Blockchain.info has now added Brain Wallet support with the same format.
I'm not seeing it. Where can I find the brain wallet support on blockchain.info? Thanks. I had the same problem at first. It didn't show up on Import/Export. I had to try force it to fully reload and then it showed up. But first couple times I tried it wasn't there. Which is a bit odd but perhaps something isn't quite right with cache handling and FF doesn't load the new version.

Thanks, that was it. Control-Shift-R in Chromium fixed the problem the 2nd time I tried it, though I had to log in again.

Sorry, if this was answered somewhere I missed.... If I get public and private key pairs, that I have never used before, is there a way to check their integrity without spending the Bitcoins? I'd hate to think I have a good paper wallet stored somewhere but then find out there was some computer glitch, typo I made writing them down, or printer issue that screws up an address and makes the BTC no longer spendable. It'd be nice if there was a way to check these pairs are good, entirely offline.

You can test them with Casascius Bitcoin Address Utility ( https://casascius.com/btcaddress.zip). BUt you will encounter more risk entering them into the computer within the reach of malware, than you ever will on the account of the private key being wrong! As a test, I generated 10,000 addresses with BitAddress.org and verified them with my utility, which comes from a completely different codebase. 100% of them were correct. This is something I don't worry much about.

Companies claiming they got hacked and lost your coins sounds like fraud so perfect it could be called fashionable. I never believe them. If I ever experience the misfortune of a real intrusion, I declare I have been honest about the way I have managed the keys in Casascius Coins. I maintain no ability to recover or reproduce the keys, not even under limitless duress or total intrusion. Remember that trusting strangers with your coins without any recourse is, as a matter of principle, not a best practice. Don't keep coins online. Use paper or hardware wallets instead.

I made a fork/addition to bitaddress.org that allows easy printing of blockchain.info wallet exports. If this is interesting/useful to you then you can read more here: https://bitcointalk.org/index.php?topic=105066.0EDIT: I have updated the script to be a generic Export (to QR) option. It supports the original BCI wallet export as well as vanity gen output now.

Thanks to a post by Jerry Brito, I learned that just like how you can turn a .jpg into a data: so that your images can be included in the .html file, I see that the entire html can also go in as a data. Here's his blog post: - http://jerrybrito.org/post/31469161810So I was able to make a Data URL / link using the .html served by BitAddress.org into an URL that does not require any web server or locally stored .html file. [Edit: Bah, this forum's url= forces an http:// so links with data: are not usable here after they get prefixed with http:// so I can't show an example. Here's a paste of the data: URL for a Hello World page. That data: can be selected and copied, then pasted in your browser's URL field. - http://bitbin.it/raw.php?id=KnRQtiAj ] But this provides a solution to a problem I saw. For a device that is essentially has security locked down with no local storage, I then can't just save the .html to allow me to generate a paper wallet after disabling the device's network connectivity. And without network connectivity I can no longer access the web site to get the .html that way either. But I can receive e-mail messages (though attachments are not supported). Those previously received e-mail message are accessible even after disconnecting the device's network connectivity. So using this Data URL method I now have a way to load the html that was originally from BitAddress.org without having either a local filesystem or network connectivity. Here's the service that makes the data: URL: - http://dataurl.net/#dataurlmaker

Make sure they don't sneak in some code to report your keys back to them (or make your keys not very random, etc.). ![Wink](https://bitcointalk.org/Smileys/default/wink.gif)

But all the elements and javascript can be verified as being identical. ) Obviously I wouldn't trust this Data URL if I received it from anyone else but if I created it and validated it wasn't altered I would trust using it myself the way I described (from my own e-mail). Point taken though ... for larger amounts I would only load a bitaddress .html directly where I know it has not been tampered with. Using this data url, any tampering would be harder to notice.

As an aid to VanityPools I have created a new version of bitaddress at: http://bitcoinstatus.rowit.co.uk/other/address.htmlwith a new tab "Vanity Private Key". I have just put it there for comments etc... Requirement was to get keys in different format (mainly to stop users getting confused!), and to be able to ADD two private keys together. See: https://bitcointalk.org/index.php?topic=84569.0for why this is needed. Maths I have tested against: http://gobittest.appspot.com/VanitySumthat I am assuming is correct. This is my 1st hack at bitaddress.org so feel free to correct my bad coding - is a bit of a monster all in one file! 2 Questions: 1) If I tidy up code will you accept the adding of this additional tab to the master version? 2) What tidying up do I need to do? Other thing was that in V7 you can import private keys from the GUI via the debug console. I have started updating wiki at: https://en.bitcoin.it/wiki/How_to_import_private_keys_v7%2B(I need to add screenshots etc..) but are there any security issues about importing keys this way? Seems much more user friendly than the previous ways.

I saw on github you are still making changes. I will consider adding your tab. Could you also merge with the newest version v1.7 ? I'd like to give this Vanity Address thing a try... do you have a link that would guide me through the process? Who do I contact to find the vanity address?

I'd like to give this Vanity Address thing a try... do you have a link that would guide me through the process? Who do I contact to find the vanity address? VanityGen is a program for Linux, Windows and Mac. The forum thread is here, https://bitcointalk.org/index.php?topic=25804.0Partial key support was added about 2 months ago. It allows generating addresses/keys without having access to the key. There is a few threads discussing it's use for third party services and vanity mining. Also, my thread today about using split keys for paper wallets across two systems, here, https://bitcointalk.org/index.php?topic=114074.0I'd love to see nibor's, or some version, supported that allows printing paper wallets using split keys. In my thread I do have a post showing how this could be done step by step using vanitygen and keyconv (that comes with vanitygen). The vanity aspect of this isn't required. Using a search prefix of "1" will generate a fully random address. BTW Just looked at the new art paper wallet. Look's awesome. Very nice! Thanks. So sad my printer is junk and won't make any of this look good. edit: it worked fine with default 2 addresses per page but when I tried 3 per page, 6 total it did some funky stuff. I ended up with garbled display but the print preview looked good - except still 2 per page with the third one on a second page, and 2 sets of 2 pages. So I guess it rolled the third on to a second page as it wouldn't fit. I'm using FF 15.0.1 on Ununtu 11.04. I also have default paper set at A4. I'd like to be able to fit 3 per page but seems predefined wide margins make that impossible. Looks great otherwise.

I can verify that the BitAddress.org website has been updated and returns the same HTML from the latest commit (804d08cec0ee2e217515abe8eb762b99129003ca) in github: - https://github.com/pointbiz/bitaddress.orgTo confirm this I first check the sha1sum hash of the html returned by a request to http://bitaddress.org: $ wget --quiet -O - http://bitaddress.org|sha1sum 46215e8a2f026b784f29ea86c00c866e634a22fa - Then from my bitaddress.org repo: $ git pull $ git rev-list --max-count=1 HEAD 804d08cec0ee2e217515abe8eb762b99129003ca $ sha1sum bitaddress.org.html 46215e8a2f026b784f29ea86c00c866e634a22fa bitaddress.org.html

Awesome job!
I have one minor request: can the Art be the default, and the checkbox be "Hide Art"?
Also, the Ubuntu font didn't come through on the PNG. (The font dependency can be removed by converting the text to "outlines", essentially shapes, before doing the conversion... in Illustrator it's just right click and "convert to outlines"... not sure what it is in other tools).
If you can fix these two things and publish them at the bitaddress.org URL (at /, rather than /something), a 10 BTC silver round with free shipping is awaiting you! (your choice, plated or non.) I will PM you a code and a link.

Yes I can default the Art. I don't have Illustrator or Photoshop. I will try to grab the SVG from your file for the text you have already converted. I assumed it was using Ubuntu because on my system it was using a different font. I have printed a sheet with two notes. Each note is rather large and won't fit nicely into physical wallets. Should we maybe make it less pixels high and less pixels wide?

Yes definitely smaller if you think it's too big- I haven't printed any to test but even my own program generates big notes.
Ubuntu font is a free download, give it a google.
