I have made a function similar to Baidu"s network disk, and now there is a problem.
none of my 4-bit extraction codes are encrypted to the database.
if you are encrypting to a database, you need an algorithm that can be both encrypted and decrypted.
because when the user wants to know the password, I need to take the password out of the database, decrypt it, and send it to the front end.
which algorithm is better?
