What is AES encryption in MySQL?

The MySQL AES_ENCRYPT function is used for encrypting a string using Advanced Encryption Standard (AES) algorithm. The MySQL AES_ENCRYPT function encodes the data with 128 bits key length but it can be extended up to 256 bits key length. It encrypts a string and returns a binary string.

What kind of random key do you need for AES 256?

For AES-128 you want a 128 bit random key, or 32 hex characters: For AES-256 you want a 256 bit random key, which is 64 hex characters: The MySQL documentation fails to note that the IV (initialization vector) must not be reused for multiple encryptions, and of course the IV must be stored to allow for decryption.
