Key options
Key source
Specify a passphrase that will be used to derive the key from.
Algorithm
Use the drop-down list to specify an algorithm to be used by the symmetric key. Possible values are: DES, TRIPLE_DES, RC2, RC4, DESX, AES_128, AES_192, AES_256.
Identity value
Specify an identity phrase from which to generate a GUID for tagging data that is encrypted with a temporary key.
Create date
Stores the date when the symmetric key was created.
Modify date
Stores the date when the symmetric key was last modified.
Symmetric key encrypt by
This area lists the encrypting mechanisms used by the symmetric key (the ENCRYPTION BY clause).
To add an encrypting mechanism, right-click within the Symmetric key encrypt by area and select the Add Encryption popup menu item.
The Add Encryption By dialog allows you to specify a password, a certificate, an asymmetric key, or a symmetric key to be used to encrypt the key that is being created.
To remove an encrypting mechanism, right-click the encrypting mechanism within the Symmetric key encrypt by area and select the Drop Encryption popup menu item.
