encryptionAlgorithm=algorithm attribute The encryptionAlgorithm=algorithm attribute specifies the algorithm for data encryption. encryptionAlgorithm=algorithm database connection URL attribute encrypting databasesencryption algorithms databasesencryption attributes attributesencryptionAlgorithm

Use the Java conventions when you specify the algorithm. For example:

algorithmName/feedbackMode/padding

The only padding type that is allowed with is NoPadding.

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

For information about data encryption, see "Configuring database encryption" in the .

Combining with other attributes

The encryptionAlgorithm=algorithm attribute must be combined with the dataEncryption=true attribute and with either the bootPassword=key attribute or the encryptionKey=key attribute. You can also use the encryptionProvider=providerName attribute to specify the encryption provider of the algorithm.

For an existing database for which authentication and SQL authorization are both enabled, only the database owner can perform encryption or reencryption. See "Configuring user authentication" and "Configuring user authorization" in the for more information.

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