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
|
||||
passphrase 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 your 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.
|
||||
|
||||
|
||||
Technical details of wallet encryption
|
||||
--------------------------------------
|
||||
Wallet encryption uses AES-256-CBC to encrypt only the private keys
|
||||
that are held in a wallet. The keys are encrypted with a master key
|
||||
which is entirely random. This master key is then encrypted with
|
||||
AES-256-CBC with a key derived from the passphrase using SHA512 and
|
||||
OpenSSL's EVP_BytesToKey and a dynamic number of rounds determined by
|
||||
the speed of the machine which does the initial encryption (and is
|
||||
updated based on the speed of a computer which does a subsequent
|
||||
passphrase change). Although the underlying code supports multiple
|
||||
encrypted copies of the same master key (and thus multiple passphrases)
|
||||
the client does not yet have a method to add additional passphrases.
|
||||
|
||||
At runtime, the client loads the wallet as it normally would, however
|
||||
the keystore stores the keys in encrypted form. When the passphrase
|
||||
is required (to top up keypool or send coins) it will either be queried
|
||||
by a GUI prompt, or must first be entered with the walletpassphrase
|
||||
RPC command. This will change the wallet to "unlocked" state where the
|
||||
unencrypted master key is stored in memory (in the case of GUI, only for
|
||||
long enough to complete the requested operation, in RPC, for as long as
|
||||
is specified by the second parameter to walletpassphrase). The wallet is
|
||||
then locked (or can be manually locked using the walletlock RPC command)
|
||||
and the unencrypted master key is removed from memory.
|
||||
|
||||
Implementation details of wallet encryption
|
||||
-------------------------------------------
|
||||
When the wallet is locked, calls to sendtoaddress, sendfrom, sendmany,
|
||||
and keypoolrefill will return Error -13: "Error: Please enter the wallet
|
||||
passphrase with walletpassphrase first."
|
||||
|
||||
When the wallet is unlocked, calls to walletpassphrase will fail.
|
||||
|
||||
When a wallet is encrypted, the passphrase is required to top up the
|
||||
keypool, thus, if the passphrase is rarely entered, it is possible that
|
||||
keypool might run out. In this case, the default key will be used as the
|
||||
target for payouts for mining, and calls to getnewaddress and getaccount
|
||||
address will return an error. In order to prevent such cases, the keypool
|
||||
is automatically refilled when walletpassphrase is called with a correct
|
||||
passphrase and when topupkeypool is called (while the wallet is unlocked).
|
||||
Note that the keypool continues to be topped up on various occasions when
|
||||
a new key from pool is used and the wallet is unlocked (or unencrypted).
