What is vanitygen?
Vanitygen is a command-line vanity address generator.
Download here: https://github.com/samr7/vanitygen
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 1stDownqyMHHqnDPRSfiZ5GXJ8Gk9dbjL or dogecoins to DMooNvsY5dJth17qop3RUUnZG3ta3MW2Ua. 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 took about 10 sec to finish, using my Core 2 Duo E6600 CPU on x86-64 Linux:
$ ./vanitygen 1Boat
Difficulty: 4476342
Pattern: 1Boat
Address: 1BoatSLRHtKNngkdXEeobR76b53LETtpyT
Privkey: 5J4XJRyLVgzbXEgh8VNi4qovLzxRftzMd8a18KkdXv4EqAwX3tS
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 ThePiachu’s Vanity Pool.

Main discussion at 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 GitHub. For Linux, use AMD APP SDK 2.7.
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: 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.
Vanity addresses for other crypto-coins
While all “normal” bitcoin addresses start with a “1” (one) (except multi-signature addresses that start with “3”), some other crypto-coins use different address name spaces. Vanitygen (as of version 0.22) can be used to produce vanity addresses for these crypto coins as well (but not for bitmessage addresses), by using the “-X” option. The following list provides some example command line calls and also indicates the address range for the respective coin (in ascending order of the “-X” parameter):
Generate Bitcoin (BTC), Devcoin (DVC), Freicoin (FRC), Terracoin (TRC) addresses:
$ ./vanitygen -X 0 1 -k
or simply just
$ ./vanitygen 1 -k
Generate Bitcoin (BTC) etc. multi-signature addresses:
$ ./vanitygen -X 5 3 -k
$ ./vanitygen -X 5 31 -k
$ ./vanitygen -X 5 39 -k
$ ./vanitygen -X 5 3A -k

$ ./vanitygen -X 138 xX -k
$ ./vanitygen -X 138 xZ -k
$ ./vanitygen -X 138 xa -k
$ ./vanitygen -X 138 xv -k
Generally, to find out the address format of a given crypto-coin (i.e. the number after the -X option of vanitygen) one can use this service:
http://darkgamex.ch:2751/q/decode_address/
Example: Take any Litecoin address, e.g. “LNipKabgGoTPnzhxsyFwTZdjVSXybjWucp”, and submit this URL:
http://darkgamex.ch:2751/q/decode_address/LNipKabgGoTPnzhxsyFwTZdjVSXybjWucp
The browser output will be:
30:265dcf8616a9723d3b4ba35c246b041e20013597
The 30 is Litecoin’s address format in hex (!), i.e. 30 (hex) = 48 (decimal) [because 316 + 01 = 48], i.e. use -X 48 in vanitygen to generate Litecoin addresses.
