Encrypting databases with a new boot password

You can apply a new boot password to a Derby database by specifying the newBootPassword attribute on the connection URL when you boot the database.

When you use the newBootPassword attribute, a new encryption key is generated internally by the engine and the key is protected using the new boot password. The newly generated encryption key encrypts the database, including the existing data. You cannot change the encryption provider or encryption algorithm when you apply a new boot password.

To encrypt a database with a new boot password:

Specify the newBootPassword attribute in a URL and reboot the database. For example, when the following URL is used when the salesdb database is rebooted, the database is encrypted with the new encryption key, and is protected by the password new1234xyz:
 jdbc:derby:salesdb;bootPassword=abc1234xyz;newBootPassword=new1234xyz
If you disabled log archival before you applied the new boot password, create a new backup of the database after the database is reconfigured with new the boot password.
