The only way to change the type of database encryption is to recreate the database with the appropriate fips or obfuscate
creation parameter. You can change the database encryption key by specifying a new encryption key on the Connection object.
Users connecting to the database must supply the key each time they connect.
From Sybase Central, you can configure strong encryption in any wizard that creates a database. On the New Database Storage Settings page, select the AES FIPS Algorithm option. You must also set and confirm the encryption key.
Set this parameter as one of the creation parameters for the create database method on the database manager class.
