Arduino Ethernet

Good morning everyone, lately I've been working with the Ethernet module to create a local web page in my home network. I saw that there is the possibility to make the page with the login (username and password). I don't know if the password is encrypted, does anyone have a program already done with the login and password encrypted?

Good day to everyone and thank you who will help me :slight_smile:

Thank you very much for the quick response :slight_smile:
What do you do if instead of having wi-fi you use the ethernet shild? What should I change in the code?
