Title: [ANN] bitaddress.org printing of existing backups
Post by: ErebusBat on August 31, 2012, 07:30:39 PM
Whilst getting all my ducks in a row with wallet backups I could not find an easy way to backup WIF/SIPA keys with QR codes. Blockchain.info provides a paper backup, but they are not WIF and therefore will not import into armory (and I am assuming other apps).

My workflow, to give others an idea of how to use this:
  • Create a paper wallet backup in armory, this is my deterministic armory wallet
  • Create/maintain a blockchain.info wallet with keys that are imported into my armory wallet
  • Export the bci wallet unencrypted in Sipa Wallet Format JSON
  • Paste that JSON into my new External Backup option
  • ???
  • Profit!?

You can access the code from my GitHub repository.   Be aware that this will not currently work offline as it loads the CoffeeScript runtime.  If there is sufficient need/interest I can change this.

Added VanityGen format as an available (and very generic format) that will print as well.  This should provide a way to create paper backups for most any existing address lists.

Can you point it to a wallet.dat file and have it print all the private keys from it?

No, because it is just a webpage... however I can probably add the bitcoind JSON response to it pretty easy.

Hrm... looks like my version of bitcoind doesn't have the dumpwallet command in it... I will need to look at my linux machine.
