanitygen does it start working again properly?

Asus 1080 ti rog strix oc.
Yes, it does start working again with no problem, but after several hours this error repeats.

Interesting, I have the same card with that issue.  I wrote an auto-restart script to keep it to an extremely minimal amount of downtime, send me a PM if you'd like to try it out.

Hi guys.

There was such idea: if you want absolutely safe to generate the vanity address (outsource) it is necessary to use partial key. This is too expensive, you need to use all the processing power to generate one vanity address. My idea: use third-party services that will generate a private and public key (something like a certification authority center as GeoTrust, Comodo etc.). The public key will be used to generate a large number of vanity addresses, so they can be made much cheaper. In this case, the full private key can only be obtained using the private key of a third-party service.

Can it work?

I wonder why a CUDA version of OCL vanitygen never got made? Surely, it would better on NVIDIA cards.

Strange. I have oclvanitygen.exe and it's working great with my integrated Nvidia GPU on the laptop.

Already had some fun with the proggie...

The work of "A Performance Comparison of CUDA and OpenCL" says that the performance of the OpenCL core loses CUDA from 13% to 63%.

So, if you rewrite the utility Vanitygen on CUDA, you can significantly increase the speed of searching for vanity addresses.

Is there a way to get this to find Segwit P2SH (P2WPKH program inside P2SH) addresses?

[Zammo]

It would be great if this app could be updated to generate SegWit addresses
