Is there any way to be able to hide the passwords that my users register, so that when the database is checked, it shows ********* or encrypted, some function of SQLite?
On the other hand, if there is no function to do that, my system has a login and registration that works, but the passwords are in a simple string, if I work the encryption in the servlets I would like to know what classes I should use, I suppose that for At the time of registration, the password is encrypted and for login it is decrypted for authentication?
