Making a password protected program

[jwkNwA7f]

I am making a password protected program. How can I make each character typed an '*'. I also would like to make it where only my program can access the file where the password is stored.

Thank you!

Would encrypting the file make it where only my program can read it?

If it is, how can I do it?
