Database Encryption with DB Certificates

SQL Servers Database Encryption on Swim lanes

This document is create on May 2^nd, 2012 and is valid for Swim Lanes. Certificates are installed on LD4PRDCLT101 and this version of the certificate and key should be used across all swim lanes if needed.

Create a new Master Key

USE master;

GO

CREATE MASTER KEY ENCRYPTION BY PASSWORD = 'Password';

Go

--To Drop the masterkey

--DROP MASTER KEY

Create a new Certificate per Database that need to be encrypted

--database encryption key

CREATE CERTIFICATE DatabaseName1_Cert WITH SUBJECT = 'DatabaseName1 Certificate'

Go

CREATE CERTIFICATE DatabaseName2_Cert WITH SUBJECT = 'DatabaseName2 Certificate'

Go

CREATE CERTIFICATE DatabaseName3_Cert WITH SUBJECT = 'DatabaseName3 Certificate'

Go

--To Drop the certificate

-- DROP CERTIFICATE DatabaseName1_Cert

Backup Master Key and certificates and use for restoring databases on a different server

      Use master

GO

Backup master key to file = 'C:\MasterKey.key' encryption by password = 'Password' ;

BACKUP CERTIFICATE DatabaseName1_Cert TO FILE = 'c:\DatabaseName1_Cert_file.cert'

WITH PRIVATE KEY ( FILE = 'c:\DatabaseName1_Cert_key.cert' ,

ENCRYPTION BY PASSWORD = 'Password'

);

BACKUP CERTIFICATE DatabaseName2_Cert TO FILE = 'c:\DatabaseName2_Cert_file.cert'

WITH PRIVATE KEY ( FILE = 'c:\DatabaseName2_Cert_key.cert' ,

);

BACKUP CERTIFICATE DatabaseName3_Cert TO FILE = 'c:\DatabaseName3_Cert_file.cert'

WITH PRIVATE KEY ( FILE = 'c:\DatabaseName3_Cert_key.cert' ,

ENCRYPTION BY PASSWORD = 'Password'

);

Create certificates from a backup certificate on another server, (note:  the master key should be created before this can be done)

CREATE CERTIFICATE DatabaseName1_Cert

FROM FILE = 'C:\DatabaseName1_Cert_file.cert'

WITH PRIVATE KEY (FILE = 'C:\DatabaseName1_Cert_key.cert' , DECRYPTION BY PASSWORD = 'Password')

CREATE CERTIFICATE DatabaseName2_Cert

Querying the SQL Server System Catalog FAQ

How do I find all the tables that do not have a clustered index in a specified database?

Before you run the following queries, replace  with a valid database name.

Transact-SQL

USE ;

How do I find the columns that depend on a specified CLR user-defined type or alias type?

Before you run the following query, replace  with a valid name and _type_name> with a valid, schema-qualified CLR user-defined type, or schema-qualified alias type name. The following query requires membership in the db_owner role or permissions to see all dependent column and computed column metadata in the database.

Transact-SQL

USE ;

    ,c.name AS column_name

The following query returns a restricted and narrow view of columns dependent on a CLR user-defined type or alias, but the result set is visible to the public role. You can use this query if you have granted REFERENCE permissions on your user-defined type to others and you do not have permission to view the metadata of the objects others have created that use the type.

How do I find the views, Transact-SQL functions, and Transact-SQL stored procedures that depend on a specified CLR user-defined type or alias type?

Before you run the following query, replace  with a valid name and  with a valid, schema-qualified CLR user-defined type, alias type name.

The parameters defined in a function or procedure are implicitly schema bound. Therefore, parameters that depend on a CLR user-defined type or alias type can be viewed by using the sys.sql_dependenciescatalog view. Procedures and triggers are not schema bound. This means that dependencies between any expression defined in the body of the procedure or trigger and a CLR user-defined type or alias type is not maintained. Schema bound views and schema bound user-defined functions that have expressions that depend on a CLR user-defined type or alias type are maintained in the sys.sql_dependencies catalog view. Dependencies between types and CLR functions and CLR procedures are not maintained.

The following query returns all schema-bound dependencies in views, Transact-SQL functions, and Transact-SQL stored procedures for a specified CLR user-defined type or alias type.

Transact-SQL

USE ;
GO
