CREATE MASTER KEY SYSTEM PASSWORD
CREATE MASTER KEY ENCRYPTION BY PASSWORD = '' Use the following example to create a database master key in a database. Requires CONTROL permission on the database. The service master key and database master keys are protected by using the AES-256 algorithm. Therefore, the master key password is optional in SQL Database and Azure Synapse Analytics. In order to recover the master key, and all the data encrypted using the master key as the root in the key hierarchy after the database has been moved, the user will have either use OPEN MASTER KEY statement using one of the passwords used to protect the master key, restore a backup of the master key, or restore a backup of the original service master key on the new server.įor SQL Database and Azure Synapse Analytics, the password protection is not considered to be a safety mechanism to prevent a data loss scenario in situations where the database may be moved from one server to another, as the service master key protection on the master key is managed by Microsoft Azure platform. In case of the database being physically moved to a different server (log shipping, restoring backup, etc.), the database will contain a copy of the master key encrypted by the original server service master key (unless this encryption was explicitly removed using ALTER MASTER KEY DDL), and a copy of it encrypted by each password specified during either CREATE MASTER KEY or subsequent ALTER MASTER KEY DDL operations. Information about the database master key is visible in the sys.symmetric_keys catalog view.įor SQL Server and Parallel Data Warehouse, the master key is typically protected by the service master key and at least one password. The is_master_key_encrypted_by_server column of the sys.databases catalog view in master indicates whether the database master key is encrypted by the service master key. The Concepts and Mechanics of Master Keying: Developing Master Keys Using Generic Types. A master key that is not encrypted by the service master key must be opened by using the OPEN MASTER KEY statement and a password. This default can be changed by using the DROP ENCRYPTION BY SERVICE MASTER KEY option of ALTER MASTER KEY. Typically, the copy stored in master is silently updated whenever the master key is changed. To enable the automatic decryption of the master key, a copy of the key is encrypted by using the service master key and stored in both the database and in master. In SQL Server 2008 (10.0.x) and SQL Server 2008 R2 (10.50.x), the Triple DES algorithm is used. When it is created, the master key is encrypted by using the AES_256 algorithm and a user-supplied password. The database master key is a symmetric key used to protect the private keys of certificates and asymmetric keys that are present in the database. password is optional in SQL Database and Azure Synapse Analytics.
CREATE MASTER KEY SYSTEM WINDOWS
password must meet the Windows password policy requirements of the computer that is running the instance of SQL Server. The password that is used to encrypt the master key in the database. Master keying is the process of creating a hierarchical structure of keys that allows authorized individuals to access specific locks while granting a single. The master key login for every account requires in addition to the entry of the master key, the additional entry of the 2-factor code.To view Transact-SQL syntax for SQL Server 2014 and earlier, see Previous versions documentation. After providing the Bio-ITech with the generated SHA-256 hash of the chosen master key, Bio-ITech will provide the System Administrator with a security token to set-up 2-factor authentication (compatible with Google Authenticator, WithAuth or Protectimus Slim mini ). For security reasons, the master key login is protected with a mandatory 2-step verification. The generated SHA-256 key should be provided to Bio-ITech to be installed on the eLabInventory Private Cloud or On-Premise system installation.
The SHA-256 is generated with a system-specific salt. Open Generate MasterKey.Ĭhoose a strong password and enter in the password field and click Generate SHA-256 to generate the SHA-256 hash of the master password. To generate a master key that provides access to all user accounts in the system, navigate to the System Admin panel and open the System Settings tab.
