encryptionAlgorithm=algorithm

Function

Specifies the algorithm for data encryption.

Use the Java conventions when you specify the algorithm, for example:

algorithmName/feedbackMode/padding

The only padding type that is allowed with Derby is NoPadding.

If no encryption algorithm is specified, the default value is DES/CBC/NoPadding.

For information about data encryption, see "Encrypting Databases on Disk" in the Derby Developer's Guide.

Combining with other attributes

The encryptionAlgorithm attribute must be combined with the bootPassword=key attribute and the dataEncryption=true attribute. You have the option of also specifying the encryptionProvider=providerName attribute to specify the encryption provider of the algorithm.

Examples

 -- encrypt a new database
    jdbc:derby:encryptedDB;create=true;dataEncryption=true;
    encryptionProvider=com.sun.crypto.provider.SunJCE;
    encryptionAlgorithm=DESede/CBC/NoPadding;
    bootPassword=cLo4u922sc23aPe
-- configure an existing database for encryption 
    jdbc:derby:salesdb;dataEncryption=true; 
    encryptionProvider=com.sun.crypto.provider.SunJCE; 
    encryptionAlgorithm=DESede/CBC/NoPadding; 
    bootPassword=cLo4u922sc23aPe

Note: If the specified provider does not support the specified algorithm, Derby returns an exception.
