Hi forum,

I am working on packet capturing, for this i used jpcap using this i am able to get the packet data and able to convert this stream in to string format.i am getting this data for all web sites which i can open in my browser.
but i have a problem with mail contents i.e. if i access the gmail of my account then there i perform actions like read ,delete ,send mails etc.
while in this process if i check my program i am not able to get any related data from the packets that i capture .
why i am not able to extract the data for these mails but i am able to extract the data for all sites as i said.
how can i get the packet data for mails . please assist me.

Thanking you in advance.

I think Gmail uses HTTPS; can jpcap handle that? You may wish to use a tool like WireShark that shows all traffic going in and out.

Once Gmail is open, the AJAX communication may still use HTTPS. Have you looked at the traffic using WireShark?

yes i looked the traffic using wireshark ,
while using wireshark for gmail i found two protocols (tcp & tlsv1) , while using the following stream options there is a text but not clear as like http related sites.

TLS means it's using HTTPS - so it's encrypted, and there's probably no way for jpcap to get at the cleartext.
