Remarks

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

To set any AsymmetricKey object properties and run the Alter method, users must have CONTROL permission on the database.

To create an AsymmetricKey object, users must have CREATE ASYMMETRIC KEY role permission on the parent database.

To drop an AsymmetricKey object, users must be the owner of the asymmetric key or have CONTROL permission on the asymmetric key.

To grant, deny, and revoke permission on the AsymmetricKey object, users must have CONROL permission on the asymmetric key.

Examples

Granting, Revoking, and Denying Permissions

Thread Safety

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
