Database Encryption with DB Certificates


SQL Servers Database Encryption on Swim lanes
This document is create on May 2nd, 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'

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.

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.
