Not sure what you mean. Do you mean you want the private key to be in another format? Title: Re: vanitygen Post by: FabioCarpi on January 15, 2015, 08:25:23 PM Not sure what you mean. Do you mean you want the private key to be in another format? yes. in pubkey compress formatstart with K or L Title: Re: vanitygen Post by: findftp on January 15, 2015, 08:38:24 PM Not sure what you mean. Do you mean you want the private key to be in another format? yes. in pubkey compress formatstart with K or L Oh, that's easy. Just take the output from vanitygen and go to wallet details at bitaddress.org. Code: satoshi@nakamoto ~/applications/vanitygen-master $ ./vanitygen -i 1fabio For security purpose you can even download the page and check the integrity on an clean (cd-rom boot) machine and run the page. There you can fill in the private key and see the compressed keys. WIF compressed: L11RLQpGgwpnin4jde2hXBmFgXa9d4bLkXj4D9QbSZexhdaf9R5m for this example. May I ask where you want to use the address?

Title: Re: vanitygen Post by: FabioCarpi on January 15, 2015, 09:20:11 PM my version dont suport the compressed format
Title: Re: vanitygen Post by: findftp on January 15, 2015, 09:25:58 PM my version dont suport the compressed format Mine neither.Did we miss something when compiling? :) Title: Re: vanitygen Post by: johoe on January 16, 2015, 10:33:48 AM my version dont suport the compressed format Mine neither.Did we miss something when compiling? :) I just checked. I use the version from Scott Alfter: https://github.com/salfter/vanitygen This is his commit that added compressed keys: https://github.com/salfter/vanitygen/commit/06c095e064b6fcf6fa609dc7b769bd0e60ac8336 Title: Re: vanitygen Post by: FabioCarpi on January 16, 2015, 10:58:32 AM where can i download the executable?
Title: Re: vanitygen Post by: findftp on January 16, 2015, 12:21:37 PM where can i download the executable? There is no executable. This works on linux. You have to compile it.Title: Re: vanitygen Post by: johoe on January 16, 2015, 12:34:25 PM where can i download the executable? I don't see precompiled packages. I can send you a linux 64 bit executable for Ubuntu, if you trust me that I didn't include any backdoor. If you have linux it is not so difficult to compile yourself. You need the usual C development packages and the library packages libpcre3-dev and libssl-dev. I just browsed around and there are many different forks of vanitygen and at least two different implementations for compressed keys.

but i have a bootable pendrive with ubuntu Title: Re: vanitygen Post by: Josef27 on January 16, 2015, 12:50:27 PM Atleast it still working, right?
Title: Re: vanitygen Post by: FabioCarpi on January 16, 2015, 12:53:33 PM yes
Title: Re: vanitygen Post by: johoe on January 16, 2015, 01:11:57 PM I put an archive with the linux 64 bit executable at

Edit: stripped executable, this changed sha256 sum. Title: Re: vanitygen Post by: HugoTheSpider on January 17, 2015, 12:30:30 PM Hello, if vanitygen searches for both; compressed and uncompressed keys at once, it should raise the key rate up to 100% because the expensive EC math has to be done once only for each PubKey double, AFAIK. Right?
Old (pseudocode): Code: for each (i ...) should turn into: Code: for each (i ...) Someone here which wants to give it a try and check if I'm right? I can't because I'm currently stick with a slow Windows laptop without a proper development tool chain. Title: Re: vanitygen Post by: johoe on January 17, 2015, 01:41:21 PM Hello, if vanitygen searches for both; compressed and uncompressed keys at once, it should raise the key rate up to 100% because the expensive EC math has to be done once only for each PubKey double, AFAIK. Right? I was always under the impression that vanitygen wouldn't do a multiplication in the inner loop but only increment the private key and add G to the public key. I'm no longer sure this is true. I hacked your suggestion and I went up from 560kKey/s to 720 kKey/s. Another thing to try is using positive and negative point. Negating a point is trivial for compressed key (xor the 2/3 with 1) and simple enough for uncompressed keys (negate y modulo N). Title: Re: vanitygen Post by: ChetnotAtkins on August 15, 2015, 09:10:57 AM I am interested in a patch for oclvanitygen that would enable simultaneous search for compressed and uncompressed keys.
Is this solution above applicable (if so, which file should be changed) or could anybody post the necessary code changes to enable this? Thanks a lot |
