Are there any opensource, simple tools that can be used just to generate paper wallet addresses? I know there are some BTC wallet clients that do this, I believe, and some websites with client side tools that can be used offline, but I was hoping for something dirt simple that may also offer some ability to make sure its been peer reviewed and that the client I download is the same via checksum or something. Like an entirely downloadable version of Bitaddress.org.

Start a secure browser session.  Go to - https://www.bitaddress.org - disconnect from the internet.  Reload page then print off as many copies as you need.

Go to bitaddress.org - right click - view source - save it into a local .html file - go offline - run it.

The entire site is a single file with no references or dependencies.  Even the images are base64-encoded to maintain it as a single file.

Companies claiming they got hacked and lost your coins sounds like fraud so perfect it could be called fashionable.  I never believe them.  If I ever experience the misfortune of a real intrusion, I declare I have been honest about the way I have managed the keys in Casascius Coins.  I maintain no ability to recover or reproduce the keys, not even under limitless duress or total intrusion.  Remember that trusting strangers with your coins without any recourse is, as a matter of principle, not a best practice.  Don't keep coins online. Use paper wallets instead.

Ideally you would securely transfer a save of the page (which you saved on a secure computer, of course Wink ) to your offline savings wallet computer / OS.

You can then even use another computer to redownload and compare using a hash, to ensure that you haven't gotten a targeted malicious copy, however unlikely that may be.

edit: bad link

Or compare to the signed SHA1 hash given by its author - the link to the signed message is in the page itself at the bottom.
