Asymmetric Keys
An asymmetric key is a securable entity on the database level. Asymmetric encryption requires a pair of keys: one public, the other private. You can create an asymmetric key entity from a key or pair of keys retrieved from a file or assembly.
Note: The object is available only for Microsoft SQL server 2005.
Creating Asymmetric Keys
New asymmetric keys are created within Create Asymmetric Key Wizard. In order to run the wizard you should either
| • | select the Object | Create Database Object... main menu item; |
| • | select the Asymmetric Key icon in the Create Database Object dialog |
or
| • | select the Asymmetric Keys list or any object from that list in the explorer tree; |
| • | select the Create New Asymmetric Key... item from the popup menu |
or
| • | open the database in Database Editor and the Asymmetric Keys tab there; |
| • | press the Insert key or select the Create New Asymmetric Key... item from the popup menu (alternatively, you may use the corresponding link of the Navigation Bar). |
To create a new asymmetric key with the same properties as one of the existing asymmetric keys has:
| • | select the Object | Duplicate Database Object... main menu item; |
| • | follow the instructions of Duplicate Object Wizard. |

Dropping Asymmetric Keys
