I believe that eavesdropping in a man in middle attack and the message is passing from the client to server the man sitting at ISP or network hackers can look at what message I am sending. Heard that this can be easily done with wireless networks.
Well, how can I prevent from eavesdropping without SSL?
Does encryption help me in any way?
Will sending a bar code with my message help me?
Is there any other way to prevent eavesdropping?
Also what are the uses of SSL?
Is it only used to prevent attackers from eavesdropping or does it have any other significance?
