Encrypting databases with a new boot password

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

When you use the newBootPassword=newPassword 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=newPassword attribute in a URL and reboot the database. For example, if you use the following URL to reboot the salesdb database, the database is encrypted with the new encryption key and is protected by the password new1234xyz:

If authentication and SQL authorization are both enabled, the credentials of the database owner must be supplied as well, since reencryption is a restricted operation.

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 the new boot password. For more information, see the section "Backing up and restoring databases" in the Java DB Server and Administration Guide, particularly "Roll-forward recovery".
