Simply list the basic commands and share only my thoughts!First, the data addition / decryption principle explanationboth clients communicate on the Internet, in order to ensure the security of information, there is The SSL protocol is called a Secure Socket layer under the application layer above the TCP/IP model Transport layer. The goal is to encrypt the application layer's data to the client, and the so

Objective:For the SHA Secure Hash algorithm, not used before, just stay in the heard of the stage, today in the picture cache frame Glide source found that its cache key is not MD5 encryption algorithm, but SHA-256 encryption algorithm, this just hook up my curiosity, so while the night nothing, To learn a bit.Several other encryption methods: RSA

Label:Export Import of PostgreSQL dataTo export data from a PostgreSQL database: $ pg_dump-u postgres-f mydatabase.sql mydatabase When importing data, first create the database and then import it with Psql: $ createdb Newdatabase$ psql-d newdatabase-u postgres-f Mydatabase.sql Create a database CREATE DATABASE Test

First to describe the situation, first there is a batch of users before the default password for 6 8 and then after the MD5 encryption for storage, it is now necessary to change according to the user ID number 6 digits as the password.1. First found that we sqlserver05 the above version is the MD5 encryption method, and then we verify that its encrypted data with

The role of data encryption in our lives has become increasingly important, especially given the large number of transactions and data transmissions that occur on the web. If you are interested in adopting security measures, you will also be interested in understanding the range of security features provided by PHP. In this article, we will describe these feature

adopt it.3. Turn off auto-commit, use INSERT or multi-insert format SQL, insert large amounts of dataCurrently not tested, but this program effect with the online introduction should also be good.4. Using temporary tablesThis option, temporary table in order to speed up, should not add any index and log, data stability after the index and limit, compression data, vacuum and other

I,Public KeyEncryptionAssume that I have two numbers: 1 and 2. I like the number 2 and keep it. I won't tell you (Private Key), and I will tell you that 1 is my public key. I have a file that cannot be viewed by others. I use 1 for encryption. Someone else finds this file, but he does not know that 2 is the decryption private key, so he cannot undo it. Only I can use number 2, that is, my private key, to decrypt it. In this way, I can protect the

This article explains how to use transparent Data encryption (TDE) to protect a database, including the files that are backed up. To understand that this feature can be used to improve the security of your database application, please check this article. STEP1: Use master; GO IF EXISTS (SELECT * From sys.databases WHERE name = ' Tdedemo ') DROP DATABASE Tdedemo; GO CREATE DATABASE Tdedemo; GO Next, create t

Encryption | The position of data encryption in our lives has become more and more important, especially considering the large amount of transactions and data transmissions that occur on the web.
