vanitygen allows you to specify part of your bitcoin address.

Vanitygen allows you to specify part of your bitcoin address. It does this by repeatedly generating new addresses, and throwing away the ones that don't match. It has a companion program called oclvanitygen which achieves a massive speedup by using your graphics card instead of your CPU.

vanitygenminer connects to various vanity address pools and earns bitcoins by generating addresses and claiming bounties for them.

How does vanitygen calculate difficulty?

It seems really random. 1d is 1353, 1L is 22, 11 is 256, 11L is 78508, 11x is 78508, 111 is 65536, 112 is is 1335, 113 is 1330, 114 is 1330, 1L1 is 1330. I thought it was 58 to the power of the number of digits. Why isn't it?
