Encryption and decryption of MySQL database
This article mainly introduces "MySQL database encryption and decryption mode". In the daily operation, I believe that many people have doubts about the encryption and decryption mode of MySQL database. The editor consulted all kinds of materials and sorted out simple and easy-to-use operation methods. I hope it will be helpful to answer the doubts of "MySQL database encryption and decryption mode". Next, please follow the editor to study!
Data encryption and decryption are very important in the field of security. For programmers, storing user passwords in ciphertext in the database is of great significance for intruders to steal user privacy.
There are a variety of front-end encryption algorithms for data encryption and decryption. Below, I recommend a simple database-level data encryption and decryption solution. Take the MySQL database as an example, it has built-in encryption function (AES_ENCRYPT ()) and decryption function (AES_DECRYPT ()).
Insert encrypted data into the table
Double-click the code to select all 1 2 3INSERT INTO userdata (username,pasword,encryptedpassword) VALUES ('smith','htims',AES_ENCRYPT (' htims','key'))
The above insert statement has three fields, user name, password, and encrypted password. The AES_ENCRYPT () function needs a "key" to help with encryption, as well as decryption (remember! ).
The following is a screenshot of the data in the table:
Query encrypted data from a table
Double-click the code to select all 1 2SELECT username,pasword,AES_DECRYPT (encryptedpassword,'key') FROM userdata
The above query statement uses the AES_DECRYPT () function.
When the "pasword" and "decryptedpassword" fields have the same value, that is, you decrypt the user's password.
At this point, the study of "MySQL database encryption and decryption" is over. I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it!
