postgresql data encryption

For a database administrator, security is one of the most important aspects to consider when protecting a database that you support. We use a variety of mechanisms and techniques to protect our data and databases, such as firewalls, authentication, and data encryption. But although we set security for our environment, there are always problems with database secur

If you are running a Web application that uses MySQL, it can store passwords or other sensitive information in the application. Protecting this data from access by hackers or prophers is an important concern, because you cannot allow unauthorized users to use or destroy applications, but also ensure your competitive advantage. Fortunately, MySQL If you are running a Web application that uses MySQL, it can store passwords or other sensitive information

Think of TDE (Transparent Data Encryption ). Tde msdn description: TDE performs real-time I/O encryption and decryption on data and log files. This encryption uses the database encryption key (DEK), which is stored in the databas

This article assumes that you are familiar with C # and bit operations. Summary AES (the Advanced encryption Standard) is the specification used by the National Institute of Standards and Technology for the encryption of electronic data. It is expected to become a recognized means of encrypting financial, telecommunications and government digital information. T

Three methods for data encryption in Linux Data encryption is a very reliable security measure/precaution. People with personal data or important data should encrypt the data. The role

There are many ways to do this, and the method used here is more secure. Then there will be time to add another method.The method is divided into three steps: Backing up data, creating a new table structure, importing dataBackup data: >>\copy table_name to '/home/bak/table_name.sql ';Create a new table structure: Copy the SQL statements from the original table structure, delete unnecessary and inappropriate

In the world of computer software development, there are many programming languages, and data may have different forms of representation in different languages, but data processing may, or is essentially the same; for example, the calculation process of data in an algorithm is the same. Here, I use encryption and decry
