Actian Vector offers a full suite of security features, all of which are described in the Actian Vector Security Guide. In particular, Vector provides encryption capability, including data-at-rest encryption and communications encryption.

The data-at-rest encryption is AES encryption where keys are derived from a user-specified passphrase. The key is generated randomly at table creation time and is encrypted with the passphrase. The encrypted key is stored in a system table named "iirelation". Without the passphrase, you cannot retrieve the decrypted key. If you change the passphrase, you change the way the key is encrypted, but you do not actually change the key. Passphrases can be modified with an SQL MODIFY statement.
