Requirements for Derby Encryption

Requirements for Derby Encryption

Derby supports disk encryption, but you must supply the following:

  • An implementation of the Java Cryptographic Extension (JCE) package version 1.2.1 or higher.

    Derby does not support earlier, non-exportable, versions of JCE (such as JCE 1.2). More information on JCE 1.2.1, including a product download, can be found at: http://java.sun.com/products/jce/index.html.

    Any attempt to create or access an encrypted database without the libraries for an implementation of JCE of the proper version, or without Java(TM) 2 Platform, Standard Edition, v 1.2 (J2SE) or higher, raises an exception; you will not be able to create or boot the database.

    The JCE installation documentation describes configuring (registering) the JCE software. You do not need to do this; Derby registers JCE dynamically.
  • the encryption provider

    An encryption provider implements the Java cryptography concepts. The JRE for J2SE 1.4 or J2EE 1.4 includes JCE and one or more default encryption providers.
