[!INCLUDE[tsql-appliesto-ss2016-xxxx-asdw-xxx-md](../../includes/tsql-appliesto-ss2016-xxxx-asdw-xxx-md.md)]

  Returns information about column encryption keys (CEKs) created with the [CREATE COLUMN ENCRYPTION KEY](../../t-sql/statements/create-column-encryption-key-transact-sql.md) statement. Each row represents a CEK.  
  
|Column name|Data type|Description|  
|-----------------|---------------|-----------------|  
|**name**|**sysname**|The name of the CMK.|  
|**column_encryption_key_id**|**int**|ID of the CEK.|  
|**create_date**|**datetime**|Date the CEK was created.|  
|**modify_date**|**datetime**|Date the CEK was last modified.|  
  
## Permissions  
 Requires the **VIEW ANY COLUMN ENCRYPTION KEY** permission.
