How do I anti-this?

Question

I have a hub I'm making in VB.net, I don't want people to find out my auth as it sends request for login through php and sql. I did obfuscate my file, but how can I make people not be able to trace where the program requests url requests? (For example fiddler)

Answer 1

You can secure login data using SSL.

Answer 2

How would I do this without paying some SSL stuff to encrypt my domain?
