Comments: SQL Server has built-in encryption to protect various types of sensitive data. In many cases, this encryption technique is completely transparent to you. When data is stored, it is encrypted and used automatically. In other cases, you can choose whether the data is encrypted.

immediately! There is no encryption DEK certificate, the database will not open, attached to other servers can not be used, database files will not be hack. If a DBA wants to legitimately move a database from an instance of SQL Server to another instance of SQL Server, sh

Encryption on SQLServer built-in encryption on SQLServer is used to protect various types of sensitive data. In many cases, this encryption is completely transparent to you. When data is stored, it is encrypted and used automatically. In other cases, you can choose whether the data is encrypted. SQLServer can encrypt the following components:

Start： -------------------------------------------------------------------------------- On the network, you see the methods of encrypting and decrypting SQL Server 2000 and SQL Server 2005 stored procedures, and then you analyze the code and find that they all have the same principle. I later wrote two stored procedure

Preface : Before SQL Server 2005 and SQL Server 2008. If you want to encrypt sensitive data, such as financial information, payroll, or identity card numbers, you must use an external application or algorithm. SQL

Server side and client's key system is not the same, called Asymmetric Key system RSA algorithm is based on modulo operation x mod n, in fact: [(a mod n) + (b mod n)] mod n = (a+b) mod n[(a mod n)-(b mod n)] MoD n = (a) mod n[(a mod n) * (b mod n)] mod n = (a*b) mod n so there (a mod n) ^d mod n = a^d mod n message/message (message) is actually just a bit mode (bit PA Ttern), each bit pattern can be represe

In SQL Server, encryption is hierarchical, and each upper layer provides protection.650) this.width=650; "src="/e/u261/themes/default/images/spacer.gif "style=" Background:url ("/e/u261/lang/zh-cn/ Images/localimage.png ") no-repeat center;border:1px solid #ddd;" alt= "Spacer.gif"/>650 "this.width=650;" src= "http ://s3.51cto.com/wyfs02/m00/70/99/wkiol1w583ojd3bx
