Row-level encryption, in which each row has a unique password for all of its cells. Cell-level encryption, in which each individual cell has its own unique password. Tablespace-level encryption, in which each tablespace has a unique password for all of its contents.
Can database be encrypted?
Databases can be encrypted at the database level, application level, table level or even at the column level. All encryption methods use keys for decryption. There are different methods of database encryption possible: Transparent encryption: Encrypts stored data at the database level.
How are rows in a database encrypted?
Say I had a database, where all of the rows of a database column is encrypted at the application level using a single passphrase, “SECRET”, using password based key derivation: Both the random salt and IV ensure that encrypting the same data for two different rows will produce different encrypted values.
How to implement row level security in SQL Server?

Any rows that are filtered or blocked aren’t affected. If a dbo user, a member of the db_owner role, or the table owner queries a table that has a security policy defined and enabled, the rows are filtered or blocked as defined by the security policy.
How do you assign security labels to rows?
You can accomplish this by assigning one or more security labels that define the level of security you want for the data rows of the table. This feature secures your database tables at the row level, and assigns these rows different levels of security based on security labels.
