This MySQL tutorial explains how to use the MySQL ENCRYPT function with syntax and examples. The MySQL ENCRYPT function is used to encrypt a string using UNIX crypt().
How does ENCRYPT work? The ENCRYPT function in MySQL uses the Unix crypt() system call to perform the encryption. It takes two arguments: the string to be encrypted and an optional salt value. The salt value is a two-character string that is used to add randomness to the encryption proces...
key is used to encrypt and decrypt the data, and it remains in the MySQL Server instance and is not accessible to users. Using a KDF is highly recommended, as it provides better security than specifying your own premade key or deriving it by a simpler method as you use the function. ...
