When executed without the FROM clause, CREATE ASYMMETRIC KEY generates a new key pair. In its default form, this entity contains both a public key and a private key. RemarksĪn asymmetric key is a securable entity at the database level.
2048 TITLE PASSWORD
password must meet the Windows password policy requirements of the computer that is running the instance of SQL Server. If this clause is not present, the private key will be encrypted with the database master key. Specifies the password with which to encrypt the private key. If CREATION_DISPOSITION = OPEN_EXISTING is not provided, the default is CREATE_NEW. PROVIDER_KEY_NAME must be used to specify key name on the device. Maps a SQL Server asymmetric key to an existing Extensible Key Management key. If a key already exists on the device the statement fails with error. Specifies the key name from the external provider.Ĭreates a new key on the Extensible Key Management device. PROVIDER_KEY_NAME = ' key_name_in_provider' To use RSA_1024 or RSA_512 (not recommended) you must set the database to database compatibility level 120 or lower. For more information about external key management, see Extensible Key Management (EKM).įive algorithms can be provided RSA_4096, RSA_3072, RSA_2048, RSA_1024, and RSA_512. The provider must be defined first using the CREATE PROVIDER statement. Specifies the name of an Extensible Key Management (EKM) provider. Specifies the name of a signed assembly that has already been loaded into the database from which to load the public key. This option is not available in a contained database.
