I'm glad to have two functions that are useful to you. The first one is used to generate the serial number. The second one is used to encrypt some strings. modify it a little bit, you can find the effect of some hidden characters such as itb ********* @ gmail.com that we often see when retrieving the password. The code is as follows: /** * Serial
