Encrypting A Database

Encrypting a Database

Encrypts the database using the specified encryption plugin

Syntax

ALTER {DATABASE | SCHEMA}
  ENCRYPT WITH plugin_name [KEY key_name]

Table 1. `ALTER DATABASE ENCRYPT` Statement Parameters
Parameter	Description
plugin_name	The name of the encryption plugin
key_name	The name of the encryption key

Encryption starts immediately after this statement completes, and will be performed in the background.Normal operations of the database are not disturbed during encryption.

The optional KEY clause specifies the name of the key for the encryption plugin.The plugin decides what to do with this key name.

Note

The encryption process can be monitored using the MON$CRYPT_PAGE field in the MON$DATABASE virtual table, or viewed in the database header page using gstat -e.gstat -h will also provide limited information about the encryption status.

For example, the following query will display the progress of the encryption process as a percentage.

select MON$CRYPT_PAGE * 100 / MON$PAGES
  from MON$DATABASE;

Note	`SCHEMA` is currently a synonym for `DATABASE`;this may change in a future version, so we recommend to always use `DATABASE`
