Title: How do I make a bitcoin address like holgero's? Post by: leijurv on May 28, 2013, 12:38:24 AM 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? Title: Re: How do I make a bitcoin address like holgero's? Post by: Remember remember the 5th of November on May 28, 2013, 12:44:40 AM 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.

Post by: crary on May 28, 2013, 01:13:35 AM 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.
