[ANN] CryptoLife UPWG - Universal Paper Wallet Generator

[Hazard]

Here's a universal paper wallet generator forked from bitaddress. If you set the corresponding decimal version, it'll let you generate a paper wallet for any altcoin out there. The decimal version refers to the the letter/number that a particular coin's address starts with. For example:

LiteCoin addresses start with L. So, the decimal version is 48.
NameCoin addresses start with n or m. So, the decimal version is 111.

The rest should be self explanatory. There's a few coins it won't work with, but ~99% of coins are compatible. This is a BETA and you should do the proper testing before sending any money to these addresses.

I can't believe nobody has commented yet on how awesome this is.

Now all coins have a new thing to add to their respective to-do lists: Create attractive artwork for the paper wallet.

You should get some Dogecoins for this

Doesn't appear to be working for Dogecoin. Has anyone else tried it? The client just highlights the address in red instead of sending the coins.

Can anyone else please confirm?

If you tried 30, try 31. And vice versa.

Thanks, this is great.

Please provide the source code so it can be executed offline and audited.

Is there any possibility to generate public keys to make a vanity address,  just as bitcoinaddress.org has a vanity tab?

Thanks,  awesome work.

Thank you for this great tool.

But wallet details don't seams to work.  When i try a private key created in first tab, it failed.

"The text you entered is not a valide Private key!"

Yeah, that tab is broken. It only works as a brain wallet generator right now.

Well, how about removing this from the script:

Code:

<script type="text/javascript">
var clicky_site_ids = clicky_site_ids || [];
clicky_site_ids.push(100658087);
(function() {
  var s = document.createElement('script');
  s.type = 'text/javascript';
  s.async = true;
  s.src = '//static.getclicky.com/js';
  ( document.getElementsByTagName('head')[0] || document.getElementsByTagName('body')[0] ).appendChild( s );
})();
</script>
<noscript><p><img alt="Clicky" width="1" height="1" src="//in.getclicky.com/100658087ns.gif" /></p></noscript> 

and also the server should not reject requests from wget:

Code:

This would be perfect if you could upload your own background. I guess I could manually save the html page and just change the image that way, but still.

[krach]

you can upload your own background, there are directions somewhere on the net

Wow! This is awesome! Thank you so much!
