Start with a string that's roughly what you want. Base 58 decode it. Delete the last 4 bytes, call the remaining bytes s. Hash s twice with SHA-256. The first four bytes of that are your checksum. Append the checksum to s and base 58 encode it.

Thanks! Worked for me. 12345678912345678912345678913HPoG2

Dang! Nearly one whole bitcoin in that address. Such a waste. Someone needs to make a quantum computer to figure out the private key and put that money to some use! x.x

There's even more in this one: 1111111111111111111114oLvT2
Some algorithms apparently think that the RIPEMD-160 of their public keys is zero... Tsk-tsk.

That address would actually take billions of years to generate, it's valid, but the creator most certainly doesn't have the private key for it.

However, take a look at https://bitcointalksearch.org/topic/vanitygen-vanity-bitcoin-address-generatorminer-v022-25804

If you want to create an address exactly like that, sorry, I can't help you.

I know I can't make one where I have the private key. I just want a public key that works, like him.

(I mean just make a public key with the correct checksum)

We all know his address, right? 1BitcoinEaterAddressDontSendf59kuE
I want to make one of my own. (I mean just make a public key with the correct checksum)
How do I make the checksum work?
