[ANN] bitaddress.org Safe JavaScript Bitcoin address/private key

[Dacm4n]

Nevermind I fixed the problem. (ignore this message.)

[phelix]

May I suggest the following improvements:

1. Compressed keys for all output of paper wallet and bulk wallet, as an option. (Might as well include all other wallets, single wallets, brain wallets, vanity, etc.)
2. Choose a level of error correction for the QR codes. I prefer High or 30%. What is the level right now for version 2.4 ?

1. Yeah, that would be nice. Not sure how well compressed private keys are supported yet, though.

edit: please note that this will not make the private key or the address any shorter. It will only make the public key shorter and thus save space on the blockchain.

2. It is high for both codes (as it just generated).

v2.4

I'm a little late on verifying 2.4, but here it is:

I can verify that the BitAddress.org website has been updated and returns the same HTML from the commit with the description v2.4 (1d5951f6a04dd5a287ac925da4e626870ee58d60) in github:
 - https://github.com/pointbiz/bitaddress.org


To 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
1d5951f6a04dd5a287ac925da4e626870ee58d60  -

$ GET -eSd bitaddress.org|grep -i "200 OK"
GET https://www.bitaddress.org/bitaddress.org-v2.4-SHA1-1d5951f6a04dd5a287ac925da4e626870ee58d60.html --> 200 OK


Then from my bitaddress.org repo:

$ git checkout master
$ git pull
$ git log --pretty=oneline|grep "v2.4"
eeed4db91edd9eda5eb4277a61aa16ad80bdcdcb v2.4 French translations

$ git checkout eeed4db91edd9eda5eb4277a61aa16ad80bdcdcb
$ git rev-list --max-count=1 HEAD
eeed4db91edd9eda5eb4277a61aa16ad80bdcdcb

$ sha1sum bitaddress.org.html
1d5951f6a04dd5a287ac925da4e626870ee58d60  bitaddress.org.html

Hi

I have a question or three.

1. If i generate an address offline by going to the page, disconnecting wifi and generating a new address is this address now good to go?

2. How do i check the balance on the address?

3. How do i move the balance from there to another address?

Thanks

1. If i generate an address offline by going to the page, disconnecting wifi and generating a new address is this address now good to go?

Depending on whether or not your system is compromised.   Let's say you have malware that does a screen shot a couple times each second and uploads next time you reconnect the images of QR codes it snagged?

[Update: The solution is to use a LiveOS, i.e., boot to an operating system you know was not tampered with.   Then while offline load the static .html page that was originally obtained from bitaddress.org and verified using the sha1sum to be the same release as from github or from the site.]

2. How do i check the balance on the address?

Blockchain.info will show transactions where that address was used.

3. How do i move the balance from there to another address?

You need to import the private key somewhere.  

Bitcoin-Qt from the debug console has a way to import private key.
 - http://en.bitcoin.it/wiki/How_to_import_private_keys

Blockchain.info/wallet provides an import private key method.

Using a mobile, EasyWallet.org has "one touch" scanning to do this.

Also Mt. Gox has the ability to redeem a private key in which they sweep the funds into your Mt. Gox exchange account.

I recommend using tails. Burn to CD or put on USB stick, restart your computer and boot it to tails (while offline), once finished it will remove all traces.

Hi, is it possible to generate a paper wallet safely with 2 compromised computers using the vanity key generator?
I've been wondering this for a long time.

Yes, I've done it. See my post here:
https://bitcointalk.org/index.php?topic=43496.msg1421075#msg1421075

Here is another break down of the steps:
https://en.bitcoin.it/wiki/Two-factor_paper_wallet

I want to make this process more user friendly to do in bulk. To manually make 10 wallets using the steps I described is tedious but very secure!

A similar process may be possible using BIP38 encrypted wallets in the future. I'm still adding BIP38 support to the codebase.

Hi All,


I used the bitaddress.org source code to make a Dr. Evil paper wallet generator that is located here:

http://evilwallet.wordpress.com/


You can see the difference between my code and the bitaddress.org source code from their github repo by using a online utility such as: http://www.comparemyfiles.com/ to compare the two files and see for yourself quite quickly.

My source code: https://github.com/obesityspray/Dr.-Evil-Paper-Wallet

Bitaddress.org github repo: https://github.com/pointbiz/bitaddress.org


Newbie Thread discussing this generator: https://bitcointalk.org/index.php?topic=186007.0

I hope you enjoy!

If anybody is interested or concerned about what kind of paper to print these on, I have done some quick research and ended up ordering this:

Wallet Verification.

I have a script here to verify online wallets. https://github.com/carbonwallet/walletverification

Basically the script downloads the wallet via the URL and then via cloning the repo and does a diff.

It's currently setup to work with carbonwallet but should be easy to add bitaddress.

In the end what I would like to see is a number of volunteers running the script via cron with perhaps a small PHP page that shows the output. Then we would have various places to check the integrity of all these repo based wallets.

Let me know what you think.

[virtualmaster]

What about a namecoin implementation of bitaddress.org ?
It would be very useful.

[OpenYourEyes]

My SHA1 sums from the Git repo don't match what in the version history.
Any one else getting this?

Edit: NVM.

Dear developers and coders,

I would like to suggest an idea:

Wouldn't it be nice if we had an option to generate and broadcast a transaction to Bitcoin network in a way as similiar as the one available at http://brainwallet.org/#tx ?

It might, but why not just use that one?  It needs a webservice to broadcast the transaction for it since there's no (widely-supported) way for a Javascript page to do low-level socket stuff necessary to get on the Bitcoin p2p network.  So, you could add a feature to bitaddress.org to broadcast a transaction through blockchain.info/pushtx if you want, but I don't see the point of duplicating that and making bitaddress.org more complex.

Hi,

I'm waiting for the bulk generation of compressed public keys. The page already has this capability in the Wallet Details Tab.

Try the patch I just wrote.  It's a pretty straightforward change, especially since compressed support is nicely integrated into the core code.  You can download the html here.

Hey,

this guy http://www.davidduckwitz.de got a 1:1 copy of your script and writes down that his script is by "danielduckwitz"

Is that okay for you that other people use your code and claim that is theirs? He also sells is on the website for 18 euro



How is your copyright? Are you fine with that or not?

If you are not fine with that than you might write in this posting

https://bitcointalk.org/index.php?topic=200820.0

Copy his name and address and reply it in his thread. so his theft is written down there forever.


BTW: He changed the donation address to his own wallet. We should bust this moth********

He broke multiple laws in germany with that. "urheberrecht". And he SOLD you script for 18 EUR. Maybe you should  accept a donation of 10k€ in order to get his public address deleted in the forums... You have the right to do that.

i'd be more concerned if it wasn't a 1:1 copy
