How do I make a bitcoin address like holgero's?

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?

[Remember remember the 5th of November]

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://bitcointalk.org/index.php?topic=25804.0

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.

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.

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

Thanks! Worked for me. 12345678912345678912345678913HPoG2

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