nnyld, ScaryKubiak, pluh, r3wt (and others) -
I have said before that although we have done literally everything we can think of to make our site as absolutely secure as possible, we know that there is always a possibility of any site being hacked...even the White House's site has been hacked in the past.
The Paper Vaults that The Bank of Bitcoin allows its Members to create CANNOT be hacked. They are literally just as secure as any paper wallet. I have stated this so many times, in so many ways, that I am reminded of the scene in "The Shawshank Redemption" where the lead character called the warden "obtuse" for seeming to deliberately misunderstand what he was being told.
Even if our site were hacked, any Bitcoins in your Paper Vault would be absolutely safe. This is quite unique for an online Bitcoin Service: when other online services are hacked your Private Keys and Bitcoins are gone; with us, it would be an inconvenience, but the Bitcoins and Private Keys in your Paper Vaults would remain safe.
Furthermore, to combat the possibility of the injection of malicious code into the client-side javascript used to manipulate your Paper Vaults we have described a two- or three-minute method to check that our code has not been altered (either by a hacker or otherwise).
It should be obvious that we take security VERY seriously, and have created an online Bitcoin service which handles that security by putting YOUR Private Keys and YOUR Bitcoins in YOUR hands, and yet STILL allowing you to send your Bitcoins from any javascript-enabled Internet-connected device. This is a very unique, valuable and secure service - and I am proud of what we have accomplished.
