Since transaction history is stored unencrypted in wallet.dat on disk, this isn't much of a problem but senttxstore.dat actually stores some data that is never stored in wallet.dat files, such as outgoing zxtn data (not including memo). It would be an improvement to allow the user to encrypt metadata stored on disk by SD, something similar to the SDA PIN idea.
