SSL is an https connection for a web page, using port 443 by default. in theory, i can go to your web page via https, but your web server goes to a different server for SQL data via the default of port 1443. so the data between your Web server and your SQL server is not encrypted. , but when the data is passed back to me via https SSL on the web connection, it is encrypted.
The same thing for when you connect directly to the SQL Server via SSMS or your application or whatever...the traffic passed back and forth is not encrypted.
That is the SQL specific info we were giving you, so you can easily force the traffic to and from the SQL server to be encrypted.
