 Wallet Encryption
 -----------------
-Bitcoin supports native wallet encryption so that people who steal your wallet
-file don't automatically get access to all of your Bitcoins.  In order to enable
-this feature, chose "Encrypt Wallet" from the Options menu.  You will be prompted
-to enter a passphrase, which will be used as the key to encrypt your wallet and
-will be needed every time you wish to send Bitcoins.  If you lose this passphrase,
-you will lose access to spend all of the bitcoins in your wallet, no one, not even
-the Bitcoin developers can recover your Bitcoins.  This means you are responsible
-for your own security, store your password in a secure location and do not forget
-it.

-Remember that the encryption built into bitcoin only encrypts the actual keys
-which are required to send your bitcoins, not the full wallet.  This means that
-someone who steals your wallet file will be able to see all the addresses which
-belong to you, as well as the relevant transactions, you are only protected from
-someone spending your coins.

-It is recommended that you backup your wallet file before you encrypt your wallet.
-To do this, close the Bitcoin client and copy the wallet.dat file from ~/.bitcoin/
-on Linux, /Users/(user name)/Application Support/Bitcoin/ on Mac OSX, and
-%APPDATA%/Bitcoin/ on Windows (that is /Users/(user name)/AppData/Roaming/Bitcoin on
-Windows Vista and 7 and /Documents and Settings/(user name)/Application Data/Bitcoin
-on Windows XP).  Once you have copied that file to a safe location, reopen the
-Bitcoin client and Encrypt your wallet.  If everything goes fine, delete the backup
-and enjoy your encrypted wallet.  Note that once you encrypt your wallet, you will
-never be able to go back to a version of the Bitcoin client older than 0.4.

-Keep in mind that you are always responsible for you own security.  All it takes is a
-slightly more advanced wallet-stealing trojan which installs a keylogger to steal
-your wallet passphrase as you enter it in addition to your wallet file and you have
-lost all your Bitcoins.  Wallet encryption cannot keep you safe if you do not practice
-good security, such as running up-to-date antivirus software, only entering your
-wallet passphrase in the Bitcoin client and using the same passphrase only as your
-wallet passphrase.
