SQL Server encryption and SQL Server encryption
Encryption in SQL Server is hierarchical, and each upper layer provides lower protection.
Instance:/**SMK (Service Master Key) is generated when SQL Server is installed. It is protected by Windows DPAPI (Data Protection API ).**/
/** Create a Database-level DMK (Database Master Key), protected by SMK **/Create mast
We have introduced the core implementation principles of mainstream double-layer encryption shells,And compatibility, while simplifying the encryption Shell Core with security considerations.The compatibility and security of the encryption Shell Core are discussed, and the Implementation Mode of the encryption Shell Co
Oracle's transparent data encryption is part of Oracle's Advanced Security Options and requires additional software fees. This option can be encrypted in combination with multiple means, including using Wallet (PKCS #12 standard) and supporting PKCS #11 RAS hardware devices.
In 10 Gb, transparent encryption supports column-level encryption, while in Oracle 11gR2,
What is distorted encryption transformation? This is a software I developed. The official term may be "mixed encryption". I name my software "distorted encryption transformation technology. I spent more than a year developing this software on and off, but I didn't do any promotion. This software has not been made public until now.
In the real environment, we will encounter the loss or theft of database backup disks. At this time, malicious destructive parties only need to restore or attach the database to view data. Next, I will introduce the Transparent Data Encryption method to protect your database. If data A is encrypted using TDE, the database uses A certificate-protected encrypted data key because it cannot be restored or attached to A backup disk.
1. What is TDE?

Symmetric encryption has many a
In the previous article, I introduced some important classes of the enterprise database cryptographer module, and introduced the extended interfaces provided by the enterprise database cryptographer module. Today I will perform extended development based on these interfaces, implements two encryption and decryption methods (discrete encryption and symmetric encryption

In actual applications, symmetric encryption is not enough. In more cases, symmetric encryption and asymmetric encryption are used in combination. asymmetric encryption (public key encryption) features slow speed, different keys for
The classical symmetric encryption algorithm is DES algorithm, and then derives the enhanced des algorithm of 3DES, TripleDES and so on. Moreover,. NET also provides symmetric encryption algorithms such as RC2, Rijndael, and so on. The details are detailed below.
DES encryption algorithm
The most classical algorithm in symmetric
Cloud encryption: Data Encryption technology used on the cloud (1)
Although many enterprise organizations want to make full use of cloud computing, data security remains the primary concern. However, with the help of many cloud solutions, it is expected to achieve and enjoy effective data protection and strong encryption on the cloud.
As business regulation and
[AES]
A symmetric encryption algorithm, used by DES.
For more information about encryption, see Java encryption and decryption symmetric encryption algorithm asymmetric encryption algorithm MD5 BASE64 AES RSA

There are many codes. Some of them are not the content cod
Before introducing the encryption function, let's first introduce the principle of data encryption: it is to process the original plaintext file or data according to a certain algorithm to make it a piece of unreadable code, it is usually called "ciphertext". In this way, we can protect data from illegal data theft and reading!

Speaking of bidirectional encryption, if previously in. NET development in the addition/decryption of friends are not unfamiliar, commonly used algorithms have DES, AES and so on. In the RT application, also provides the encryption related API, the algorithm naturally is the same, only the API encapsulation way is different, because RT is not completely managed code, but also resembles the form of the COM p
For a long time, the frequent occurrence of data breaches has caused a certain crisis. The website encounters ******, the external file is stolen by the third party, the competitor steals the trade secret ... This kind of data leakage event caused by countless economic losses, for the current enterprises and institutions, internal data security is particularly important, not only related to the enterprise's economy, but also related to the development behind the enterprise.So, how should enterpr
Useful PHP with public key cryptography class sharing (every time encryption results are different OH), PHP encryption
Web Interactive security has always been a major site of the first solution, this article introduces the PHP encryption class is very practical oh, with the public key, this is the biggest bright spot, no public key is not decrypted, plus densit
How to implement RSA encryption and ASP. netrsa encryption in asp. Net
In our practical use, encryption is an important means to ensure data security. In the past, MD5 and SHA1 algorithms were used for data encryption when ASP was used. Although these two algorithms are fast and effective, they cannot be used to revers
Practical PHP shared with public key encryption class (different encryption results every time), php encrypted
WEB interaction security has always been the primary solution for every major website. The PHP Encryption Class introduced in this article is very practical. It has a public key. This is the biggest highlight and cannot be decrypted without a public key,
