ASYMKEYPROPERTY (Key_ID , 'algorithm_desc' | 'string_sid' | 'sid')
Key_ID
The Key_ID of an asymmetric key in the database. If you only know the key name, use ASYMKEY_ID to find the Key_ID. Key_ID has data type int.
'algorithm_desc'
Specifies that the output returns the algorithm description of the asymmetric key. Only available for asymmetric keys created from an EKM module.
'string_sid'
Specifies that the output returns the SID of the asymmetric key, in nvarchar() format.
'sid'
Specifies that the output returns the SID of the asymmetric key in binary format.
sql_variant
Requires appropriate permission(s) on the asymmetric key, and requires that the caller has not been denied VIEW permission on the asymmetric key. See CREATE ASYMMETRIC KEY (Transact-SQL) for more information about asymmetric key permissions.
The following example returns the properties of the asymmetric key of Key_ID 256.
SELECT
ASYMKEYPROPERTY(256, 'algorithm_desc') AS Algorithm,
ASYMKEYPROPERTY(256, 'string_sid') AS String_SID,
ASYMKEYPROPERTY(256, 'sid') AS SID ;
