Article Title: Use encryption commands to ensure the security of the Solaris server (figure ). Linux is a technology channel of the IT lab in China. Includes desktop applications, Linux system management, kernel research, embedded systems, open-source, and other basic categories. The security of Solaris server systems is closely related to their

Data encryption is the new data security feature of SQL Server 2005, which is an important improvement for application developers. This paper discusses SQL Server 2005 data encryption characteristics and how to use this feature to guarantee the data security of the system from the point of view of program developers. S

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 procedures, a cryptographic stored procedure (Sp_encryptobject), and a decryption stored procedure

When a user database is available and TDE is enabled, encryption is implemented at the page level when it is written to disk. Decrypts when the data page is read into memory. If a database file or database backup is stolen, the original certificate that is not used for encryption will not be accessible. This is almost the most exciting feature of the SQL Server2008 security option, and with it we can at lea

SQL Server 2014 CTP2 publishes a feature for backup, which is native backup encryption. In view of the previously bad impact on the network database leakage events, is essentially a database backup leaked to the third party, SQL Server's original data backup can make even if the backup itself is stolen, without the encryption certificate can not be used, this eff

Start: -------------------------------------------------------------------------------- On the network, we can see how SQL Server 2000 and SQL Server 2005 encrypt and decrypt stored procedures. Later, we analyzed the code and found that they work in the same way. Later, I wrote two stored procedures, sp_EncryptObject and sp_EncryptObject, based on the actual application environment. They can be applied to t

problem with the earlier version of Sha, currently using SHA-1, which can produce a 160-bit digest, This makes it more effective against brute-force attacks than 128-bit hashes.Since the one-way hashing algorithm is public, others can change the original text before generating another digest. The solution to this problem can be achieved by HMAC (RFC 2104), which contains a key that can be identified only by people with the same key.Four key negotiation processBecause of the slow speed of symmet

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:

In versions 6.0 and 6.5 of Microsoft SQL Server, 16-bit and 32-bit client software set encryption options when using multi-protocol network libraries to encrypt data online. SQL Server relies on the Microsoft Windows NT RPC Application interface to complete network data encryption
