    We store encrypted data in the database, the key on the file system,
    and the specific configuration of the key in the java code (parameters
    to the key).

    This requires someone gain access to all three parts in order to
    decrypt the data. We manage the encryption in the application as
    this allows us to only have the decrypted values in memory for as
    short a period of time as necessary.
