Encryption?

How do people get these encryptions packets. senario that i see when i read an article on Encryption is, Let's say a website has a text page not a SSL, they type name and hit enter that information is then sent with the tcpip protocol to the destination server. How do people filter out the information from client to server. to see what the person wrote.

hi,

I didnt quite get ur question.

We can use a network sniffing program to see what is transmitted across the network.At the clients end the packet is reconstructed according to a unique identification scheme and u get to see its contents.

Are u asking how secure http works?
