I've set up and instance to allow ssl connections as per this article:
http://technet.microsoft.com/en-us/library/ms189067.aspx
I've left the 'ForceEncryption' option set as 'no' due to logistical issues. (We need encryption from one source, but not necessarily other sources)
I plan to set up a mock up SSIS job to test with the client's certificate with the option to 'force encryption protocol' then again without it. If the data will transmit under both conditions, I think I'm good from a client perspective.
Is there any way to verify that the encryption is working though? Any way to verify that the data is encrypted?
