Topic: [ANN] bitaddress.org Safe JavaScript Bitcoin address/private key - page 46. (Read 153371 times)

Sweet, it's nearing perfect utilitarian function!

V0.3

-Removed Private Key Base64
-Added Private Key Wallet Import Format

V0.2

-Updated the logo
-Added New Address and Print buttons
-Added doctype so IE9 renders in standards mode
-Added Array.prototype.map for IE7/8 compatibility
-Known bug: Bitcoin.Base58.encode is not working properly in IE7

Many thanks! I promise I'll spend them for good and decent causes.

Thank you for the algorithm, I was going to dig it from some C# code you posted and port.

Looks like it defaults to quirks mode in IE9, I'll fix that in V0.2 as well as add the WIF.

Excellent achievement.  Somebody needed to do this.  It wouldn't run in IE9 btw but runs fine in other browsers.

Instead of base64 you should provide the Wallet Import Format, which is how it is used on Bitbills and the format natively used by the "importprivkey" command of bitcoind (available by sipa's patch, and will likely become part of the release).

Wallet Import Format is: you construct it exactly the same as a bitcoin address in base58, but use the header byte 0x80 at the beginning instead of 0x01.  And of course your payload is 32 bytes instead of 20.  You do the SHA256 checksum exactly the same way.  The resulting string should always start with the character '5'.

Also a suggestion: recommend that the user disconnect themselves from the internet, print their "paper wallet", and close their browser before reconnecting.  That way they can confirm they're airgapped.  You'd need a button to generate a new address instead of having them refresh in this case.

nmat, thanks.

Bookmarked it. Thank you very much I claimed the bounty, but I will offer half of it (0.05) here:

Please post if you collect the bounty. Thanks.

UPDATED!

Generate a Bitcoin address and corresponding private key with this all-in-one html page:
https://www.bitaddress.org/

Testnet Edition (for developers) add ?testnet=true to the end of the URL

To run the unit tests add ?unittests=true to the end of the URL
To run the async unit tests add ?asyncunittests=true to the end of the URL
To view the seed pool add ?showseedpool=true to the end of the URL

NOTICE: DO NOT USE v0.1 to v0.4 they infrequently generate a bad address and/or private key. The issue is fixed in v0.5+
NOTICE: DO NOT USE v2.1 on the Vanity Wallet tab it incorrectly multiplies a public key with a private key and therefore displays an incorrect bitcoin address. The issue is fixed in v2.2+
NOTICE: DO NOT USE v2.9.7 translations file has a JavaScript error.

Tutorial:
Open the page, move your mouse around a bit and you will get a new address/private key combination.

Useful for:
1) The HTML file can be saved to disk and used in combination with an "offline" system to provide super security.
2) Generate an instant paper wallet by just printing the web page.
3) Generate address without having to install anything!

Please share any other uses you can think of....

Verifying the release:
1) get public key of author
2) import public key of author
3) get HTML from bitaddress.org
4) sha1 checksum of HTML
5) verify signed message from author
6) confirm sha1 in step 4 & 5 matches
NOTE: If the web page is saved as "web page complete" as opposed to "web page html only" the checksum will not match.
