I may be doing this wrong, but can someone tell me why I got a Bad signature when verifying the latest windows 64 bit binaries with compressed key option for higher end graphics cards?

Code:
gpg: assuming signed data in `oclvanitygen.zip'
gpg: Signature made 10/24/13 00:45:00 Eastern Daylight Time using RSA key ID 223
C67C3
gpg: using PGP trust model
gpg: BAD signature from "Lifeboat Foundation <admin@lifeboat.com>"
gpg: binary signature, digest algorithm SHA1

I really don't want to find out my generated addresses are compromised after waiting days for a certain vanity address

Likely because the signature is invalid for the file - the sig is from about a week before the zip's date.  Probably just from a small change in the README, but there's no way to verify that.  I haven't noticed any suspicious activity, but I tend to use bitcoin things offline just in case anyway.

You can always try making the changes yourself; there's a bunch of comments from the lifeboat foundation ( https://github.com/samr7/vanitygen/issues/19) in the samr7 repo, as well as some posts here; https://bitcointalk.org/index.php?topic=301068.msg3581899#msg3581899

The user lifeboat doesn't appear to have posted in a while - projects_coordination at lifeboat.com is probably the e-mail address most likely to get you to the people involved in the build and this thread.

I guess I should have downgraded to lower drivers because my card broke last month. It should be coming back from repairs any day now.

Yes, it would be nice if this tool were updated to work with the latest GPUs, the AMD R9s, and the Nvidia ones too.

My dad said it got repaired and now he can pick it up. Hopefully by this afternoon. Unfortunately I'm never going to be able to use this address miners because I don't want to risk it again

Unless they come out with newer driver support.

For those who cant able to still run oclvanitygen, getting found delta, start delta.....
Just use driver uninstaller, i used this DDU from http://www.guru3d.com/files_details/display_driver_uninstaller_download.html.
unzip it in a folder in desktop, restart system in safe mode, run Display Driver Uninstaller.exe, select AMD-> Clean and restart.
It will remove all amd drivers & restart system.
Now just install 12.10 driver & everything works fine.
Did that, but still not work.

You aren't going to break video cards with drivers. You will break them by overheat though and lower the life running them at 100% usage (video cards run at a lower voltage and clock speed when they aren't doing work). The best advice is to keep them cool with lots of fans, and dust free by using case filters or regularly blowing or vacuuming the dust out of their heat sink fins.

I'm trying oclvanitygen on win7 x64 and running into a problem.

Here is what I'm doing:

C:\Users\User\Desktop\vanitygen-0.20-win>oclvanitygen -d 0 1Torza
Difficulty: 15318045009
Available OpenCL platforms:
0: [Advanced Micro Devices, Inc.] AMD Accelerated Parallel Processing
  0: [Advanced Micro Devices, Inc.] Barts
  1: [GenuineIntel]        Intel(R) Core(TM) i7-3770K CPU @ 3.50GHz
1: [Intel(R) Corporation] Intel(R) OpenCL
  0: [Intel(R) Corporation]        Intel(R) Core(TM) i7-3770K CPU @ 3.50GHz


I'm selecting -d 0 (have also tried -d0, without spaces) and get the same error every time. I have an AMD 6870 in my machine. What am I doing wrong?

Thanks!


EDIT: Doing oclvanitygen -D 0:0 did the trick!

how would be the comand line if you wanted to have more than 1 vga?
-D 0:0,1 ?
I have that doubt since i started here i have 2 7970 :p

-D requires a device string, you would be thinking of -d.  However, check if both devices are listed under the same platform, then you can just use the -p flag.

Maybe it's related to the fact that most people that want vanity address use a 3rd party website to generate it... and some such websites may keep the private key for their own later use.

It's safe if you create it within a secure computer not using any websites. For randomness, you can change your date and time.

Hey, Lifeboat!
This version of oclvanitygen is working really good with my 7xxx AMD on Windows 10. But I would like to run oclvanitygen on Ubuntu, to have a secure environment.
Is there any working oclvanitygen version for Linux, that works with OpenCL and an AMD Radeon 7xxx Graphic Card. Would be really nice.
(This is not just going to Lifeboat, if any other user knows a solution he/she is welcome to write it.)

Wish you all a great day Wink
