With the use of SHA1, it helps to keep the password more protected than storing them as plain text. The password (string) calculates and returns a password string from the plain text password string, and it returns a binary string. It returns the value of the old password and the implementation of the password() as a binary string. mysql-> select old_password(last_name) from myworld Using old password to ENCRYPT the first nameīy the use of this select statement, show the old password on a particular column on a table. mysql-> select user,host,password from er Here we have to show the user table and check that their passwords are empty by using the following statement. To display which accounts exist in the MySQL mysql-> select password(first_name) from myworld. Here we have to encrypt the password function on the particular column on a table with the select statement such as. Using the password function to ENCRYPT first name In the following figures, we have a database table "employees" and use it with some query with showing results such as follows. The password also stores as a record on the server. The password function returns it in string form and restores a password in plain text. Recover a password in text form and set the old password, and select it in the text form. The password function encrypts the string into a binary form. The password function ismainly used for authentication. CREATE USER tmpusertocreateapassword WITH PASSWORD 'yourpassword' Read the password with SCRAM encryption. Create a user with the password you need to encode. TO Jameslocalhost Query OK, 0 rows affected (0.18 sec) Let us check the user has been created or not. Now flush the privileges using a flush command.In the MySQL server, we have to explain the password function() and how it will recover a password in its string form. If for instance, you're using migration files, you probably have to create two different files just ofr those two commands. The following is the query to grant all privileges to the newly created user. Look at the sample output, the user James has been created successfully. The following is the output displaying the new user we created above +-+ Let us check the user has been created or not mysql> select user from er Some users have old encryption and some users have new SHA-512 encryption. Courier is working with that and user can login using old encryption method and SHA-512 encrypted passwords. The following is the query to grant all privileges to the newly created user mysql> GRANT ALL ON *.* TO OK, 0 rows affected (0.18 sec) I have database with a password field that is encrypted in MySQL format encrypt (MD5) so its limited to 8 chars and SHA-512. Mysql> CREATE USER IDENTIFIED BY 'James123456' The query is as follows mysql> use MySQL MySQL server uses the PASSWORD function to encrypt MySQL passwords for storage in the Password column of the user grant table. Let us create a new user with the help of the above syntax. The following is the syntax to grant all privileges to the created user GRANT ALL ON *.* TO flush the privileges using flush command flush privileges The syntax is as follows to create a new user with password CREATE USER IDENTIFIED BY 'yourPassword' Let us check the version mysql> select version() In Ubuntu systems running MySQL 5. You need to use CREATE command to create a new user with password in MySQL 8. This step outlines how to use the root MySQL user to create a new user account and grant it privileges.
