주의

A database master key is used to symmetrically encrypt keys and certificates that are stored in the database. A database master key can be encrypted by using the service master key or by using a user-specified password. When a database master key is created, a password must be supplied to encrypt and decrypt it.

When a database is attached to an instance of SQL Server, the database administrator must either supply the master key password or make an unencrypted copy of the master key that is available for encryption with the service master key.

The service master key is the top layer in the encryption hierarchy that is used to encrypt lower layers in the encryption hierarchy. The service master key is generated automatically by Windows. It can be opened only by the Windows service account under which it was created, or by a user who knows both the service account name and its password.

To get MasterKey object properties, users can be a member of the public fixed server role.

To set MasterKey object properties, users must have CONTROL permission on the database or be a member of the db_owner fixed database role.

To create or drop a master key, users must have CONTROL permission on the database or be a member of the db_owner fixed database role.

To open or regenerate a master key, users must have CONTROL permission on the database or be a member of the db_owner fixed database role.

To add or drop service key encryption, users must have CONTROL permission on the database or be a member of the db_owner fixed database role.

To drop a master key, users can be a member of the public fixed server role.
