# encryptionProvider=providerName attribute

#### Function

Specifies the provider for data encryption. For information about data encryption, see "Encrypting databases on disk" in the Java DB Developer's Guide.

If this attribute is not specified, the default encryption provider is the one included in the JVM that you are using.

#### Combining with other attributes

The encryptionProvider attribute must be combined with the bootPassword=key and dataEncryption=true attributes. You can also specify the encryptionAlgorithm=algorithm attribute.

For an existing, unencrypted database for which authentication and SQL authorization are both enabled, only the database owner can perform encryption or reencryption. Please see "Enabling user authentication" and "Setting the SQL standard authorization mode" in the Java DB Developer's Guide for more information.

#### Examples

    -- create a new, encrypted 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
