To create an encrypted database You can use the following:
The Initialization utility (dbinit) in combination with various options to enable strong encryption.
The dbinit utility -ep and -ek options create a database with strong encryption, allowing you to specify the encryption key in a prompt box or on the command line. The dbinit -ea option sets the encryption algorithm to AES or AES256 (or to AES_FIPS or AES256_FIPS for the FIPS-certified module).
CREATE DATABASE statement.
The Sybase Central Create Database Wizard to create a strongly encrypted database.
To encrypt an existing database Although you cannot simply turn strong encryption on or off in an existing database, you can use one of the following to implement strong encryption:
Rebuild (unload/reload) an existing database and change the encryption status at that time. You can rebuild the database to unload all the data and schema of an existing database. This creates a new database (at which point you can change a variety of settings including strong encryption status), and reloads the data into the new database. You need to know the key to unload a strongly encrypted database. To rebuild (unload/reload) a database, use one of the following methods:
The Unload utility (dbunload)
The Unload utility (dbunload) with options to create a new database with strong encryption. The -an option creates a new database. To specify strong encryption and the encryption key in a prompt box or on the command line use the -ep or -ek option. The -ea option sets the encryption algorithm to AES or AES256 (or to AES_FIPS or AES256_FIPS for the FIPS-certified module).
The UNLOAD and RELOAD statements
The Unload Database Wizard. See Tips on exporting data with the Unload Database Wizard.
You can use the CREATE ENCRYPTED DATABASE statement or the CREATE ENCRYPTED FILE statement. See Comparison of CREATE ENCRYPTED DATABASE and CREATE ENCRYPTED FILE statements.
To encrypt tables, columns, and materialized views See Column and table encryption.
