Vanitygen

Sapientidiot:

'''Vanitygen''' is a command-line vanity bitcoin address generator.

If you're tired of the random, cryptic addresses generated by regular bitcoin clients, you can use vanitygen to create a more personalized address.
Add unique flair when you tell people to send bitcoins to 1stDownqyMHHqnDPRSfiZ5GXJ8Gk9dbjO.
Alternatively, vanitygen can be used to generate random addresses offline.

Vanitygen accepts as input a pattern, or list of patterns to search for, and produces a list of addresses and private keys. Vanitygen's search is probabilistic, and the amount of time required to find a given pattern depends on how complex the pattern is, the speed of your computer, and whether you get lucky.

The example below illustrates a session of vanitygen. It is typical, and takes about 10 sec to finish, using a Core 2 Duo E6600 CPU on x86-64 Linux:
<syntaxhighlight lang="bash">
$ ./vanitygen 1Boat
Difficulty: 4476342
Pattern: 1Boat
Address: 1BoatSLRHtKNngkdXEeobR76b53LETtpyT
Privkey: 5J4XJRyLVgzbXEgh8VNi4qovLzxRftzMd8a18KkdXv4EqAwX3tS
</syntaxhighlight>

Vanitygen includes components to perform address searching on your CPU (vanitygen) and your OpenCL-compatible GPU (oclvanitygen). Both can be built from source, and both are included in the Windows binary package. Also included is oclvanityminer, the vanity address mining client. Oclvanityminer can be used to automatically claim bounties on sites such as [[User:ThePiachu|ThePiachu]]'s [[Vanity Pool]].

Main discussion at [https://bitcointalk.org/index.php?topic=25804.0 BitCoinTalk]

For AMD Catalyst 13.1+ you need to run the AMD APP SDK Runtime from Catalyst 12.10 in order to get this program to work. (So all your Catalyst drivers would be brand new except for the SDK Runtime.) This is discussed on [https://github.com/samr7/vanitygen/issues/19 GitHub]. Linux users try [https://github.com/samr7/vanitygen/issues/19#issuecomment-28689948 this solution].

Also the latest source doesn't work properly for high-end AMD cards (7XXX and greater). Solution is to change line 459 in oclengine.c from: return quirks; to: return quirks & ~VG_OCL_AMD_BFI_INT;

== Expected keysearch rate ==
Main article: [[Vanitygen keysearch rate]]

What key search rate can I expect from hardware X?

Detailed list forthcoming. Some ballpark estimates are listed below.

Dual-core desktop CPUs, 32-bit mode: 100-250 Kkey/s.
Dual-core desktop CPUs, 64-bit mode: 150-450 Kkey/s.
Quad-core desktop CPUs, 32-bit mode: 200-400 Kkey/s.
Quad-core desktop CPUs, 64-bit mode: 300-750 Kkey/s.
NVIDIA GT200 GPUs: up to 6.5 Mkey/s
AMD Radeon 58XX, 68XX GPUs: up to 23.5 Mkey/s.
AMD Radeon 69XX GPUs: up to 19.5 Mkey/s.

As vanitygen performs a lot of large integer arithmetic, running it in 64-bit mode makes a huge difference in key search rate, easily a 50% improvement over 32-bit mode. If you are using a 64-bit edition of Windows, and not using a GPU, be sure to use vanitygen64.exe.

Radeon 58XX outperforms Radeon 69XX by a very comfortable margin. Oclvanitygen is sensitive to integer multiply throughput, and Radeon 58XX can multiply concurrently with other operations. At similar clocks, a hobbled Radeon 5830 will outperform a Radeon 6970.

In custom builds, CPU performance will be less than expected if the OpenSSL library is an older version (<1.0.0d) or is not built with the appropriate optimizations enabled.
