pointbiz,
would you add wallet creation using coin.

To create a Bitcoin private key you only need one coin which you roll 256 times. Stopping each time to record the value of the coin. When recording the values follow these rules: head (of a coin) = 0, tail (of a coin) = 1. By doing this you are recording the big random number, your private key, in B2 or base 2 format.

People did that already, see http://www.liteaddress.org

Most altcoin supported at the moment is http://www.brainwallet.org

Lucky you! You can already do this.

1) click on "Wallet Details"

2) flip your coin(s) and record the results as 0's and 1's in the "Enter Private Key" field

3) click "View Details" and agree to have your 0101010... "key" used as a SHA256 hash.

Heya - how hard would it be to add BIP-38 for brainwallet addresses? You already have an implementation for paper wallet addresses, but adding it to brainwallets would dramatically increase security on them (imho).

I dont think that's possible as there's nothing to encrypt.

Huh? As far as I understand it, BIP-38 encrypts the private key? So confused right now, lol.

He means that with a brain wallet the private key is not saved/stored or printed anywhere. How do you encrypt something that is not there?

Yes in brain wallet your password is the private key essentially. Nothing to store.

In bip38 you must store an encrypted private key.

Should probably fix this. Also, wouldn't it be safer to write a browser addon where the entire java client side script lived?

A browser addon could be a good approach. How do you propose updates and checksums are handled? Who signs the plugin?

Crypto.cat does it https://crypto.cat/  after they gave up on server provided client side due to audit failures and packaged it all in an extension.
Firefox could sign your .xpi file using xpisign.py (with a certificate from a trusted issuer, such as whatever cert you have for your site) and Mozilla will check the update for malicious code and then distro the update. Chrome same thing can sign using your site's cert and openssl except Chrome autoupdates for extensions are shady. IE I have no idea, Safari no idea. Just Cinfu VM is kind of risky for trusting to generate keys, this way with an addon server doesn't matter.

I read that matasano article a long time ago but from what I remember it mostly does not apply to bitaddress because no external Javascript is loaded on the page. Javascript is Turing complete and bitaddress uses the same two validation techniques as all other open source software. Detached sig and checksums.

Just wanted to drop in to say thanks, I've used your site many times and I have 8 paper wallets printed from your site that I laminated and put in my room. Love it!
