I am maintaining a C# app that's been cracked by people creating spoof auth servers.
I want to encrypt all the communications between the client and server to prevent this happening to my next release.
I can see that PHP has a way to secure stuff. http://www.php.net/manual/en/function.openssl-private-decrypt.php
What I can't find is the C# that will allow me to use the same built in libraries.
Can anyone help?
Did you look into SslStream?
