APPLIES TO: yesSQL Server yesAzure SQL Database noAzure Synapse Analytics (SQL DW) noParallel Data Warehouse

Returns information about encrypted values of column encryption keys (CEKs) created with either the CREATE COLUMN ENCRYPTION KEY or the ALTER COLUMN ENCRYPTION KEY (Transact-SQL) 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.

Name of the encryption algorithm used to encrypt the value. The algorithm for the system providers must be RSA_OAEP.
