Shawn Wang is a developer of PostgreSQL Database Core. He has been working in HighGo Software for about eight years. He did some work for Full Database encryption,  Oracle Compatible function, Monitor tool for PostgreSQL, Just in time for PostgreSQL and so on. Now he has joined the HighGo community team and hopes to make more contributions to the community in the future.

I have been working with the PostgreSQL community recently to develop TDE (Transparent Data Encryption). During this time, I studied some cryptography-related knowledge and used it to combine with the database. I will introduce the TDE in PostgreSQL by the

After introducing the difference between the AES modes, in this document, I will put the results about the AES modes performance. The following tests just use one core CPU. AES-NI:The Advanced Encryption Standard Instruction Set (or Intel Advanced Encryption Standard

Just-in-time compilation of SQL statements is one of the new features in PostgreSQL 11. Just-in-Time compilation (JIT) is the process of turning some form of interpreted program evaluation into a native program and doing so at runtime. While doing some

Recently, I did some work with Sawada-san on the TDE. So I studied on the encryption algorithm. So far, I study five modes in the AES. In this document, I will introduce the difference in the five kinds of mode.

Key management consists of four parts: key generation, key preservation, key exchange, and key rotation. Key Generation Only for the study of symmetric encryption, so I mainly introduce symmetric encryption. The symmetric password generation method is: A random number is
