Can't withdraw from paper wallets w/o MtGox??

[velcrovan]

Was looking into creating a paper wallet, but when I read this on the wiki it concerned me:

The Bitcoin software does not yet have a built-in way to load private keys, but you can use the "Add Funds" - "Private key" screen at MtGox to recover digital coins from a private key. (source)

So, if I transfer bitcoins to a "paper wallet" (basically a bitcoin address which has no actual wallet.dat file and the private key exists only on paper, right?) then I need MtGox to get those coins back out again some day??

What if MtGox goes down?

There is an "importprivkey" command included in the official Bitcoin client if you pass it over JSON-RPC.

Worst case someone has to re-implement it. It's some series of SHA iterations, not really catastrophic to write. A few people probably already have scripts for it, Casascius might know something.

Edit: or what mcorlett said. Don't know whether this supports the mini-key format though.

The paper wallet is just a paper backup of your wallet.dat file.

If you have a HD crash and lose your bitcoin client install you can just re-install bitcoin and import the data from the backup.

They say the paper wallet is the safest but I guess it's just preference.  I store multiple encrypted copies of the wallet.dat file around the internet and on a USB drive.

Blockchain.info/wallet has excellent import and export facilities.

I think I'm looking at a paper wallet as a hedge against hacking just as much as protection from HD crashes. I.e., a separate savings wallet.
