Encrypting a field in a database?

Question

PHP

So I encrypted the key using Laravel methods and saved it, then at the entrance I check on the "cast" whether it matches the one in the database. But, the next need arose.
The user has a key, I want to encrypt it in the database (for storage), in case someone hacks the database.
However, the user, the owner of the key, can view or change it.
An example, a product: its key is encrypted in the database, however, after the purchase, I send the key to the user, he can see it.
How to do this?

Answer 1

You confused what is encryption and what is encoding.
The string that is written in password in Laravel, the framework encrypts it in the bcript algorithm, it is almost impossible to decode such a hash.
Create a column where you will write encoded passwords according to the algorithm that you choose or come up with yourself.
But I’ll tell you the idea right away ... You can’t store passwords like that ...
