Recently, our company branch are spread over the whole country. From one branch to another we use public internet to our HQ Server. Our client using Spark version 2.8.3. We use openfire 4.0.1 with ssl protocol enabled.
However, if we enable encryption message mode with lock icon on the top left then is it all the message are really fully encrypted? is it really save?
How about the sniffing method?
Thanks in advance.
