Vanitygen to search for numbers

[SAMKUSH]

I have vanitygen running on my pc and I was wondering if there was a way I could search for something like the first 8 characters must be a number but any number is ok. I can only see an option to search for an exact number or a set of characters.

This is very easy.  Vanity gen uses regular expressions.  Just start VanityGen and type this at the command line:

Code:

vanitygen64 -r 1[\d]{8}

 You should move this to beginners and help section.  See link at the bottom left for move topic

You have to use regex so use the -r switch but it doesn't work with OCL so you will lose speed.
This will find occurrences of exactly 8 numbers in a row but it will appear anywhere in the address

Code:

vanitygen -r [1-9]{8}

You could try a leading one like this to get the beginning of the address

Code:

vanitygen -r 1[1-9]{7}

but that will not always show up at the beginning.

I think the ^ character represents the start of a string but I can't seem to get it to cooperate.

Code:

vanitygen -r ^[1-9]{8}

Thank you for your help, I will try this out and see if it works.

 I like this method!  It is much more concise than what I showed you.  Still you may get a result which is not at the beginning of the address.  Also you can save the output to a file and use the -k switch so it will continue generating addresses of the specified format.

Code:

vanitygen64 -k -r -o filename.txt 1[\d]{8}

Use ctrl-c to stop the program.

The problem I am having right now is that when I use -r it does not estimate a time to reach 50%. The pc I'm using is old so I would need that to know if I'm wasting my time on an address that would take years to find.

Is there a calculation I could use to work out how long or is there an easier way?

Shoot because I put the leading 1 combined with {8} it is looking for a 9 number sequence beginning with 1
change it to

Code:

vanitygen64 -k -r -o filename.txt 1[\d]{7}

for 8 numbers
or even

Code:

vanitygen64 -k -r -o filename.txt 1[\d]{6}

for 7 numbers if it still takes too long.

[xhomerx10]

It shouldn't take years.  At approx. 600 Kkey/s I can find 34 addresses with nine digit runs using

Code:

vanitygen64 -k -r -o filename.txt 1[\d]{8}

Maybe you can use those numbers to figure out your time.

I'm running at 3.1Kkey/s, like I said, I'm using a very old PC, I will probably run it on a different machine and see how that goes.

 So it should take you about 5 and a half minutes per address with a 9 digit run.  That's not terrible.  Just let it run and walk away for a while.
Drop it back to searching for 8 digits and you should be able to find about 1 every minute.

I have left it for the past half an hour now and there is no file, do I have to create it first for the address to be stored in or will it be made when an address is found?

So far it says I have searched 10 million addresses

There is no need to create the file as it will be created as required.  You don't see anything else on the screen?

I see nothing on the screen, I will try search for 4 numbers just to see if I get an address

EDIT: I have just searched for 2 numbers and it comes up on the screen but no file is created

Maybe you can use those numbers to figure out your time.

I'm running at 3.1Kkey/s, like I said, I'm using a very old PC, I will probably run it on a different machine and see how that goes.

 So it should take you about 5 and a half minutes per address with a 9 digit run.  That's not terrible.  Just let it run and walk away for a while.
Drop it back to searching for 8 digits and you should be able to find about 1 every minute.

I have left it for the past half an hour now and there is no file, do I have to create it first for the address to be stored in or will it be made when an address is found?

So far it says I have searched 10 million addresses

 @ 10million, you should have found 7 or 8 by now.  That's odd.
There is no need to create the file as it will be created as required.  You don't see anything else on the screen?

Thank you very much for your help, I think I have got it to work now. My only other question is do you know how many addresses I will have to search to have 8,9 10 digits in a row etc. to reach 50%.

 Shorena

 Thanks for the tip! I'm going to try ^^ now

 SAMKUSH

[596.32 Kkey/s][total 39999267][Found 35] <---9 numbers
about a million keys per address

[632.33 Kkey/s][total 94099468][Found 12] <---10 numbers
about 8 million per address

[622.72 Kkey/s][total 400913991][Found 7] <---11 numbers
about 57 million per address

 I guess probabilities were too complicated to compute when using regex so it wasn't implemented in vanitygen but the above should give you can idea based on your computer's speed.


edit: I forgot about 8
[611.76 Kkey/s][total 12742494][Found 94]
about 135 thousand per addresse

Thats really low speed, you should consider outsource'ing this job.
Generating keys on CPU is really bad idea tho, other way to do it is to invest in some good graphic card and use it for generation.

I'm running at 3.1Kkey/s, like I said, I'm using a very old PC, I will probably run it on a different machine and see how that goes.

Thats really low speed, you should consider outsource'ing this job.

 You cant use the graphics card while using regex so CPU is your only option.

 Thanks for the tip! I'm going to try ^^ now

 SAMKUSH

[596.32 Kkey/s][total 39999267][Found 35] <---9 numbers
about a million keys per address

[632.33 Kkey/s][total 94099468][Found 12] <---10 numbers
about 8 million per address

[622.72 Kkey/s][total 400913991][Found 7] <---11 numbers
about 57 million per address

 I guess probabilities were too complicated to compute when using regex so it wasn't implemented in vanitygen but the above should give you can idea based on your computer's speed.


edit: I forgot about 8
[611.76 Kkey/s][total 12742494][Found 94]
about 135 thousand per addresse

Thanks for that this has really helped me out.

Code:

vanitygen -r ^[1-9]{7}

This gets me only about 90 kkey/s.

Correct. As an alternative, you can work around this by creating an input-file that contains all possible numbers you want to search. I've tested it, and it gives me 3.4 Mkey/s using oclvanitygen.
But with a 40 MB inputfile (8 digit numbers from 11111111 to 19999999, excluding the ones with a 0 in it) oclvanitygen already consumes 2 GB memory, and it tells me WARNING: better match throughput is possible using vanitygen on the CPUvanitygen might be faster for low difficulty.
I tried to upload my input-file to pastebin, but my laptop ran out of memory copy/pasting it.

To summarize, using an input-file might much faster if you want addresses with 9-10 (or more) digits at the beginning of the address, but your system needs to have a lot of memory.
