2. Address

There is a script for php?

Are you sure you would prefer a typical server-side solution (php) for something that can also be done client-side (javascript) ?

BitcoinJs works well for this, and allows you to do it completely locally & offline.

Agreed, why does it have to be PHP?
You can get the JS brainwallet code as it is still available on github from previous commits.

JetRX: Depending on what passphrase you mean, try out https://github.com/Bit-Wasp/bitcoin-php. It's in composer too.

Some of the examples may be out of date, but an IDE will have you coding in no time.



Kazimir: Do you use electrum? That's python.. but on the client-side.

Important detail: what website/tool did you use to create the brainwallet? if it was brainwallet.org, use the github link posted above. The problem is there is no standardization for brainwallets, each tool works differently, some tools will give a different address + private key for the same brainwallet phrase.

By far the most common is to use this as your brainwallet:

private key = Sha256(passphrase)

This is also what brainwallet.org did.

That's insecure. For new brainwallet applications:

1) Consider if a brainwallet is truly necessary. If not, use more secure means. If it is, go to step 2.
2) Use a "slower" key stretching function with multiple rounds (to prevent brute force attacks), and use a long and secure passphrase.

I think it would be worth noting that simply a sha256 hash of a passphrase or word will not produce a user-friendly bitcoin private key, it would have to then be converted to WIF.

I almost never use php myself, I'm more of a python/javascript/perl/bash person, but I just have to point out for the record that you can run php in a terminal as a simple executable.  Just put it on your $PATH and call "php" with your php file as the first argument.  Say this is your file hello.php:

Code:

<?php
  echo "hello, world";
?>

Code:

$ php hello.php
hello, world
$

@OP, I hope anyone playing with brainwallets knows about this:
