Are connections to databases encrypted?
When transferring data between a SQL Server instance and a client application, it is best practice for all connections to be encrypted (through TLS or SSL), as this ensures that the data is kept private. On the other hand, this doesn’t always work out since it either isn’t practicable or hasn’t been organized (a default installation of SQL Server will not normally include connection encryption).
How is encrypted data stored in MySQL?
If you do: update mytable set myfield = AES_ENCRYPT(‘some value’, ‘your secure secret key’);
Encrypt data:
- Public keys can be kept in a user’s database and are accessible to the public.
- The user’s password can be used to encrypt the private key.
- To encrypt, use the public key; to decrypt, use the private key.
- The data will only be accessible by the user.
How does MySQL use MD5?
A string’s MD5 128-bit checksum may be obtained by the usage of the MySQL MD5 function, which returns the result. A hash function that produces a 128-bit hash value is known as the MD5 message-digest algorithm. This method is used extensively. If the parameter was NULL, the MD5 function will return the value NULL, else it will return a binary string consisting of 32 hexadecimal digits.

What does MySQL’s super privilege mean?
It is possible to end other sessions or alter the way the server functions by using the SUPER command. Changes to passwords and other access privilege information can be made with the use of privileges that have been given for the MySQL system database itself. Because passwords are kept in an encrypted format, it is impossible for an unauthorized user to decipher them and learn what the plain text password is.
How is MySQL able to keep the user connections open?
MySQL does not have its own thread implementation; rather, it depends on the thread implementation of the operating system that it is running on. Once a user establishes a connection to the database, mysqld initiates the creation of a user thread. This user thread is responsible for executing user queries and returning the results to the user until the user disconnects from the database.
