Your question: How does MySQL encrypt data?

How does MySQL encryption work?

MySQL Enterprise TDE enables data-at-rest encryption by encrypting the physical files of the database. Data is encrypted automatically, in real time, prior to writing to storage and decrypted when read from storage. As a result, hackers and malicious users are unable to read sensitive data directly from database files.

How does MySQL store encrypted data?

For storage of encrypted data, you could use a BLOB field, and use MySQL’s built in encryption functions. Example: update mytable set myfield = AES_ENCRYPT(‘some value’, SHA2(‘your secure secret key’, 512)); If you prefer to do the encryption/decryption in the application code, take a look at PHP’s Mcrypt functions.

What encryption does MySQL use?

MySQL supports encrypted connections between clients and the server using the TLS (Transport Layer Security) protocol. TLS is sometimes referred to as SSL (Secure Sockets Layer) but MySQL does not actually use the SSL protocol for encrypted connections because its encryption is weak (see Section 6.3.
