# sys.column_encryption_key_values (Transact-SQL)
[!INCLUDE[tsql-appliesto-ss2008-asdb-xxxx-xxx_md](../../includes/tsql-appliesto-ss2008-asdb-xxxx-xxx-md.md)]

  Returns information about encrypted values of column encryption keys (CEKs) created with either the [CREATE COLUMN ENCRYPTION KEY](../../t-sql/statements/create-column-encryption-key-transact-sql.md) or the [ALTER COLUMN ENCRYPTION KEY (Transact-SQL)](../../t-sql/statements/alter-column-encryption-key-transact-sql.md) statement. Each row represents a value of a CEK, encrypted with a column master key (CMK).  
  
|Column name|Data type|Description|  
|-----------------|---------------|-----------------|  
|**column_encryption_key_id**|**int**|ID of the CEK in the database.|  
|**column_master_key_id**|**int**|ID of the column master key that was used to encrypt the CEK value.|  
|**encrypted_value**|**varbinary(8000)**|CEK value encrypted with the CMK specified in column_master_key_id.|  
|**encryption_algorithm_name**|**sysname**|Name of an algorithm used to encrypt the CEK value.<br /><br /> Name of the encryption algorithm used to encrypt the value. The algorithm for the system providers must be  **RSA_OAEP**.|  
  
## Permissions  
 Requires the **VIEW ANY COLUMN ENCRYPTION KEY** permission.  
  
 [!INCLUDE[ssCatViewPerm](../../includes/sscatviewperm-md.md)] For more information, see [Metadata Visibility Configuration](../../relational-databases/security/metadata-visibility-configuration.md).
