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

[apoorvlathey]

How can I login my generated Address?

You can use your generated address by using the Private key generated by vanity gen. Open a wallet like electrum or bitcoin core, enter your Private key into it and your address would get imported ! Now you can use this wallet to send and receive bitcoins to this vanity address.

I forgot my private key can I generate again?

You cannot generate the exact same address but can generate another address starting with the same letters.
Eg : If you forgot 1Example........ then you can use vanitygen to generate similar address staring with 1Example.....

If you had some bitcoins in that address then it could not be retrieved.

  that's not the asked question.

what do you mean by "login" ?  you mean watching or loading .. ?  

I forgot my private key can I generate again?

no. really impossible to get a coliision ( soooo improbable)

[Jezreel]

I forgot to copy the private key.

[defcon23]

I forgot to copy the private key.

man : already answered one post above: NO you cant.

[apoorvlathey]

I forgot to copy the private key.

To prevent this in future you can use the following code :

Code:

vanitygen64.exe -o file.txt 1Addy

This would save your generated address and private key into "file.txt" in the same folder where vanitygen is.

More info. I added some RAM to the system and it kept going for almost 2 days before crashing.
I'm thinking something in one of the windows updates is causing some kind of memory leak in the program or the driver, but that is a guess at best.

I'll throw in another 4GB stick later in the week and try again.

The computer doesn't need more Ram (all the work is being done on the GPU).  Have you updated your GPU's drivers?

OgNasty made a patch, search this thread for "LifeBoat"

That's the one I'm using.
I know system RAM should not matter, but @ 2 GB it will never make more then 18 hours. With 4 it makes it more then double that.

Latest NVIDIA drivers are installed.

-Dave

It's definitely something with system RAM
2 GB = 18 hrs before crash
4 GB = Almost 2 days before crash
8 GB = Over 3 1/2 days and still going....

However, I noticed that according to task manager it's not using that much memory. Very odd.

Also, dose anyone know the reason why it's using 50% CPU when all I have it doing is mining the the graphics card?

Thank you sir for helping me.

Does anything change if you increase swap-size? Memory leaks may be swapped away.
Alternative: take 2 GB ram and run oclvanitygen a few hours, then restart it. Repeat that and see if it crashes again.

Also, dose anyone know the reason why it's using 50% CPU when all I have it doing is mining the the graphics card?

Here it uses full CPU while mining on Nvidia. I assume it needs CPU to deal with the keys it finds or something. So the videocard just produces millions of keys per second, the CPU checks if they are the right keys. But I'm just guessing here

Edit: after reading shorena (see below) I am curious now what the CPU is doing

The GPU can check as well. See the comment here[1].

you only need more RAM if your on winblows. their mapping SysRAM with GPURAM.

Is there a way to lock/password protect the vanity generated priv key?

[xhomerx10]

Is there a way to lock/password protect the vanity generated priv key?

 You can use the -e option and be prompted for a password before generation.
Alternatively you can use the -E option and specify the password pre-generation (probably not a good idea for security reasons)

edit: If you don't have keyconv you wont be able to decrypt the encrypted private key.  Get it here and put it in your vanitygen folder.
  Usage: keyconv encrypted_private_key <enter>
  You'll be prompted for the password.

Is there a way to lock/password protect the vanity generated priv key?

After you import it into a wallet like electum, you can set up the relevant BIP38 pass phrase or simple password from there

[smaxz]

once, a priv key is shown though, its possible to import it anywhere. even if you have imported it to an encrypted wallet previously.

once, a priv key is shown though, its possible to import it anywhere. even if you have imported it to an encrypted wallet previously.

Thats why it is suggested to use the passwod option -e or instantly delete priv keys after importing.

Just a heads up...  I upgraded to AMD's 16.4.2 drivers and vanitygen no longer worked.  I had to downgrade in order to get it working again.

i have those drivers and it works, just tested it.

Code:

Interesting.  Mine would crash upon launching when trying to use the GPU (CPU worked fine still).  The GPU is a R9 390x.  I tried both 16.4.1 & 16.4.2.

Hard to make 7 Characters on address it takes several days.
