If you create a paper wallet, follow following steps for maximum security:
- DOWNLOAD their sourcecode (at this moment, the latest version of their sourcecode can be downloaded from https://github.com/pointbiz/bitaddress.org/archive/v3.3.0.zip , But you shouldn't trust anybody that shoves a link in your face and surf to bitaddress.org yourself and find a link to the lastest version of their sourcecode)
- disconnect from the internet
- unpack the sourcecode, open the index page
- create a paper wallet (bip38 encrypted), print it on a directly attached printer... Make several copies
- Reboot the printer + PC before you even attempt to reconnect from the internet
- Laminate the paper wallet(s) and store them in multiple dry, dark, cool, physically protected places (like a banksafe)... If a fire destroys your house, you still need to have a copy of the paper wallet in order to access your funds
