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

[K1773R]

I'm not very familiar with C but I was going through the source code. I wanted to know where the address is generated.
Like, suppose I run vanitygen and it finds an address I want, I wanna know the line that prints the address and its private key on the console.
Thank you

grep the source for printf

grep the source for printf

I found printf, I want to extract only the bitcoin address from it because the output contains the private key and another line as well. Anyone knows how to do that?

many ppls know how to do this, but this is a so simple task so you can do it urself.

I can't seem to figure out the indexes in linebuf the address is stored in. Once someone tells me that, I'll figure out the rest myself.

And it just goes on forever and ever. but if i do it with the cpu version it work for perfect in no time. i read through form and have not noticed any thing posted about this.

I've come across this too with a full uninstall of newer drivers (removal tool) and downgrading to 12.8.

The only solution I can use to avoid the loop above is to run in safemode with the -S flag.

This does run a lot slower than normal.... however it is still a lot faster than my CPU.

Why would you only want the address? It's useless without the private key too?

[funkymunky]

Sorry for the "basic" question...

Is there a way to have the results found within the Windows version using the -k command be sent directly to a file?


Thank you

Thank you

Use the -o switch. Like
vanitygen -k -o filename.txt 1Dabs

Then go to sleep. When you wake up, you have a text file with a bunch of private keys.

If anyone is interested in generating compressed vanity addresses, see this Pull Request.  salfter did the CPU side, and I commented with a link to my fork that includes his work and adds OpenCL support for the GPU side.  Please be careful and verify that addresses you generate using my changes are correct before sending money to them.

Just got a chance to try out your OpenCL changes.  On my Ubuntu box, the new changes work like a champ.  I'm still trying to get a 12.x driver on my Gentoo box, as 13.1 breaks oclvanitygen. I just brought x11-drivers/ati-drivers-12.10.ebuild back from the dead, updated with some patches that allow it to run with newer kernels.  I have ATI driver 12.10 running on Linux 3.8.13, and with the 7750 in this box, the compressed-key oclvanitygen works with the -S flag (which it's always needed).

I've integrated your oclvanitygen changes into my fork.

BTW, those of you with Gentoo mining rigs might want to look at my overlay.  In addition to the older ATI driver, I have a bunch of ebuilds for Bitcoin, Litecoin, and some other altcoins in there.  (Haven't gotten around to a vanitygen ebuild yet, though...should probably fix that.)

Edit: One thing I noticed is that your oclvanitygen only appears to find Bitcoin keys.  The original appears to have the same behavior, so your changes didn't cause a regression.  Try this:

Code:

./oclvanitygen -D 0:0 -S -X 48 L

This should find a Litecoin key.  Instead, it runs forever. Is this a known limitation of oclvanitygen?

[jaywaka2713]

Code:

./oclvanitygen -D 0:0 -S -X 48 L

Use

Code:

./oclvanitygen -D 0:0 -S -X48 -i Light

You cannot have a space after the -X flag.

[scintill]

Use

Code:

./oclvanitygen -D 0:0 -S -X48 -i Light

You cannot have a space after the -X flag.

It seems to work with or without space for me.  But this example showed me the bug seems to be with certain (short?) litecoin prefixes, not litecoin prefixes in general.  Your example worked, as did Ligh and Lig, but Li and L just sit there hashing when they should be finding many addresses per second.  Lp worked even though Li didn't.  Can anyone confirm this?

I think i may have found a bug ..

Remove the space after the -X flag to change it to -X30. That will fix the script.

Hi,

Sorry if this has already been asked / answered.

How can I set vanity to generate random or a set of addresses based on a query and save all of the results to a text file?

Thanks,

Jack

I'm unsure if I understand your request, but say you want it to generate from a list.

Code:

1Bitcoin
1Whatever
1Example

Well you will put each prefix on its own line in a text file, place that file in the same directory vanitygen is in, and use the  '-f textfile.txt' flag. There is also a use for using the -f flag like this: '-f -' but I don't know what that does. Generates addresses from stdin, but my knowledge on that is limited.

[Teka]

I've been using this software for a while now and I have to say that its pretty good. Its a shame that it takes ages to create some vanity addresses.

if u want to use a set make a *.txt file in same directory as vanity looking like this

1fsvbfs
1fsafreaw
1fsgrsbvr

then use the -f flag >>> oclvanitygen -f file.txt

if u want vanity to write the matches to a file use the -o flag with a filename u want  >>>>>oclvanitygen -f file.txt -o testfile




Example command lines (oclvanitygen, device 0, default platform):

    Search for exact prefix 1ABCDE, keep searching after first match is found (-k):
    >oclvanitygen -d 0 -k 1ABCDE
    Search for prefix 1ABCDE in any combination of upper or lower case (-i):
    >oclvanitygen -d 0 -i 1ABCDE
    Search for ABCD anywhere in address (only supported on CPU vanitygen) (-r):
    >vanitygen -r ABCD
    Search for prefix 1ABCDE, use a seed file to make address generation more secure and random (-s):
    >oclvanitygen -d 0 -s RandomSeedFile.txt 1ABCDE
    Search for prefix 1ABCDE, keep searching after first match is found, and save all found address to a file:
    >oclvanitygen -d 0 -k -o GeneratedAddresses.txt 1ABCDE
    Search for many prefixes at once using a text file listing them (newline after each prefix including last):
    >oclvanitygen -d 0 -k -f PrefixList.txt
    Use all options above including case-insensitive search, and turn on verbose mode for more information:
    >oclvanitygen -d 0 -v -i -k -f PrefixList.txt -o GeneratedAddresses.txt -s RandomSeedFile.txt


When specifying a case-insensitive address prefix on the command line or in a text file list, you must still only use valid Base58 characters.
 This means you must only use lower-case i or o, and only upper-case L, or you will get an error.

    Good: 1ceLeron, 1CELERoN

I never got oclvanitygen to work on my GPU (only CPU which gets 750kkeys/s) so I read here that I should downgrade to AMD Catalyst 12.8.
So I did that, but still oclvanitygen does not work on my GPU:

I was getting a similar error from my 7750 when I was running it with 13.1.  It works fine with 12.10, though.  I'd give that version a shot.
